After the uv inkjet printer nozzle is blocked, how to clear it?

During the use of uv inkjet printers, improper operation sometimes causes nozzle clogging, which affects printing efficiency and causes unnecessary loss. Because the nozzles are not cleaned in time, the uv printer nozzle clogging damage will be further increased. Several nozzle cleaning methods, I hope to help everyone.

The first type: the scope of application of the immersion method: the resistance is lighter

Step 1: 

Prepare a small flat plate, place the nozzle flat in the tray, and then inject the special cleaning solution for the uv flatbed printer into the tray. The depth is just to immerse the nozzle part. Be careful not to splash water on the cable plug and drive. On the board, the first soaking time is about one hour.

Step 2: Cleaning

 UV Inkjet Printer

1. Gently suck the water stain on the nozzle with a damp cloth. Do not wipe the nozzle at the bottom of the nozzle.
2. Repeat the process for all nozzles to be cleaned. Use a clean area for the cloth for each nozzle.
3. If the nozzle is clogged, the distilled water can be slightly heated and placed in a small amount on the plate. When the nozzle is placed on the plate, the water surface should not leak higher than the bottom 2CM because the water may leak to the back of the chip.
4. Stand the nozzle upright in warm water. Wait for 30 seconds, then test the nozzle after sucking dry.
5. Each nozzle should be cleaned with clean water.

The second type: nozzle injection flushing method Scope of application: severely blocked.

Tools: 95% alcohol, a clean cup, a syringe, and an infusion set.
Working principle: Using the pressure generated by the siphon action of the syringe, an organic solvent such as alcohol is injected into the print head to clean the dry ink head.
Use a plastic tube of the infusion set, one end is inserted in the 5ml syringe, the other end is inserted into the nozzle ink inlet of the nozzle to be flushed, and the distilled water in the syringe is pressed into the nozzle, so that the pressure is not too large, so as to prevent the water pressure from squeezing the nozzle Internal waterproofing adhesive. This process needs to be repeated several times until it is seen that each of the ink outlets ejects a fine water column. In this way, the blocked nozzle is completely cleaned.

The third type: ultrasonic instrument cleaning method Scope of application: the situation is very serious

UV Printing Machine

Working principle; the ultrasonic cleaning machine is used to generate strong ultrasonic waves, so that the water molecules vibrate violently, and the fine dry ink particles are shattered and dissolved in water to achieve the purpose of cleaning.
The reminder here is that if the uv printing machine nozzle is blocked, stop printing immediately, and check the degree of blockage. If you can't clean it yourself, please contact the uv printer manufacturer to help solve it. Do not blindly disassemble the nozzle.

Why is the sublimation printer ink always faded,how to avoid it?

We know the picture printed by color inkjet printing, the rich color comes from the dye in the sublimation printer ink. If the fading phenomenon is definitely caused by the change of the dye, what kind of factors can lead to the dye in the ink? What happened?
One is the irradiation of ultraviolet rays, and the other is that the dye in the

Sublimation Printer Ink

dye sublimation ink encounters some redox-containing substances, which causes the chemical structure of the dye to change, thereby causing fading. The fading of ultraviolet light is of course related to the intensity of ultraviolet light. We know that the picture made by indoor ink is placed in a place where there is no direct sunlight in the house, and it only bears the illumination of some indoor lights. In this case, if the dye in the ink The light fastness grade is 5~6, so its indoor storage time is two or three years, so when encountering fading, first of all, it depends on whether the picture is overexposed by ultraviolet rays, such as whether the ultraviolet light of the lamp in the light box exceeds the standard. The use of inferior lamps to cause fading of the lamp picture is one of the common causes of fading of the lamp. Another reason for fading is that the dye encounters some redox species. When the uv flatbed printer ink is applied to the coated medium, it is coated with a gelatinous film, if coated or filmed. There will be fading in the presence of oxidizing substances. For example, when our hands are inadvertently stained with ink, it is very difficult to wash off. It will be washed off immediately after disinfection with 84. This is the reason why this fading occurs generally. Said to have the following characteristics:
1. The light or neutral color of the picture feels very fast and sometimes only a few hours.
2. This kind of picture will fade quickly even if it is placed in a dark place.

 Mimaki Printer

3. The color of the screen fades to a certain extent will not fade (the description reflects a part), the specific situation will be slightly different. At present, in the domestic market, the material coating is generally passed through, and the lamp is inferior. The fading of the film is also happening from time to time. We can understand this through some practical tests.
High-precision sublimation printing ink with bright colors and strong UV resistance; the ink production process passes through 3 mandatory filter systems, the ink particles are finer, the printing is smoother, and the ink head will never be blocked, which can effectively extend the ink head of the printer. Service life!

When sublimation printing ink touch your skin and clothes,how to clen it?

Anyone in the printing industry knows that it is very easy to get the hands and clothes when adding sublimation printing ink to the ink cartridges, and it is very difficult to wash. It is very painful! Today I will share some experiences in cleaning the printer ink.
The sublimation printer ink is usually composed of a solvent, a colorant, a surfactant, a pH adjuster, a drier, and other necessary additives. It is a chemical mixture of polymers. It is very difficult to wash your hands and clothes.

