Tinplate printing has higher color requirements
Tinplate cans are what we usually call tin cans, tin cans made of tinplate. Due to the special nature of tinplate, the printing process is different from the surface printing of ordinary items. Here are a few tips for tinplate printing.
Before tinplate cans are printed in color, tin box manufacturers need to print the printing area with white, because white is the primary color of all colors, and printing color after printing white can better highlight the color. Affected by the coverage ability of the ink, the monochrome machine is often required to print white again, and the whiteness can reach about 80%. Moreover, it is required that the white paint has a good binding force with the tinplate can and can withstand high temperature baking without discoloration.
Tinplate printing has relatively high color requirements. In addition to the high water resistance of the pigment, the coloring power and durability of the pigment are also relatively high. In addition to the characteristics of general offset inks, it should also With heat resistance, because the surface of the tinplate can is smooth and does not penetrate moisture, the ink is heat-fixed and needs to be baked at high temperature.
Since the surface of tinplate cans is impermeable to water, tin box manufacturers need to be equipped with a drying room in the printing process. The printed ink needs to be baked at high temperature to fully combine with the surface. The biggest difference between other offset printing is also a problem that we need to pay special attention to. Therefore, the tinplate printing line will be longer than other offset printing.
