Introduction
PN-PDT paper dirt tester is made according to GB/T154l 《Paper and board-Determination of dirt》.The degree of dirt is the number of dirt with a certain area per square meter of paper and cardboard, or the equivalent area (mm2) of dust on paper and cardboard per square meter. Dust is a kind 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.
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.
