In UV ink printing, the most common problem that plagues operators is color bleeding. This issue is typically caused by an inappropriate printing sequence, printing pressure that has not been adjusted to the optimal level, or excessive flow of the UV ink. How can color bleeding in UV ink be resolved? To address this issue, we recommend focusing on the following two areas.
1. Arrange the printing color sequence appropriately
Color bleeding is most likely to occur when there are significant differences in the ink coverage of the various colors in a print design. In such cases, the color sequence should be adjusted based on the actual ink coverage of each color. It is recommended to print the colors with lower ink coverage first and the colors with higher ink coverage last. This approach not only effectively prevents color bleeding but also maximizes ink coverage, resulting in richer, more vibrant colors.

2. Adjust the printing pressure appropriately
Adjusting printing pressure is also critical to resolving color bleeding issues during UV ink printing. For example, the pressure between the blanket cylinder and the plate cylinder must be adjusted to within the standard range; it is best to use UV-specific blankets; and key color units should be equipped with independent UV curing units.
