Corrugated Box Printing Common Problems

5. Inconsistent printing colors

Analysis of reasons: Inconsistent printing color means that the board is not uniformly printed along the longitudinal or transverse direction of the machine after printing. The reason for this problem is mainly due to the different colors at the two ends of the horizontal printing. One side is lighter and the other side is darker. There is an unfavorable circulation of the ink system, insufficient ink flow, and uneven transfer of the ink transfer roller.

Solution: The horizontal color is uneven due to the different gaps between the rubber roller and the anilox roller, the anilox roller, and the plate roller. Therefore, to adjust the gap between these three rollers, both ends must be kept parallel. Because the printing slotting machine is centered, such as the production of narrower cardboard, the roller and the anilox roller will wear faster, and the two ends wear less, the result after printing is not the same, if the two ends of the color Obvious inconsistency, you need to repair or replace a roller. The non-uniform color in the longitudinal direction is caused by the insufficient ink flow and insufficient ink supply. Therefore, it is necessary to add a small amount of ink to the machine to run idle to allow the ink volume to be fully recycled before production. This will reduce the occurrence of problems in this area.