How to clean the ink on your hand:

1. Gasoline + detergent
Pour the gasoline into the palm of your hand, then squeeze the detergent, rub it for 2 minutes, then wash it. After testing, the ink is reduced by 80%, but there is still ink
shadow, which can be repeated 2 times again, and the ink stain is eliminated.
2. Alcohol + soap

 Sublimation Sublimation Ink

Pour some alcohol on your hands, wash with soap for 3 minutes, then rinse with water. After testing, the ink is reduced by half, then it can be gradually eliminated several times.
3 .Cleansing oil + detergent
Apply the cleansing oil to your hands slowly, rub for 2 minutes, then mix with the
detergent for 2 minutes, rinse with water, and the ink is slightly reduced after the test, and it will gradually fade over and over again.
4. Banana water + washing powder
Use banana leeches, add washing powder and then rinse with water. After the test ink is very light, then wash it again, the ink stains will gradually fade.
5. Apply ink stains with glutinous rice soup, then wash with hand sanitizer, then rinse
with water, repeat 2 - 3 times, and test the ink stains to disappear.
6. Wind oil + wipes
Apply the oil to the ink stains for 2 minutes, then use a wet wipe to remove it. The ink stains are lightened by half. Repeated scrubbing 3--5 ink stains disappear completely. Washing successfully does not hurt your hand.

How to clean the ink on clothes:

The difference in the nature of the inkjet sublimation ink, the method of cleaning the ink on the clothes will be different, so first of all to distinguish the nature of the ink, that is, water-based ink or oily ink stains.

1.The cleaning method of water-based ink:

(1).It can be directly used with the washing liquid. First, rinse with clean water and then apply the original liquid of the washing liquid to the ink stain, let it stand for 5
minutes, and then carry out regular washing;
(2).Soak the contaminated clothes in carbon tetrachloride and rinse them with water. When it is not cleaned with water, it can be wiped with 10% ammonia solution or 10% baking soda solution, and then washed with water.

 Sublimation Ink

2.The cleaning method of oily ink stains:

(1). Soak the clothes stained with the ink with an aliquot of ether and turpentine mixture, and wash off with gasoline after softening;
(2). When the clothes are dry, pour the alcohol (concentration above 80%) into the stain for 5 minutes;
(3). Apply the liquid of the laundry liquid to the stain, completely cover the stain, leave it for 5 minutes (can be gently rinsed), and add the washing liquid to wash it regularly.Suggest:
The amount of water should be such that the clothes are just wet, the color of the colored clothing and the net amount of the collar are increased or decreased according to the amount of water. If the color stains are not removed after soaking overnight, continue to extend the soaking time.

The above has introduced some questions about how to wash off the sublimation ink, and introduced some things that are very common in daily life, so don't worry when you encounter this situation. The first is to identify the nature of the ink, and then pay attention to choose a reasonable treatment. In addition, you should pay attention to your work, try not to get the ink on your body, the staff should pay attention to preventive measures, such as wearing gloves, so as to avoid the trouble of being stained with ink.

When sublimation printing ,what should we do if CISS ink cartridges produce bubbles

When using sublimation printing technology to print pictures, the printing effect is not good in some places. How to take the bubbles in the cartridge? What are the phenomena caused by the bubbles in the cartridge?

1.Fault phenomenon

(1).The continuous ink supply system has been working for a few months and cannot be printed now.
(2).Many cleaning commands are executed every day before normal printing.
(3).Printed test leads always have unfixed breaks.
(4).The test line that was just printed is normal, but the line breaks after printing a few pages.
(5).Printing is always missing (usually black)
It has been a long time since the external ink cartridge was placed in the low position, and now the ink supply line does not enter the ink.

2.Solution

The above failure phenomenon is caused by the foaming of the ink in the ink cartridge. After six months of use, the continuous ink supply system gradually accumulates ink from a small amount of tiny air bubbles in the ink and a small amount of air bubbles entering the print cartridge from the print head. The maintenance method is not complicated, and the bubbles are taken out and replaced with normal ink.
Incorrectly lowering the external ink cartridge will also accelerate the formation of the ink chamber foam, even if the continuous ink supply system of the original EPSON ink cartridge is used.
To troubleshoot this type of failure, please follow these steps:

 Sublimation Printing

(1). Remove the continuous ink supply system from the inkjet sublimation printer. After removal, the print cartridge should not be inverted and placed on the same level as the external ink cartridge. If a sealing plug is used during initial installation, insert the sealing plug into each ink outlet on the bottom of the cartridge. For the model with the memory chip on the ink cartridge produced in the later stage of EPSON, since the ink outlet is equipped with a valve, a sealing plug is not required. Install a new or in-use original EPSON cartridge on the printer. This cartridge must be an original cartridge that has not been opened, unfilled, or damaged. The original EPSON cartridge can guarantee correct test results during testing. This step is essential.
(2). After the ink cart is returned to the position, the printer will perform a natural 
cleaning once. Please perform a nozzle check to print the test line. The cleaning and 
printing test lines can be repeated three more times until the test line is completely 
normal. Then print the test chart of four-color or six-color color block (depending on your model, the print setting is in 360DPI / plain paper mode), the color block test chart must be printed continuously for 3~5 sheets, and observe whether the printer works normally. If the print is abnormal, repeat the above steps. If the printer is still not working properly after 9 to 12 cleanings, let the printer rest for 12 hours before testing. In most cases, the printer will return to normal.
When the color patch test chart printed by the printer is stable, you can be sure that your printer nozzle is intact. Once you have concluded that your printer is normal, you can continue with the following steps to maintain your continuous ink supply system.
If you still cannot print normally after using the above method, please contact EPSON service center for warranty or contact printer repair shop for repair. Although the discontinuous ink supply system is faulty at this time, contact us can still get help. Before deciding to deliver to the EPSON repair center, please remove the parts and labels related to the continuous ink supply system, and do not mention EPSON the use of third-party ink or continuous ink supply system, only that you are using original EPSON ink cartridges. Explain the symptoms.
(3). When your sublimation printer is working properly, the following steps will return your continuous ink supply system to normal.

