Effective process to remedy the problem of Corrugate Boxes discoloration

In production, due to improper quality control, the surface of the formed corrugated box has problems such as discoloration, and even the loss of old customers! Based on this situation, we can actually formulate an effective process remedy:

The specific method is: if the carton is blue, according to the characteristics of the blue layout of 10cm × 50cm, use a brush with a width of 11cm and soft characteristics, dip in the wear-resistant water-based varnish, and evenly go back and forth along the blue layout. Brush twice, so that after the printing color layout is covered with a layer of water-based varnish, the effect of protecting the printing ink layer is better.

In the process of rework, it should be noted that the Corrugate Boxes that has been painted with varnish should be placed upright to dry to avoid adhesion. The wear resistance of the ink layer on the printing plate is greatly improved, and the disadvantage of easy color fading no longer occurs, and economic losses are better avoided.
