HOW TO DISTINGUISH BETWEEN THERMAL TRANSFER INK, DYE INK AND PIGMENT INK?

Thermal transfer ink is also called sublimation ink, which is mainly used for heat transfer printing products. The thermal transfer ink can be printed on other products after being heated by the heat transfer machine, so it is one of the essential materials in the thermal transfer industr and mainly used in non-cotton materials.

 

 

1.Compared with other dye inks, pigment inks and water-based inks, thermal transfer inks are bright and dense, and have high density. Thermal transfer inks are mainly produced in the United States and South Korea, and American heat transfer inks and Korean heat transfer. The ink color is fresh and thick, and the American thermal transfer ink printed on paper and the Korean thermal transfer ink pattern are light and clear. After heat transfer by the heat transfer machine, the image is clear and the color reproduction degree is high. It is also the advantage of import thermal transfer ink printing.

 

2.Dye ink is a molecular-level fully dissolved ink. This ink is a complete composite solution. The probability of blocking the ink head is very small. It is easy to be absorbed by the material after printing, and the color is gorgeous. Moreover, the cost of manufacture is low, and the disadvantage is that it is not waterproof, and since the dye molecules are rapidly decomposed under ultraviolet irradiation, the use of outdoor ultraviolet rays is markedly faded within one month. The advantage is that the color is bright, the layer is clear and the price is lower than the pigment type ink, so it is the first choice for printing pictures and making color inkjet cards.

 

 

3.The pigment ink said that the image point is powdery ink, of course, this is just a kind of image, and is not accurate enough. To be precise, it is a solid pigment that is ground into very fine particles and dissolved in a special aqueous solvent. It is a suspension solution or a semi-solution, which is the same as the pigment of our dyed clothing. Contrary to the principle that dye ink penetrates into the medium to form a color, it is colored by the color material attached to the surface of a medium such as copy paper or printing paper.

 

Therefore, it has the advantage of printing with pigment ink, even if it is printed on plain paper, it will not smear, and because the pigment itself is waterproof, it is not easily decomposed by ultraviolet rays, so its water resistance is strong, it is also light-resistant, and printed matter Even if used outdoors, it can last for more than a year without obvious signs of fading.

 

The disadvantage is that most of the pigment inks will leave the color material on the surface, so even if you print on paper with a flat surface such as glossy paper, you can't print a glossy image, which is why it is usually printed with pigment ink. The things are all dull. In addition, pigment inks are more expensive to manufacture, so the price is also higher than that of dye inks. The price difference is as high as two to four times. The thermal transfer images are brightly colored and rich in layers. The effect is comparable to printing. The difference is that Thermal transfer is an image that can be formed by sublimating a thermal transfer ink at a high temperature, penetrating the surface of the medium, and desubliming. Therefore, a film is not formed on the surface of the medium, and the image does not fall off, is not cracked, and is light-resistant, and does not fade for a long time.