 Sublimation Printer

Insert the 50 ml disposable syringe tube (with the needle removed) into the ink outlet at the bottom of the print cartridge connected to the continuous ink supply system, tilt the syringe tube slightly, and slowly draw ink from the cartridge. The ink should be It is sucked from the external ink cartridge into the print cartridge through the ink line, and then continuously sucked into the syringe tube. When the syringe tube is full, observing the amount of ink and foam that is drawn will tell you what caused the continuous ink supply system to print poorly. The printer does not print the foamy ink normally, you must pull them out through the syringe.
Uncover the rubber plug of the external ink cartridge and inject the ink from the syringe into the external ink cartridge. This process does not waste ink, and the foamy ink turns into liquid ink after two hours.
This dye sublimation ink extraction process is repeated with a syringe until almost no foam is visible in the extracted ink. This requires approximately 100 ml of ink to be 
circulated. That is, it is necessary to repeat the ink extraction process twice.
Note: The ink extraction process should be slow, you can pause, and don't cut too fast.
Perform the above ink extraction process in the order of yellow → light magenta → magenta → light cyan → cyan → black. When changing color, be sure to clean the syringe with warm water. If your ink cartridge uses a sealing plug, the other ink outlets should be plugged with a sealing plug when operating in one color chamber.
(4). Put the ink cartridge together with the continuous ink supply system back to the 
printer, and check and debug until the normal operation according to the operation sequence in step 2 above.

Digital sublimation ink, what are the effective ways to reduce color loss?

At present, in the digital sublimation ink color management technology, the so-called color feature connection space is the color space of CIE1976Lab, and the color of any device can be converted into this space to form a "general" description mode, and then color Match conversion. Within the computer operating system, the task of implementing color matching conversion is done by the "color matching module", which is reliable for color conversion and has important significance for color matching.

So, how to achieve color transfer in the "universal" color space, to achieve loss of color or as little loss as possible?

Digital Sublimation Ink

This requires each device to generate a profile, the color profile of the device. We know that sublimation inks exhibit a variety of different materials, materials, and processes when presenting and delivering colors. In color management, high-fidelity rendering of the colors presented on one device on another device requires us to understand the color rendering characteristics of the colors on various devices. Since the device-independent color space, CIE1976Lab chromaticity space, has been selected, the color characteristics of the device are expressed as: the correspondence between the description value of the device and the chromaticity value of the "universal" color space. A color description file for the device.

Device color characterization file

Among the sublimation transfer ink color management technologies, there are three types of device color characterization files. The first type is the scanner profile, which provides standard documents of Kodak, Agfa, and Fujitsu and standard data of these originals. These originals are input by the scanner, and the difference between the scanned data and the standard original data reflects the scanner. The second type is the characteristic file of the display, which provides software to measure the color temperature of the display, and then generate a color block on the screen, which reflects the characteristics of the display; the third type is the printing device. The feature file, which also provides a set of software, which generates a graphic containing hundreds of color blocks in the computer, and then outputs the graphic on the output device. If it is a printer, the proof is directly printed, and the printing machine first outputs the film. , proofing and printing, measuring the output image reflects the characteristic file information of the printing device.

Sublimation Printing

The generated profile, that is, the color profile, is a sublimation transfer ink composed of three parts: a file header, a markup table, and a markup element data. A file header that contains basic information about the color signature file, such as file size, type of color management method, version of the file format, device type, color space of the device, chroma space of the feature file, operating system, device manufacturer , color reproduction target, original medium, light source chromaticity data, etc., the file header occupies a total of 128 bytes. A tag table, which contains information on the number of tags, storage location, and data size, without the specific content of the tag. The tag name name occupies 4 bytes, and each tag entry has 12 bytes. . The mark element data, which stores various information required for color management at a predetermined position according to the description of the mark table, and varies according to the complexity of the mark information and the amount of data of the mark.
For the color profile of the equipment in the printing enterprise, the operator of the graphic information inkjet sublimation ink processing is obtained in two ways.
The first way is to use the special profile creation software to generate the applicable color characterization files according to the actual situation of the existing equipment. The generated files are usually more accurate and more in line with the user's actual situation. As the state of equipment, materials, and process flows change or shift over time. Therefore, it is necessary to re-create the profile at intervals to adapt to the color response at the time.
The second way is when the device is purchased, the profile provided by the manufacturer along with the device, which can meet the general color management requirements of the device. When the device application software is installed, the profile is loaded into the system.

