Adhesive suitability and printability
A good varnish coating forms a 100% solid film on the surface of the ink layer. The coating is like a plastic film with a smooth surface. This is very disadvantageous for post-processing such as gluing, and the adhesive and ink cannot adhere at all. Solution: The varnish coating must have good applicability and printability. Test before use. Contact the varnish supplier to find a solution.
