What Are The Common Problems When Printing Cosmetic Iron Boxes?

In recent years, with the continuous improvement of printing equipment and technology, the printing process of cosmetic iron boxes has become increasingly advanced. Even so, different problems may still arise in the actual printing process of iron cans and boxes.
1、 Inaccurate printing sleeve position
The printing accuracy of iron materials is closely related to the aesthetic appearance of iron cans. Even if there is a slight misalignment in iron material printing, it can have a significant impact on the overall printing effect of iron cans. In severe cases, it may even be scrapped, and there are many reasons for misalignment in printing. The precision of equipment, layout errors, and whether workers operate in a standardized manner can all affect the misalignment in printing.
2、 Adhesion between iron material and drum
During the printing process, if the iron material adheres to the drum, it can easily cause the iron material to shift, resulting in problems such as ghosting and misalignment in the iron material printing.
3、 Different shades of printing colors
There are many reasons for the varying shades of tinplate printing colors, such as the oxidation and discoloration of ink, uneven ink layer after printing, varying pressure levels on the machine, or poor cleaning of the ink rollers of the printing machine, which can cause problems.
