When it comes to inkjet printers, we have to talk about ink, because ink affects the quality of printing and also affects the printing cost of users. These are the issues that users are most concerned about, but when buying ink, they will I found that there are two options for pigment ink and dye ink. Is it to choose pigment ink or dye ink? What is the difference between pigment ink and dye ink?

Dye ink [2] 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. 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. However, because of its bright colors, clear layers and lower price than pigment inks, it is the first choice for printing pictures and making color-jet business cards.

Pigment ink is more vivid than powder ink. Of course, this is just a vivid statement and is 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 suspended solution 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, printing with pigment ink will not bleed even when printing on plain paper, and because the pigment itself is waterproof and not easily decomposed by ultraviolet rays, it has strong water resistance and light resistance. The printed matter can even be outdoors. It can be used for more than one year without obvious signs of fading. However, most pigment inks will leave color material on the surface, so even if you print on glossy paper or other flat-surface paper, you cannot print a glossy image. This is why pigment inks are generally used for printing. The thing is 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. In view of the above factors, pigment ink is mainly used for outdoor inkjet printing, and personal users rarely use it.

Pigment ink is better than dye ink in water resistance, light resistance and corrosion resistance, while dye ink is stronger than pigment ink in friction resistance and color rendering, so the choice of ink depends on actual needs. Generally speaking, the price and performance of pigment inks are higher than that of dye inks, and the use of pigment inks is also the development trend of various ink manufacturers.
