Before I buy the inkjet sublimation paper,how can I test its quality?

 Inkjet Sublimation Paper

Digital textiles is a family, among which sublimation is an important member, composed of three important roles: thermal sublimation printer, sublimation ink and sublimation transfer paper. They stick tightly to each other and cannot work without any of them, like triangles.

Because many people do not know exactly how to test the dye sublimation paper samples and fully identify the quality of sublimation transfer paper. Our production workers and researchers offer the following tips based on their expertise.

First, you should know your sublimation transfer paper test report.

Check the test report of sublimation transfer paper provided by supplier. The test report is conducted by the researcher in the original laboratory, including every important factor of the paper, and all the data are authoritative and reliable.

Second, check the paper's appearance.

1. Smoothness of paper

Sublimation Paper

Smoothness can be easily identified by observing the surface of sublimation transfer paper roll. Using high quality sublimation transfer paper, the printing surface is very smooth. Because if the printing surface is too rough, it will scratch the high precision piezoelectric print head. Our sublimation coating is very good to ensure the optimum smoothness of the paper.

2. The Impurity

Check the paper for any dots. When you transmit a solid color (just one color), the dot can seriously affect the transmission result.

Third, test the paper on your device

Drying time: when printing paper, you can see the drying time of heat transfer sublimation paper.

(1). Drying paper quickly can greatly improve your productivity.

(2). High transfer. This is very important. Transfer efficiency is, first, how much ink the paper can transfer to the fabric during the transfer process, and second, color restoration. According to our test, our high quality paper transfer rate is 97.6% and viscous sublimated paper is 96.4%.

The final test results are related to your printer and ink, and when you first test the paper and the results are not ideal, you'd better adjust the print and transfer Settings based on the sample.

Can heat transfer sublimation paper be used to print dark fabric?

 Heat Transfer Sublimation Paper

Printing dark fabrics on heat transfer sublimation paper successfully and easily is probably one of the holy grails of garment decoration, and decorators are always searching for new solutions.One of the questions we get asked quite often is whether or not sublimation can be done on dark fabrics. Since sublimation has a lower cost for entry than other forms of printing,  many people are eager to sublimate on light and dark fabrics but,  as of right now,  it doesn’t work that way.  Sublimation can only be done on light colored polyester fabrics or poly coated items.
There are two reasons that sublimation paper doesn’t work on dark colors.  The first is that sublimation ink dyes the fibers of the garment.   Sublimation is a process by which a solid turns into a gas without going through a liquid state.  Through the use of heat,  the gas bonds with the fibers of the garment,  or the poly fibers in the coating on the sublimation blank,  and dyes those fibers.  There is no coating and no underbase,  the ink literally dyes the fibers and becomes part of the fabric.  Using this process on darker fabrics doesn’t work because,  although you can dye the darker fabrics with the ink,  you won’t be able to see the resulting design.

 Sublimation Paper

The second reason that sublimation won’t work with dark colors is the lack of a white underbase to make the colors stand out.  Any type of printing that is even moderately successful with dark colors, whether it’s screenprint or direct to garment printing,  requires laying down an underbase of white before the colors are applied.   Sublimation ink only works on polyester,  so laying down an undercoat of white would require something that had polyester fibers in it,  which may not even be possible when it comes to ink.
Currently,dye sublimation paper only works with lighter colors.   It is recommended primarily for white,  as white will not interfere with the colors of the ink.   If you do choose to sublimate on a light color,  please understand that the color of the fabric will have an impact on the color of your ink.Oftentimes the tone on tone color contrasts are attractive,  but the fact that garment color can alter ink color slightly should be kept in mind.

Dye sublimation paper absorbs ink properties, do you know what factors affect it?

The dye sublimation paper is a type of heat transfer printing paper which functions as a carrier during the transfer of the pattern. The sublimation transfer printing first uses special inkjet printing to print a special printing dye (ink) onto the transfer paper, and then the transfer paper printed with the pattern and pattern is in close contact with the fabric, and the transfer printing is performed at 200~230 °C. The machine is processed for 10~30s, and the dye is transferred from the printing paper to the fabric, and diffused into the interior of the fabric to achieve the purpose of coloring.
Sublimation transfer printing prints images on paper through high-speed, high-quality inkjet printers, eliminating the need for plate making, replacing screen
printing, and the patterns can be scanned by computer or scanning instruments, which is convenient, precise and easy to adjust. At the same time, the transfer pattern is clear, realistic, and the authenticity rate is high. The image is not easy to fade, fall off, and has a long service life. The printed product is soft and comfortable, and is more and more popular.

