UV OPP SPOT INK MEDIUM (available in a few viscosity variants) is a UV curable high gloss transparent varnish for use on treated OPP (oriented polypropylene) laminated paper and board. Its viscosity is typically suited for manual or semi-automatic screen printing (line tests are recommended to confirm actual suitability). Typically, it is used in the printing industry as either a complete overprinting varnish or to create ‘spot effects’ on printed media to highlight selected features.
