First, the difference between inkjet printing ink and ordinary printing paste
1. The amount of ink applied by ink jet printing is small and the color rendering is high;
2. The ink used for inkjet printing is generally 6-8 colors;
3, inkjet printing ink should have excellent anti-precipitation, can not have any particles, impurities, excellent color fastness, stable color;
4, inkjet printing ink can not be mixed with other printing chemicals.
The colorants are mainly dyes, which are active, acidic, and dispersed. They are used for the printing of cotton, silk, nylon, and polyester fabrics, respectively.
Second, inkjet printing colorant / color material
The color used for ink jet printing is printed on paper, and it is generally four kinds of CMYK (Cyan Cyan, Magenta Magenta, Yellow Yellow, and BlacK Black). In order to increase the printing speed, the number of colors can be increased.
1. Dyes: According to fiber properties, high purity active, acid, dispersion and other dyes can be used;
2, pigments: wide applicability, but its insoluble particles can easily cause nozzle clogging, especially in the DOD system; Another problem is that when printing high color concentration, you must add more pigment in the ink, make the viscosity increase, It is difficult to use in printing.