 Dye Sublimation Paper

It is precisely because of its excellent performance that the digital sublimation paper must meet various requirements, such as high temperature resistance, shape stability and ink absorption, etc., especially the ink absorption performance has a sublimation inkjet paper. Great impact. The ink absorption of the base paper is too strong. If the ink absorption is too fast, it will cause bleed, and the ink absorption is too weak. If the ink absorption is too slow, the ink accumulation phenomenon will occur. These two phenomena will affect the thermal sublimation transfer. The performance of the paper, which in turn affects the transfer effect. Therefore, it is necessary to discuss the influencing factors of the ink absorption performance of the sublimation printing paper.

1. Influence of ink viscosity on ink absorption performance 

The ink absorbing performance is not only related to the structure of the inkjet sublimation paper, but also to the viscosity of the ink itself. The viscosity of the ink is too small, the penetration is strong, and it is easy to penetrate the paper to produce a tinge phenomenon; the viscosity of the ink is too large, the penetration is weak, and it is easy to accumulate on the surface of the paper to produce a pile of ink. Both twilight and ink accumulation can have a serious impact on the transfer effect of the product, and such phenomena must be prevented during the production process. Specifically, the process parameters of printing pressure, temperature and time can be combined to determine the viscosity of the ink to ensure the printing quality of the pattern.

2. Influence of paper surface coating on ink absorption performance 

Since the production process of the sublimation transfer paper is subjected to a high temperature environment, the strength performance of the paper is greatly lost, so it is necessary to increase the speed of inkjet printing and drying, and shorten the time the paper stays in a high temperature environment, so as to retain the sublimation as much as possible. The strength properties of the transfer paper meet the requirements of the product. This puts higher requirements on the ink absorbing performance of the paper. Under the condition of ensuring a certain amount of ink absorption, it is necessary to enhance the ink absorbing performance of the paper and increase the ink absorbing speed of the paper.
To this end, a layer of paint is applied to the surface of the paper as a coating to achieve rapid ink absorption. In order to meet the requirements of the national environmental protection policy, the inks currently used for the production of sublimation transfer paper are mostly water-based inks. Most of the ink components are alcohols and polyamide compounds. In order to ensure the quality of the transfer pattern, it is required that the surface coating layer does not contain a component capable of reacting with the ink used, and the coating of the surface coating layer is usually made of silicone or polyvinyl acid.

3. Influence of paper structure on ink absorption performance

The ink absorption of paper refers to the ability of the paper surface to receive the

 Sublimation Paper

transfer ink at the moment of imprinting, the ability of the paper surface to be wetted by the printing ink, the ability of the paper surface to absorb certain ink components, and the ability of the paper surface to fix and retain a uniform ink film. The comprehensive embodiment. Paper absorption ink is divided into two stages, one is the pressure infiltration stage: at the moment of printing press imprinting, depending on the printing pressure, part of the ink transferred to the surface of the paper, including pigments, binders, etc., is simultaneously pressed into the paper. In the pores. The second is the stage of free penetration. This stage is from the paper leaving the embossing area until the ink is completely dry, mainly relying on the capillary action of the paper fibers to absorb the ink. At this stage, the absorption rate of the ink on the paper determines whether the printed matter has gloss, and whether powdering or offsetting occurs.

Paper is a porous material with a large number of small gaps or pores inside the paper. If the paper's pore structure and ink characteristics do not match, it will lead to a series of printing failures. When the pores between the paper fibers are small, the capillary action of the fibers is destroyed, the ink absorption performance will be poor, and when the pores are large, the ink absorption of the paper is too strong, and if the ink used at this time is low in viscosity, When the printing pressure is large, the ink will penetrate into the back of the paper, and the offset phenomenon will occur, so that the print cannot exhibit the desired color saturation on the surface of the paper, which affects the quality of the printed matter.

In addition to the basic requirements of general coated sublimation paper, the base paper of the sublimation transfer paper has certain requirements on the tightness and air permeability of the base paper. The base paper has a tighter degree,generally above 0.9g/cm3, and the air permeability is smaller. If the base paper is too tight and has a large air permeability, the ink will penetrate into the back side of the base paper during the inkjet process, causing a bleed phenomenon. During the sublimation transfer process, the sublimated ink will also spread out through the back side of the base paper. , affecting the transfer effect. If the base paper is too tight and the air permeability is small, in the inkjet process, the ink does not easily enter the inside of the paper, accumulates on the surface of the paper, is easily smeared, and causes ink accumulation, which also affects the transfer effect. The ink absorption performance of the sublimation transfer paper base paper is also closely related to the paper void ratio, the filling amount, the sizing amount, etc., and the void ratio is a fundamental factor affecting the ink absorbing performance of the paper, and the ink particles enter the paper inside through the gaps. 

