Overprint Varnishes For Gravure Printing

Overprint varnishes, one of the typical coatings, are utilized to protect the ink layer as well as to add a special finish to its appearance while enabling properties enhancement that is essential to the whole laminated film structure.

In gravure printing, OPVs equipped with the features like heat resistance, slip resistance, scratch resistance, textured effects, etc are several common types.

Let’s take quick glance through several notable matters when it comes to Gravure Overprint Varnishes (OPV) and how Toyo Ink Vietnam (TIV) responds to those with its latest product lineup.

Scratches, in any case, are simply not desired, and our OPVs are developed with priority to help avoid such unwanted matters.

resistance

Adhesion between two surfaces when pressure is applied, better known as “blocking” is no doubt unfavorable. Our OPVs purely offer a way out for that.
