Overprint Varnishes (OPVs)
Formulated into water-based OPVs, fine-particle wax emulsions increase block, rub, scuff and/or water resistance—without adversely affecting gloss. To meet the varying needs of different printing processes and ink systems, numerous Michelman products are used in OPVs. Several are FDA-approved for food contact.