It stands out in many nozzles and has been used by many manufacturers. In terms of service life, Not only does it require the quality of the Epson five-generation nozzles, but also the maintenance in daily use.
In the daily maintenance of the Epson dx5 printhead, if the nozzle is clogged, the nozzle needs to be cleaned. The cleaning method is as follows:

The method to clean Epson five-generation nozzle:

1. Photo machine comes with nozzle cleaning: It can be automatically cleaned by the photo machine maintenance function.

 Epson DX5 Print Head

2. Ink cleaning: When the ink car is in the initial position, use a syringe with a hose to connect to the waste ink tube and draw about 5 ml of ink. (Note that during the ink extraction process, do not let the inner cylinder of the syringe rebound, which will cause each When the nozzle is mixed, if the nozzle is not tightly sealed during the ink extraction process, the ink can be lightly moved by hand to ensure a good seal between the nozzle and the nozzle protector. After the ink is pumped, the software is cleaned.
3. Flushing and cleaning: remove the ink cart, remove the ink bag, connect the syringe with the cleaning liquid to the ink column of the nozzle, push and withdraw with appropriate pressure, and spray the complete thin wire vertically to the nozzle.
4. Printing and cleaning: replace the ink with the phenomenon of clogging print head with “head cleaning agent”, use the vector graphics software to print the color block of the color, and the nozzle clogging phenomenon is cleared, and the original ink is replaced.
If the photo machine is left idle for a long time, professional maintenance of the nozzle is required. 

The following are the maintenance methods and steps:

Is the eco-solvent printer ink environmentally friendly? Is it harmful to people?

When we are using eco-solvent printer inks, we are worried about whether this ink is toxic and environmentally friendly. Below I will tell you some tips on using this inks.

1. What are the harmful effects of eco solvent ink on the human body? Is it poisonous?

Eco-solvent inks are still very safe and have low volatility and are slightly toxic. Only long-term contact staff need to use protective measures. As long as the human body does not eat, it is harmless to the human body.

2. What are the characteristics of eco solvent inks? What is the difference compared to solvents?

Eco-solvent Printer Ink

Compared with solvent-based inks, the biggest change in eco-solvent inks is environmentally friendly, mainly due to the reduction of volatile VOCs and the elimination of many toxic organic solvents (such as cyclohexanone, methyl ethyl ketone, etc.). Ventilation is no longer required in the production plant of the eco-solvent printer. However, we must see that the main component of weak solvent inks is still organic solvents. Objectively speaking, weak solvent inks are a classification of solvent-based inks and are an environmentally friendly version. The ECO of the weak solvent ink can be regarded as the abbreviation of Environmentally safe, uncoated media and Outdoor durable. The general promotion of the machine using ECO-solvent ink is environmental protection, high precision and outdoor weather resistance. In the ink production process, in addition to choosing an environmentally friendly solvent, the weak solvent ink also proposes two higher requirements compared with the solvent-based ink: one is to achieve a high-precision output and must have a dot gain on the ink. The control is better, and the other is that the filtration precision of the ink production process is higher.

Since inkjet eco-solvent inks take into account some of the advantages of aqueous inks and solvent-based inks, it can be said that it has rapidly developed between aqueous inks and solvent-based inks.

3. What are the characteristics of this inks on the market?

(1) Rich colors, realistic effects, wide color gamut, excellent color expression;
(2) Waterproof, resistant to abrasion and not easy to discolor.
(3) Imported raw materials, good dispersion stability, no plugging;
(4) Long-lasting outdoor performance, able to resist the effects of UV light and prevent color fading;
(5) It does not contain toxic solvents such as benzene, toluene, xylene or cyclohexanone, and has a very low taste;
(6) Good adhesion, fast drying;

4. How to better use this ink?

Eco-solvent Ink

(1) Due to some characteristics of the inkjet eco-solvent printing ink itself, it is necessary to be particularly careful when using the supply. Some friends use this ink, the outer ink cartridge is leaking, the elbow connecting the ink line is blocked, and finally the print head is broken. So with a corrosion-resistant continuous supply or ink cartridges, especially desktop printers must pay attention to this. Do not use the equipment for a long time, pay attention to the cleaning of the nozzle part, so as to avoid the clogging of the nozzle due to the evaporation and solidification of the residual ink.
(2) Eco solvent inks can be printed on some materials without coating, or by means of printer heating, etc., but for some smooth surfaces, ink alone is powerless, and ink will accumulate in Together, it is impossible to image clearly.

5. How to identify the real eco solvent ink?

(1) First of all, depending on the particle size of the eco solvent inkjet ink, the average particle size should be less than 1um, which allows the manufacturer to provide a test report on the ink by the laser particle size analyzer. If the manufacturer can't get the test laser particle size test report, 90% of it may be boasted.
(2) Secondly, it is necessary to smell the taste of this ink. If the taste is pungent, it is not a weak solvent, and the real weak solvent is almost tasteless. Some manufacturers use PMA as a eco solvent to deceive people.
(3) Finally, check on the machine to see if the color gamut is wide and whether the spray is smooth. The true weak solvent ink has a very wide color gamut and is resistant to light for more than 24 months.

Large format uv flatbed printing machine What is the uncoated of it?

What is the uncoated of large format UV flatbed printers? what is the benefit? These three are problems that plague new users. If you can't understand the difference well, it is easy to cause a lot of troubles for the use of late devices. Seriously, you may buy equipment that you can't use at all, and you will waste money.

