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.

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!
