1. Food packaging bag printing, like other prints, needs to be accurate, otherwise it will affect its quality. When printing, the height of front gauge and side gauge pressboard should be adjusted according to the paper thickness. At the same time, the pressure of the presser wheel and brush wheel on the paper feeding board should be adjusted. The loose paper feeding belt should be tightened. When starting the machine, if you find that the rules are not good, you should check the paper feeding situation and the pressure of the paper wheel and the pressure wheel in time; for thicker paper, the pressure of the paper pressing wheel and the brush wheel should be heavier. And the paper time and pull gauge time, as well as the side gauge and swing teeth hand over time, found problems in time to deal with, until up and down and left and right rules are accurate without error.

Therefore, before printing to reduce the pressure of the drum, rubber lining to reduce. In order to avoid rubber, rubber rolling, to add more additives or adhesive to the ink, at the same time, avoid double sheet, multi sheet and paper skew, ensure that the pressure is uniform, not rubber rolling.