The size of the void ratio directly affects the speed at which the paper absorbs ink and the amount of ink absorbed. The amount of filling will affect the void ratio of the paper, which will affect the ink absorption performance of the paper. The type of filler will be different, and the affinity for the ink will be different, which will also affect the ink absorption performance of the paper. Whether it is in-sizing or in-slurry sizing, it will affect the hydrophilicity of the paper, which will affect the absorption of ink by the paper.

4. Influence of other factors on the ink absorption performance

In addition to the above factors, the ink absorbing performance of the heat transfer sublimation paper is closely related to the moisture content of the paper, the pressure during printing, the temperature, the time, and the like. The paper fiber is a hydrophilic substance. When the water content of the paper is high, a hydration layer is formed on the surface, which is disadvantageous for the ink binder to be combined with the fiber, and even affects the penetration of the binder, so that the absorption of the ink by the paper is lowered. Especially for oily inks with water repellency, this effect is more prominent. At the same time, the presence of the hydration layer also hinders the absorption of oxygen by the paper, delaying the process of oxidative polymerization of the ink, which is extremely disadvantageous for the absorption of ink on the paper sheet (especially the oxidized conjunctival drying type ink). Therefore, the water content of printing paper should not be too high. Taking into account other factors, the moisture content of the paper before printing is generally controlled at 4% to 8%. In addition, the printing pressure, temperature and time will also affect the ink absorption performance of the sublimation transfer paper. The printing pressure directly affects the pressure infiltration phase of the paper absorption. The temperature affects the viscosity of the ink and the drying speed of the ink. It also affects the length of pressure and temperature contact with the paper. In the actual production process, these factors must be comprehensively considered, and the production and printing process parameters should be reasonably determined to obtain qualified sublimation transfer paper.

Digital textile sublimation paper,do you know the reason why it appears flawed

The flawed of digital textile sublimation paper may be related to the machine and may be related to the paper formula. Do you know what causes it?

Digital Textile Sublimation Paper

1. The stencil connector of heat transfer sublimation paper is bad (printing). The pattern at the flower splicing plate overlaps or does not match (disengage). Due to poor adjustment of the conveyor belt or improper adjustment of the Taiwan version of the rules, affecting the accuracy of the flower position.
2. Dew white. A part of the warp or weft yarn is turned over or moved to the front and back of the fabric, and the pattern appears to be traced after being scratched. Most of the rickets are caused by poor penetration of the color paste and improper handling after printing (uneven tension, etc.).
3. The wrong position of the version (set, set is not allowed) is a printed product with a misplaced pattern. Most of them occur when the flowers are not accurate, the carving is poor, and the stickers are bad. The reason why the sublimation paper is defective.
4. The frame mark (frame print, detachment) printed part shows the abnormal streak of the shape of the flower frame. Mostly due to poor conveyor belt, poor installation of the stencil frame and other reasons.
5. A part of the printing unevenness (spot) print becomes a spot like the shape of the skin of the sand fish. The rickets often occur when the viscosity of the color paste is not appropriate, the mesh mesh is improperly selected, or the patch is uneven.

Jumbo Roll Sublimation Paper

6. Inkjet sublimation Paper bending (flower-shaped skew) means that the warp and weft yarns of the fabric are inclined or curved. This usually occurs when the printed fabric (silk) itself has a weft or a poor seam or a skew of the platen.
7. The color of the bleed (opening) print pattern oozes out, the outline of the pattern is not clear, and the color is blurred. It is caused by low viscosity of the color paste, extremely concentrated dye concentration, excessive amount of printing and suction, and a large amount of moisture absorbent.

How to deal with digital sublimation paper absorb water unevenness in different humidity environment

Sublimation printing needs to be carried out under a certain humidity environment. The degree of drying of the digital sublimation paper is the key to the success of the sublimation pattern printing. When encountering the following different humidity environments, please solve the problem according to the situation.

Digital Sublimation Paper

1.The humidity of the printing environment is best controlled at 45~ 70% RH, such as the air is too dry easy to make the heat transfer sublimation paper warp, when the ink transfer film elongation and arch may cause friction nozzle failure; For example, too wet air will lead to transfer paper ends of the drying speed and elongation reduction. Please install and turn on the air conditioner in the inkjet printing room. The inkjet printing can be stabilized under stable environmental conditions. If there is no air conditioning constant temperature and humidity, the solution is to take out the transfer paper 1-2 days before printing plastic bags, the paper is exposed to the air, balance the moisture transfer of the paper, the purpose of this is to transfer printing paper absorb water and pre-stretch, in order to avoid too much transfer paper can not absorb the printing ink and elongate the arch.
2.When the environment humidity is very large, because the water is not evenly on both sides, the base paper layer of transfer paper may not be consistent, in this case the elongated design will be skewed or stuck, and can be placed remedial measures between the feeding side and unwinding roller have a clean steel pipe, in the pipe ends of a proper weight and keep the transfer paper smooth and proper tension.
3.When the sublimation transfer paper absorbs too much water in the air, the paper becomes very soft, so it is easy to pick up the paper roll wrinkle. The solution is to remove some paper picking wheels, reducing the force to keep the printer flat.
4.In order to confirm the printing surface of the transfer paper, the printing surface of the full roll of paper is super external. When the printing surface cannot be determined, fingers can be stained with water respectively. Heavy is the printing surface of the transfer paper on both sides.
5.When placing transfer paper on the printer, take a muslin glove to prevent the paper from getting dirty.
6.In the case of a new reel, it is safe to print a small piece of standard color (standard color is a common pattern made up of four or six colors familiar to the user by CMYK) and perform transfer tests to ensure that each color scrolls the same color. If obvious color appears, find out the reason and eliminate it in time.

