Significance<\/h2>\n

Dust is a type of defect of paper appearance, which can be inspected by eye, hand, and nose. It is impurities such as black, yellow, dark yellow, yellow brown, or brown dots that are significantly different from the color of the paper.<\/p>\n

A high degree of dirt will reduce the printing quality. In the printing of coated paper, cardboard, and white cardboard, especially in color printing, the effect of the degree of dust is particularly obvious, affecting the printing quality.<\/p>\n
