Poor strength cardboard, how to get rid of powder, blistering and other ills in printing

[Chinese Packaging Network News] The surface of the poor strength of the white cardboard, the printing process prone to paper powder, blistering or delamination defects, not only affect the printing efficiency, but also affect the quality of printing, how should it be handled?

In this regard, the solution is as follows:

One is to properly adjust the viscosity of the ink, and use an adhesive to adjust the viscosity of the ink;

The second is to adjust the appropriate printing pressure to print with the lightest printing pressure possible, so as to reduce the damage to the paper surface strength caused by the pressure.

The third is to properly reduce the speed of the machine for printing, to reduce the printing ink peel force on the paper surface force;

The fourth is to rationally arrange the printing color sequence, printing should be used as far as possible: the first printing small layout after printing large layout; first printing low viscosity ink after printing ink with high viscosity;

The fifth is the air imprinting on the printed sheets, which can make use of the extra color groups, first stamping the printed sheets or "overwatering" them;

The sixth is to adjust the printing of whiteboard with poor printing surface strength. For example, the viscosity of liquid ink with flexo printing is lower than the viscosity of offset printing and embossing ink, and can be adjusted with flexible printing process, or adjusted for products with small printing area. Through this process arrangement, the cardboard is better protected from powdering, blistering or delamination.
