How to solve the problem of insufficient adhesion of uv ink?When printing on some non
absorbable printing materials such as gold and silver paperboard, due to the short curing
time of uv ink, the problem of low adhesion of uv ink to the substrate sometimes occurs.
Insufficient adhesion of uv ink will have a great impact on the printing quality and
subsequent processing of products.
How to solve the problem of insufficient adhesion of uv ink?To solve the problem of insufficient
adhesion of uv ink, the usual measure is to conduct corona treatment on the substrate material,
so as to change its polarity and increase the bonding ability between uv ink and its surface,
thereby improving the adhesion of uv ink. In addition, the curing effect of uv ink directly affects its
adhesion. If it is verified that the problem of insufficient adhesion of uv ink is not caused by
the curing quality of printing materials and uv ink, you can consider whether it is the quality of
uv ink itself. In this regard, printing enterprises need to strengthen communication with uv ink suppliers
and try to add an appropriate amount of adhesion promoter to improve.