 Large Format UV Flatbed Printing machine

The uncoated UV flatbed printer means that when printing part of the material, printing can be started without pre-pressing the surface of the material. It does not mean that all materials can be printed without coating. This coating-free printing is conditional.For example, the surface of the plastic material can be free of coating, and it is common to have a mobile phone case, a notebook case, and the like. Gypsum ceilings commonly found in building materials can also be printed without coating; however, some can not be printed without coating, such as glass, glazed tiles, metal, etc. Any surface density is high, smooth materials can not be directly printed.
So how is the coating free? The free coating is actually determined by the ink. The UV ink itself contains corrosiveness. In this process, the pigment component in the ink can adhere to the surface of the material to realize the entire printing process.Everyone who prints knows that printing something like glass, tile, or metal can't be printed directly. If you need to do some coating treatment on the material to print, then let's first talk about the benefits of using the coating:

1. The drying speed

The fast processing liquid is prepared by special chemical materials, and it is dried in about three minutes after spraying, especially in the smooth materials such as glass, porcelain and metal.

2.The printing quality is better

 UV Printer

If it is directly printed on some materials, it is mainly smooth and non-absorbent material, the effect is poor, and the effect is remarkable after using the treatment liquid. No matter whether the material is bent or folded for a long time, there will be no cracking or faulting on the surface of the material.

3.Wear resistance, waterproof

Since the composition of the treatment liquid has adhesive components, the adsorption force of the ink and the material after printing is very superior, far exceeding the wear resistance of the untreated state, and the waterproofness of the material after using the treatment liquid is far more than that. The coating state is many times.
Customers who have used uv flatbed printing machine know that 90% of the materials used to print glass, ceramics, metal, leather, etc. must be coated. Because the weak solvent ink directly prints the pattern, there is a great possibility that the ink is piled up and the printing and printing effect is poor. Must do pre-printing.

Wide format uv flatbed printer common machine failure and some solutions

Wide format uv flatbed printer breaks through the bottleneck of digital printing technology. It is a high-tech, free-form full-color digital printing machine that realizes a true printing, no plate making, full color image. Finished at once. It is not limited by any materials, and can meet the high quality and high requirements printing of many industries in metal, glass, leather, ceramics, wood, bamboo, cloth, T-shirt, plastic, silicone, MDF, PVC, acrylic, advertising materials, etc. demand. The color printing UV flatbed inkjet printer has been printed at one time, with rich and colorful colors, abrasion resistance, UV protection, simple and convenient operation, and fast printing image. The following are some of the faults that flat panel printers often see in daily use.

Wide Format UV Flatbed Printer 

1. UV flatbed printer nozzle blockage: The cause of the blockage of the UV inkjet printer nozzle is mostly due to the precipitation of impurities; partly because the acidity of the ink is too strong, corroding the nozzle. If it is because the printer has not been used for a long time or if non-original ink is added to cause the ink delivery system to be obstructed or the nozzle is clogged, it is best to clean the nozzle. If the problem cannot be solved by washing with water, the nozzle can only be taken down, immersed in pure water of about 50-60 ° C, cleaned with an ultrasonic cleaner, and dried after washing. The failure of the cleaning pump nozzle of the UV printer is also the main cause of the plugging. Cleaning the pump nozzle plays a decisive role in the protection of the printer nozzle. After the word car returns to the position, the nozzle should be weakly pumped by the cleaning pump nozzle to seal the nozzle. When the machine is equipped with a new ink cartridge or the nozzle is broken, the suction pump at the lower end of the machine is used to pump the nozzle. The higher the precision of the suction pump, the better. In actual operation, the performance and air tightness of the suction pump will decrease with time, and the amount of dust and ink remaining in the mouth will decrease. If the user does not
check or clean it frequently, it will cause the nozzle of the flatbed printer to continuously appear like a plug, so the suction pump should be maintained frequently. The specific method is to remove the upper cover of the UV printer and remove the trolley, and wash it with a pure water by a needle tube, especially to clean the microporous gasket embedded in the mouth. It should be noted that when cleaning this part, it must not be used with ethanol or methanol, which will cause the microporous gasket embedded in this assembly to dissolve and deform. At the same time, the lubricating oil cannot be touched to the pump nozzle part, because the grease will deform the rubber sealing ring at the pump nozzle portion and cannot seal the protection nozzle.

 UV Printer

2. The speed of UV flatbed printing machine is slow: after the continuous ink supply system is modified, the original ink cartridges will also be modified. This kind of transformation will inevitably cause the burden of the word car. In the case of heavy load, the word car will move slowly, the belt will accelerate aging and increase the friction between the car and the connecting rod. In severe cases, the word car cannot be reset and cannot be used.
To solve this problem, it is best to start from three aspects:
(1). Replace the motor, the hose of the continuous ink supply system of the flatbed printer and the wall of the UV printer are rubbed, resulting in increased load on the electric motor, and long-term use of the electric motor is very large. Replacing a new motor can solve the fault;
(2). Lubricate the connecting rod. After the printer has been used for a long time, the friction between the carriage and the connecting rod inside the machine becomes larger, and the increased resistance causes the electric motor to run slowly. Lubrication can solve the fault;
(3). Reduce the belt aging speed, and the frictional force of the driven gear connected with the motor accelerates the aging of the belt of the UV printer. The cleaning and lubrication of the driven gear can reduce the fault of the belt aging.

