Solution to the 9 major problems of flexo UV glazing (4)


Glazing effect is unstable
In the flexographic printing process, in order to stabilize the viscosity of the water-based ink, it is necessary to add a certain amine substance to the ink. Although the viscosity of the ink can be effectively maintained, some amine substances may have a negative influence on the curing effect of the UV varnish. Solution: If the varnish and ink do not match, replace the varnish or change the varnish formulation.
