Problems needing attention in food packaging and printing

    First, the pressure of the drum should be adjusted properly in food packaging printing. If there is a slight carelessness in packaging printing, the rubber will be rolled; if the ink is too heavy and the solid bottom is too big, it is easy to stick the rubber or stick the ink roll. Therefore, the pressure of the drum should be reduced before printing, and the inner lining of the rubber should be reduced. In order to avoid sticking and rolling rubber, some additives or rutting adhesives should be added to the ink. At the same time, it is good to avoid double sheets, multiple sheets and paper skew, and ensure that the pressure is uniform and the rubber is not rolled.

    Second. Food packaging printing, like other printing products, requires accurate rules, otherwise it will affect its quality. In printing, we should adjust the height of front gauge and side gauge pressboard according to the thickness of paper. At the same time, we should adjust the pressure of pressboard wheel and brush wheel to tighten the loose tape. When starting the machine, it is found that the rules are not good, and it is necessary to check the paper moving situation in time, as well as the pressure of the paper passing wheel and the paper pressing wheel; for thicker paper, the pressure of the paper pressing wheel and the brush wheel should be heavier. The paper setting time and drawing time, as well as the hand-over time between side gauge and swing teeth were detected, and the problems were solved in time until the upper and lower and the left and right rules were accurate and without error.

    Third, ink has a direct impact on the quality of printing, 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, we must conform to the quality standard. To complete exquisite and beautiful products, we need to complete every step of printing carefully, so as to have considerable profits and quality.