3. UV printers do not recognize ink cartridges: Users may often encounter this situation when using continuous ink supply: after using the flatbed printer for a period of time, the black ink cartridge cannot be recognized and will not be printed. The main reason for this situation is that the waste ink of the flatbed printer is already full. Because the waste ink is easily formed during the continuous ink supply system, it is easy to cause the waste ink to be full. This situation can be handled in two ways: First, use the clearing software to reset the UV inkjet printer motherboard to eliminate the printer settings; Second, replace the sponge in the waste ink tank at the maintenance point. However, it is recommended that the user adopt the second method, because if it is simply cleared, it is easy to cause the waste ink to leak and burn the flatbed printer. In fact, every uv printer's accessories have a fixed life. When some accessories reach the end of their life, the UV inkjet printer will prompt you to print.

Eco-solvent ink, what are the characteristics and how can we use it better?

Do you know what are the characteristics of eco-solvet inks? How can I use it better? This article will introduce you.

1. The characteristics of eco-solvent printing ink

(1).The fast drying of ink
The fast-drying characteristics of eco-solvent printer inks make it more important to

Eco-solvent Printing Ink

choose which printer to use. Piezoelectric printers are not so picky about ink, and it is the patent of Epson machine that often cleans the print head automatically.
(2). The main component of weak solvent ink is still organic solvent
The main component of the weak solvent ink is an organic solvent, which has a certain degree of corrosion and chemical reaction than the commonly used aqueous ink, so it is necessary to use a high quality ink manufacturer's product.

2.How to better use eco-solvent printing inks

(1). Due to some characteristics of the weak solvent ink itself, so the choice of supply
must be particularly careful. Some friends use weak solvent ink, the outer ink cartridge is leaking, the elbow connecting the ink line is blocked, and finally the print head is broken. So with a corrosion-resistant continuous supply or ink cartridges, especially desktop printers must pay attention to this. Do not use the equipment for a long time, pay attention to the cleaning of the nozzle part, so as to avoid the clogging of the nozzle due to the evaporation and solidification of the residual ink.
(2). Eco-solvent printing ink can be printed on some materials, or by printer heating, etc., but for some smooth surfaces, only ink is powerless, the ink will pile up together Can not be clearly imaged. Then you must use special coating liquid to match

Three advantages of using a coating:

a. The drying speed is fast, the coating is prepared with special chemical materials, and it is used together with the weak solvent ink. The printing is completed within one minute, especially on the smoother materials such as glass.

Eco-solvent Ink

b.The printing quality is good. It is not printed directly on some materials, mainly on
smooth and non-absorbent materials. The effect is poor, and the effect after coating is extraordinary.
c.Wear-resistant, waterproof Because of the adhesive component in the coating ingredients, the ink and material adsorption force is very close after printing, far exceeding the wear resistance of the uncoated state. Weak solvent inks have some advantages over all types of inks and are a wide range of products.

When using water-based sublimation inks ,Some things to be aware of it

When we use water-based sublimation inks in sublimation printing, we often ignore some of the problems. Sometimes these problems can make the printed images very poor and may even cause damage to the nozzles. Therefore, we cannot ignore these issues and we must pay attention to them. Here are some common questions and things to note.
1. When sublimation printing, pay attention to controlling the parameters of heat transfer sublimation ink, including ink viscosity, fluidity, thixotropic and plasticity.

Water-based Sublimation Ink

2. Pay attention to the control indicators of water-based ink. The control indicators of water-based inks mainly include fineness, viscosity, pH value and drying speed, which play a decisive role in the application of ink.
3. Since the aqueous ink is a pure aqueous system, care should be taken not to mix the aqueous ink with the alcohol ink and the solvent ink or to add an organic solvent to the ink to avoid printing quality problems.
4. When using water-based ink, it should be stirred evenly. After measuring the viscosity, pour it into the ink tank. If the viscosity is not suitable, adjust it with thinner or thickener, and pay attention to controlling the pH value of the ink. Generally, it is controlled at 8.5~ 9.5. During the printing process, due to the volatilization of water, the viscosity of the ink will increase and the pH will drop. Therefore, the use of the ink should be observed frequently. If the viscosity of the ink is increased or the pH is outside the control range, the diluent and pH stabilizer should be used in time. Adjust to ensure viscosity and pH stability.

5. Under normal circumstances, the sublimation printing ink is very suitable for high-speed printing. If the drying speed is too fast or the printing effect is not good during low-speed printing, a certain proportion of slow-drying agent can be added.

Why uv printer suddenly crashed druing work and how to solve it?

As a digital brushing device, uv printers will inevitably have small faults in operation. The size of the fault determines the service life of the machine. If a machine has a problem at two ends in three days, then the stability of the machine is not good enough. It can even be said that the manufacturer's technology is not in place and the quality of the product is not good. Today I will solve the common glitch of the uv machine and the solution to the uv printing machine crash.

 UV Printer

The uv printing machine crash is that the machine stops printing during the printing process and the software is out of control. In general, the crash can be divided into two types, one is a complete crash, that is, the uv inkjet printer and software all stop working; the other is a non-complete crash, mainly in the machine rail is running, but no ink, the printing process is interrupted.

