(Summary description)Dye ink (Dye Ink) is a molecular-level fully soluble ink. This ink is a complete composite solution. The probability of blocking the ink head is very small. After printing, it is easily absorbed by the material. The color is bright and the cost is low.

The disadvantage is that it is not waterproof, and because the dye molecules are quickly decomposed under ultraviolet light, the color will fade significantly within one month of outdoor use under ultraviolet light.

The advantage is that the color is bright, the level is clear, and the price is lower than that of the pigment ink, so it is the first choice for printing pictures and making color-jet business cards.

Pigment ink (Pigment Ink) is a vivid description, it is powder ink, of course, this is only a vivid statement, not accurate enough. To be precise, it grinds solid pigments into very fine particles and dissolves them in a special water solvent. It is a suspension or semi-solution, which has the same properties as the pigments used in printing and dyeing clothes. Contrary to the principle that the dye ink penetrates into the medium to form color, it develops color by attaching the color material to the surface of the medium (such as copy paper or printing paper, etc.).

Therefore, its advantage is that it is printed with pigment ink, even if it is printed on ordinary paper, it will not bleed, and because the pigment itself is waterproof and not easily decomposed by ultraviolet rays, it has strong water resistance and light resistance. Even when used outdoors, it can be maintained for more than one year without obvious signs of fading.

The disadvantage is that most of the pigment ink will leave the color material on the surface, so even if it is printed on glossy paper and other flat-surface paper, it cannot print a glossy image. This is why it is generally printed with pigment ink. The things are not shiny. In addition, the manufacturing cost of pigment ink is higher, so the price is more expensive than dye ink, and the price difference is as high as two to four times or more.
