Drip-off and Hybrid Coatings
Conventional inks are used for the process colors. A
special-effect print varnish is applied in the final printing unit
to the areas that are to have a matt appearance. Next, the coating
unit is used to apply a conventional full-area high-gloss coating
that drips off the areas previously given a matt coating. This
maintains the matt effect of these areas and gives the remaining
areas a gloss surface.
Hybrid or UV inks are used for the process colors. A further
printing unit is used to apply a UV special-effect print varnish to
the parts of the motif that are to have a matt appearance. Next,
the coating unit is used to apply a full-area UV high-gloss
coating. Because a UV high-gloss coating is used for hybrid
applications, a higher gloss level can be achieved than with a
drip-off application produced using a conventional, water-based
high-gloss coating. With hybrid applications, however, the
structure of the matt effect is stronger than with drip-off
applications. This surface with a less homogeneous appearance is
created because the UV coating absorbed is glossier than the
conventional coating which has been repelled.