The reason and solution for the uv inkjet printer crash:

1.External interference

Such as data transmission, computer configuration, USB cable, etc. will indirectly cause the tile background wall printer to crash, most of these cases are printing software crashes. Environmental problems can also cause certain interference. For example, if the air around the work is too dry and the static electricity is too large, it will cause the printer to freeze.

2.The printing software has failed

Printing fails, just like an application failure, we need to uninstall the existing printing software and reinstall it. You can try to reboot before reinstalling the printing software. If the printing software restarts and still freezes, it is recommended to reinstall. If the data is severely damaged, it is recommended to reinstall the computer system.

3.The machine itself is faulty

UV Printing Machine

The head of the uv inkjet printer is composed of guide rails and sliders. If the machine is used for a long time, it will inevitably wear out and malfunction. Customers are advised to check the rails, sliders, belts, screw rods and other accessories to ensure the integrity of the hardware.

Failure of the internal circuit system of the nozzle can also cause a crash. Internal circuit board failure is mainly caused by internal circuit damage or board burnout. Under normal circumstances, new machines are less likely to have such problems. Most of them are faults that occur when the machine is used for half a year or more. This part of the fault can be avoided in the usual maintenance.
If the large format uv printer crashes and the software factor is removed, it is recommended to immediately power off and contact the after-sales engineer for processing.

Sublimation transfer paper,what kind of wrapping paper packaging on it?

There are many types of wrapping paper packing of sublimation transfer paper , but the distinction between the functions used can be divided into three types of wrapping paper used in cartons, cartons, and paper bags.

1. Carton wrapping paper packaging: 

 Sublimation Paper

Carton wrapping paper is a packaging for packaging sublimation paper that we often see.. All kinds of carton boxes are made of this kind of wrapping paper, including calcium plastic corrugated boxes. Carton wrappers are made into die-cut boxes of various sizes through die-cutting, indentation, nail boxes or glue boxes, which are required throughout the packaging industry.

2. Carton wrapping paper packaging: 

There are many paper products in carton wrapping paper, such as medicine packaging box, silk packaging box, color gift packaging box, roof type milk packaging box, paper plastic color packaging box, etc. These boxes are very large. To a certain extent, it promotes landscaping products with its exquisite shape and decoration, and can enhance the propaganda of commodity brands in a subtle way. The shape and structure design of the carton is determined according to the shape characteristics of the product, so the style and type are various, including rectangular, square, polygonal, shaped carton, cylindrical shape and the like.

3. Paper wrapping paper packaging: 

 Sublimation Transfer Paper

There are many products in paper bag wrapping paper, such as commonly used portable shopping bags, food packaging bags, medicine bags, cement bags, feed bags, wax paper bags, fertilizer bags, laminated paper bags, four-layer paper bags and so on. They are all in the form of four kinds of paper bags, such as the edge of the bag, the bottom and the back cover. There are open bottom bags, open-bonded bottom bags, valve-type sewing bags, and valve-type flat hexagon end-end adhesive bags. Use four or more layers of paper to pack bags of cement, fertilizer and other products. Different paper bag types are used depending on the properties of the packaged object.

Which type of packaging you choose is related to the size of your heat transfer sublimation paper, and of course you can also pack it according to your requirements.

UV flatbed printer,How to distinguish whether it is second-hand or new printer

When we are ready to buy a uv flatbed printer, we must judge whether it is a new printer. If you spend money of new machine to buy an old printer, it will be too bad. Here are a few ways to share with you.

1. Date code.

Open the base of the UV inkjet printer nozzle and observe the internal accessories. Generally, there are date codes on the top. If the date of each component is very different, then the uv flatbed printer has been used for some time, and it has also been replaced by many components.

2. refurbished code

UV Flatbed Printer

The code posted on the print head is the same as the code on the software board. If it is not the same, then the uv printer is second-hand or refurbished. Because the new machine is absolutely the same.

3. Nozzle difference

The effect of the new print head printing is relatively poor when compared to the unused nozzles, because the nozzles will be better and better after a period of use. So when the two nozzles are compared together, you can pay attention. There is also the old nozzle, especially the nozzle that specializes in white ink. Be sure to pay attention to whether the nozzle passage is burnt out and whether the nozzle is blocked.

4. Whether the ink has traces of use

You can check the ink path, the ink tube, and the ink near the nozzle. If there is a description, the nozzle is used.

5. Head parts

UV Printer

The simple method is to look at the old and new parts of the UV flatbed printing machine head parts, open the head of the uv flatbed printing machine, observe the internal parts, the second-hand basic can be seen by the naked eye is old.
The above is a few ways to give some laymen a simple but not uv flatbed printing machine is a second-hand printer, I do not know if it will help you. In addition to the above methods, there may be better, you can also try. Thanks for browsing! Leave a message for me.

How to maintain large format digital inkjet printers when they stop working

If the large format digital inkjet printer is stopped for a long time, be sure to pay attention to the maintenance work of the nozzle, so as to ensure that the re-enablement after the holiday can quickly restore the normal use of the digital printer and maintain the high quality print output, and avoid the digital printer not being used for a long time. The nozzle is clogged, and the associated ink supply system is fluent and the machine equipment is malfunctioning.

