Cardboard is a direct substrate, and its condition is closely related to printing. If the surface of the face paper is rough, has a high moisture content, is dusty, and has poor ink absorption, automatic folding gluing machine its printing effect is not good. If the cardboard structure is not flat, such as missing materials, collapsing edges, partial degumming, surface blistering, folding, warping, etc., it will seriously affect the printing effect. If the moisture content of cardboard is too high and the cardboard does not have stiffness, it will also make printing difficult.

In addition, printing plates are the foundation for good cardboard printing, and without plates, printing cannot proceed. Modern cardboard printing uses a flexible photosensitive resin layout, which has the advantages of accurate reproduction of the original manuscript, good printing effect, and high printing resistance. The printing scale should be consistent with the manufacturing scale of the cardboard box (it is larger than the inner scale of the cardboard box and smaller than the outer scale). When calculating the scale, full consideration should be given to the indentation on the prepress cardboard. Before making the plate, it is necessary to carefully review the original manuscript, and for areas that do not meet the plate making requirements, it is recommended to refer to and improve them. After the automatic carton folder gluer machine printing process is completed, it is necessary to carefully check the exposure and washing conditions. It is necessary to manufacture from scratch if it does not meet the specifications. After each printing completion, the printing plate should be carefully cleaned and no residual ink is allowed, otherwise it will have a serious impact on the printing function of the sponsor; It may result in serious shortcomings such as unclear handwriting and burrs. In response, our company has developed a comprehensive printing plate management system, which ensures multiple checks before production, careful inspection after the printing plate arrives, careful cleaning after printing, and proper storage to ensure the quality of the printing plate.