Sublimation Paper

7.In the printing process to do test dye sublimation paper, ensure that the nozzle ink smooth, make the pattern color consistent, avoid local nozzle blockage and printing defects.
8.Print printer's built-in heater and set the appropriate temperature, or turn on the external air drying equipment, print the ink volume on the printing surface when printing. Make sure that the scrolling process does not stain the back of the print to avoid defects.

How to Remove Excess Sublimation Printing Ink From Ink Cartridge Without Damaging Printer

When we print the picture, there will always be the remaining sublimation printing ink. Do you know how to remove it from the ink cartridge without harming the printer?

Sublimation Printing Ink

First of all, we should return to the initial position of the printer ink cartridge, then take out the waste dye sublimation ink tube from the waste ink bottle, insert the waste ink nozzle with a 50ML syringe, and force the syringe backward until the waste ink extraction is completed, and insert the waste ink tube into the waste ink bottle after the extraction. It should be noted here that when drawing out the waste ink to pull back, waiting for no back force to release the hand, pumping can not immediately pull out the syringe.
In the extraction of waste ink, must pay attention to the following three conditions:
1.When drawing out the waste dye sublimation ink, if it is found that there is oil leakage, do not waste ink, should be careful, that the universal printer cleaning system is a problem, need to replace the nozzle protector to solve.
2.If there is water leakage in the process of ink pumping and waste ink, it indicates that the ink sac of universal flat plate printer is damaged and cannot be used normally, and a new ink sac needs to be replaced.
3.Every time after cleaning the flat plate printer to extract waste ink, must be clean, so as not to cause "siphon" phenomenon, causing unnecessary loss of ink cartridge and the pollution of the whole ink system.

Sublimation Ink

Customers in the universal printer to extract waste sublimation transfer ink, be sure to follow the correct steps to operate, so as not to damage the second inkjet printer. Novice purchase of inkjet printer, operation, be sure to follow the instructions or technical professional training say operation steps, in order to avoid failure, damage inkjet machine. In the printer failure, encountered their own can not solve the problem, be sure to find a manufacturer of technical guidance for operation, do not dismantle their own printer.

Fast Dry VS Sticky Sublimation Paper-Why Does Former Drying Time Faster Than Latter?

When you are using sublimation paper, you usually encounter sticky sublimation paper drying time longer than fast dry sublimation paper, which will affect the use of paper, the following reasons will tell you.

Sticky Sublimation Paper

Tacky sublimation paper is a kind of sublimation dye paper, and the main difference between the normal sublimation digital paper is that it has a sticky coating. The sticky coating can adhere to the textiles very firmly, and it can help the paper and textiles not moving during the sublimation printing.

The sticky sublimation textile paper is mainly applied to stretch materials like Lycra, polyester with spandex, polyester with cotton(<30%). There are many advantages of sticky sublimation digital paper, such as high transfer rate, good drying time, sharp text and fine lines as there is no movement between paper and fabric. But many people are puzzled one problem that why the sticky/tacky sublimation paper dries slower than regular sublimation transfer paper, even though the sticky paper is quick-dry type as well. This doesn't mean the sticky paper has quality problem.

The coating of the sticky sublimation dye paper is the main factor that can influence the speed of drying. The coating of sticky sublimation textile paper is mainly made up of high molecular polymer. Different with the fast dry sublimation transfer paper, this kind of coating is water-based, so the sticky paper needs longer drying time. And there is one thing that you should know: the higher tackiness is, the slower the paper dries. You should choose the suitable sticky paper instead of higher sticky paper.

Different factories and customers have different requirements about the sticky inkjet sublimation paper. Some of them pay more attention to the tackiness of the paper, because they just want high sticky paper, and don’t care the drying speed. But some factories and customers just put a little sticky coating onto the paper to improve some performance of the regular paper. 

 Fast Dry Sublimation Paper

So you should choose the corresponding dye sublimation paper according to the material you want to use, instead of choosing fast drying time.