 Large Format Digital Inkjet Printer

Therefore, before the holiday time, you should do the relevant pre-suspension maintenance of the digital inkjet printer, such as cleaning and moisturizing the nozzle, or if necessary, remove the nozzle to clean and wrap it, package it, and clean and place the surface of the digital printer. Dust-proof, disconnect the relevant power supply of the digital printer, close the relevant digital printer casing and place it well, pay attention to the environment to prevent rat damage. These are all good maintenance work after the digital printer is stopped before the fake.
In order to better maintain the digital printer, if the digital printer is not used for a long time, the following maintenance should be carried out on the digital printer and the piezoelectric nozzle to prevent the nozzle from being clogged and other related digital printers from malfunctioning.
First of all, according to the length of the holiday time, the wide format digital printer normal shutdown of the time is not long, you can power off, the time is too long (outdoors more than 4 days in the house for more than 8 days, experienced can also decide according to their own experience) to remove the nozzle, Store it. First remove the nozzle, remember that the nozzle mirror (ink ejection surface) does not touch anything. When removing, first remove the ink bag, then remove the ink bag holder, then remove the three screws of the fixed nozzle, then take the nozzle out smoothly and remove the two data lines. Pay attention to the ink when removing it. Do not put the ink on the top of the nozzle for the next cleaning. (As shown below) After removing the nozzle, ensure that the cleaning solution is not

contaminated by dust (oily cleaning solution for outdoor nozzle, water-based cleaning solution for indoor nozzle), and clean the supplied syringe. (Note the inside of the glass syringe.) Do not have impurities). Comes with a silicone tube with a length of ten centimeters. Please pay attention to ensure that there are no impurities inside the tube before use. Be careful to block the nozzle.
When cleaning, connect the silicone tube to the syringe, draw the cleaning solution into the syringe, and connect the other end of the tube to the eight ink-injecting columns of the nozzle one by one, then gently push the cleaning solution into the nozzle, and then the cleaning solution from the nozzle. Below the mirror nozzle, please note: (Do not use too much force to avoid damage to the nozzle) Please pay attention to the following points when cleaning:
1. During the cleaning process, be careful not to flow the cleaning solution into the data line chip of the plug nozzle, and tilt the other end as much as possible to avoid the inflow of the cleaning solution.
2. Pushing the syringe too hard during cleaning will cause the tube connected to the nozzle to spring open. When cleaning, press the nozzle and silicone tube connection to avoid unnecessary trouble.
3. After cleaning, the mirror surface will have residual ink on the bottom of the nozzle. You can use a clean container to pour the cleaning solution into the container (the oily cleaning solution is corrosive, be careful that the container will be perforated and leak), soak the mirror surface of the nozzle in the cleaning solution. (Note: just immerse the mirror in the inside, the other parts do not need to be soaked, but the mirror surface should not be in contact with the bottom of the container, only the immersion time in the cleaning solution can be immersed in the cleaning solution for about 1--2 hours.)

Inkjet Digital Printer

4. After the soaking, remove the nozzle and wipe off the residual cleaning solution and ink of all parts except the mirror surface. Pay attention to the mirror surface. After cleaning, you can use a plastic wrap to seal it (if you have a moisturizing solution, please inject it into the moisturizing liquid). Do not entangle it when wrapping. Do not bump the mirror after wrapping. When storing, the nozzle should be placed obliquely. Do not directly place the mirror on the table.
Note: There is also a simple method for using the cleaning solution as ink, and continuously pumping ink until the ink path and the nozzle are cleaned.
It is vital to maintain your digital printing machine in daily life.

When sublimation printing,is it correct that the pure black CMYK value you used?

In the sublimation printing, sometimes the black C, M, Y, K are set, sometimes the output of the printer color, sometimes the setting of the file image mode, and sometimes the color of the ink. Do you know how to judge the pure black C, M, Y, K values is correct? Here are some tips to help you.

1-CMYK value is wrong

Sublimation Printer

Large-scale color inkjet printing devices such as piezoelectric photo printers and inkjet sublimation printers are usually output in CMYK four-color or CMYK LC LM six-color color. Piezoelectric photo machines are mostly CMYK four-color color output solutions. Therefore, to output black, it is necessary to pay attention to the setting of color and color values.
Whether it is a printed image or a photo image, there is a single black value. Many new debut designers, with little practical experience, can easily set the black value of the inkjet print to the following values: C0, M0, Y0, K100. The effect of this color value inkjet printing must be gray-black, and many times, the screen still has There will be a light gray cross section in the black part, which affects the overall effect. Some designers also use the color values of C100, M100, Y100, and K100. The effect of inkjet or photo rendering is too dark, not easy to dry, and the picture is easy to spend.
The correct black and black value is: C=50 M=50 Y=50 K=100.

2-File image mode is wrong

The image file color mode problem saved by the inkjet photo image will also affect the black color of the sublimation transfer printing. Therefore, when designing the advertising image, please set the file to CMYK image mode, and the inkjet requires CMYK mode. The inkjet software uses the four-color type of CMYK, be careful not to use RGB mode.

3-ink problem

Sublimation Printing

The last point to note is that in addition to the CMYK settings, the quality of the dye sublimation ink also affects the color reproduction. Be sure to use the original ink of the photo machine manufacturer, in order to more effectively ensure the correct ink curve and the best color reproduction.
