In order to avoid sticking rubber and rolling rubber, add more additives or auxiliaries to the ink. At the same time, be optimistic about avoiding double sheets, multiple sheets, and paper skew, and ensure that the pressure is not even when the rubber is rolled.

Two: The printing of food packaging bags, like other printed products, requires that the rules be accurate, otherwise it will affect its quality. When printing, adjust the height of the front gauge and the height of the side pressure plate according to the thickness of the paper, adjust the pressure of the paper roller and the brush wheel on the paperboard, and tighten the paper feeding belt. When you turn on the machine, you find that the rules are not good. You must also check the condition of the paper feed, and the pressure of the passing roller and the pressure roller. For thicker paper, the pressure of the roller and the brush roller should be heavier. And detect the time of paper and pull rules, as well as the timing of the transfer between the side gauge and the tooth, find the problem and deal with it in time, until the top and bottom and left and right rules are accurate and error-free.
