1、 The roller pressure should be adjusted properly for food packaging bag printing. If the ink color is too heavy and the solid bottom is too large, it is easy to stick rubber or ink roller. Therefore, before printing to reduce the pressure of the drum, rubber lining to reduce. In order to avoid sticking rubber, rolling rubber, to the ink to add some additives or track adhesive, at the same time, to avoid double sheet, multi sheet and paper skew, to ensure that the pressure is uniform, do not roll rubber.

2、 Food packaging bag printing, like other prints, needs to be accurate, otherwise it will affect its quality. When printing, it is necessary to adjust the height of the front gauge and side gauge pressboard according to the paper thickness, and at the same time, adjust the pressure of the paper pressing wheel and brush wheel on the paper conveying board, and tighten the loose paper feeding cloth belt. 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.
3、 Ink color has a direct impact on the quality of printed matter, while packaging plays an important role in protecting and decorating articles. The quality of packaging and printing will directly affect people's aesthetic outlook and consumption. Therefore, when printing packaging, must conform to the quality standard. To complete exquisite and beautiful products, we need to carefully complete every step of the printing work, so as to have considerable profits and quality.
