Once the paper has static electricity, it will bring a lot of trouble to printing. The first is that the paper does not collide. Under the action of static electricity, the paper is firmly absorbed and uneven between the paper, the air is difficult to enter the paper, and sometimes it is a waste of time to open it by hand. In the printing process, due to electrostatic attraction, the sheets of paper are firmly pasted together, sometimes two, sometimes several, and sometimes a stack of paper can not be separated, resulting in the paper suction mouth can not absorb the paper. When the brush is pressed heavily, it often produces broken tension and empty tension. The brush press light, and produce double, multiple. Multiple sheets of paper entering between the rubber drum and the embossing drum will cause congestion and crush the rubber cloth and liner. The paper with static electricity is not smooth when it is transported forward on the paper feed table, and the skew and positioning are not correct when reaching the former gauge, resulting in the failure to register the second overprint, poor product quality and great waste. Even after the stamping part, the receiving paper is very uneven, which brings great trouble to the second whole paper and seriously affects the production speed.

pop up book manufacturer has something to do with paper making. Under normal circumstances, the base paper is less charged when leaving the factory, and the probability of coated paper being charged is not large. Because printing paper (whiteboard, cardboard, etc.) and coated paper are reprocessed on the basis of base paper, even if the base paper has been charged, it will be eliminated during processing. Generally, there are more pop up book manufacturers with a quantity below 80g/m2, but the paper machine has static electricity before printing or static electricity is not obvious, and it is often a sudden increase of static electricity after embossing. Due to water in the offset printing process, it is generally rare to have static electricity after printing, for offset printing, static electricity is mainly generated before printing.
