What happens when uv ink is over cured?There is a theory that when the ink
surface is exposed to too much uv light, it will become harder and harder.
When people print an ink on the hardened ink film and dry it for the second time,
the adhesion between the upper ink and the lower ink will become poor.
What happens when uv ink is over cured?Another theory is that excessive curing
will cause photo oxidation of the ink surface. Photooxidation will destroy the
chemical bonds on the surface of the ink film. If the molecular bonds on the surface
of the ink film are degraded or damaged, the adhesion between it and another ink
layer will be reduced. The over cured ink film is not only less flexible, but also prone
to surface embrittlement. The over cured ink film is not only less flexible,
but also prone to surface embrittlement.
What happens when uv ink is over cured?The uv ink on the surface of the printed
matter can not be applied, and the printed matter will become blurred. Cause: uv varnish
viscosity is small, coating is too thin. Ink contains too much ink mixing oil or dry oil.
The ink surface has crystallized. There are many anti stick materials on the ink surface.
Gluing screen roller is too thin. Solution: Corresponding measures must be taken to
create conditions for the printing of products requiring uv glazing. The uv ink should
be applied thicker, and if necessary, the problem can be solved by
priming oil or replacing special ink.
