What are the techniques for printing the bottom cover of chemical cans?

The use of Foshan iron cans is still relatively large, and the iron cans are also used in various industries. The range of use is still relatively wide, and the cans are also divided into many types. Chemical iron cans are one of them. So what are the techniques for printing the bottom of the chemical cans?

When the tin can manufacturer processes the tin cans, it needs to print first and then cut the iron, and then process it. Then the iron can is more important in printing, and the processing can not be completed if the printing is not completed. In printing, whether it is spot color or four-color printing, the color requirements, the adhesion of the ink, etc. are all strict requirements for the operation process. This article will give a brief explanation of the bottom cover printing, and share some tips on the process of printing iron!

All kinds of exquisite food tin cans, chemical tin cans, tea cans, toy tin cans, etc., which we have seen, are all the pattern colors that can be processed on the printed surface. The printing of tinplate and other materials is also different. First, the print area needs to be printed white before printing, because white is the base color of all colors, and white is also for better printing of other colors.

Chemical tin can printing has higher color requirements. In addition to the higher degree of water resistance of the colorant, it also requires high pigment coloring and durability. In addition to the characteristics of the offset ink itself, heat resistance and high temperature resistance are required. Because the outer layer of the chemical tin can does not penetrate moisture, the ink is heat-set and needs to be baked in the oven.

The outer surface of the tin can is not water-permeable, and the printing process is also equipped with a drying room. The printing ink is baked at a high temperature to enhance the adhesion of the ink. This is also a point that the tinplate iron printing process is different from other materials, and therefore the chemical iron is relatively It takes a long time to process tin cans.
