Screen printing failures and countermeasures - back sticking

Thirteen, the back of the dirty

Dirty on the back refers to the phenomenon that the ink on the lower print sticks to the back of the upper print when the prints are stacked. If this phenomenon is not controlled, it will cause the page to stick and affect the printing of the other side of the double-sided print. The main reason for the back stickiness is poor ink drying.

The solution to the problem of sticking on the back side is to adjust the viscosity of the ink, use a quick-drying ink, add a driers to the ink, or spray powder on the surface of the semifinished product, or a liner.
