Printer pigment ink experience
Pigment ink chemical stability and optical stability, water resistance and light resistance, and high security, print color sharpness and high density. Although the water will penetrate the paper when printing, but the pigment is adsorbed by the paper and no longer dispersed in the water, will remain on the surface of the paper to form a stacking layer, hiding power, the requirements of the paper to reduce, so to achieve high density and high Sharpness of the print.
In other words, the first solid pigment grinding into very small particles, dissolved in a special water solvent. And dye ink into the media to form the principle of color exactly the opposite, it is attached to the media through the color of the surface to the hair color.
The colorant of the pigment ink is a pigment that is insoluble in water and is suspended in water by means of a dispersant, so it is an opaque liquid.
The ink is more easily washed away later, the water-based pigment ink is half-solution, it is not suitable for swellable photo paper and cast coated paper, are generally used in the gap type RC waterproof paper above.
