Micronized waxes have good lubricating properties and can reduce the friction of inks during the printing process, thus improving the abrasion and scratch resistance of inks. For example, in water-based inks, the wax powder can prevent printed materials from sticking to each other when stacking, especially in high temperature environment, this property is especially important. Micronized wax can be used as a matting agent to reduce the gloss of the ink by the distribution of its particles on the surface of the ink, so that the printed matter has a matte effect. Micronized wax can be evenly distributed in the ink to improve the smoothness and feel of the coating. At the same time, it can also enhance the dispersion of pigment, so that the pigment coloring strength is increased. In oil-based ink, micronized wax can form a wetting film on the ink surface, making the ink surface smoother, more even and flat.
