Overprint Varnish Performance Program

RIT’s HP Indigo Overprint Varnish Performance Program enables manufacturers, suppliers and HP Indigo digital press owners to have both waterbase and UV coatings evaluated with HP Indigo digital certified media. The OPV Performance procedure incorporates several tests in accordance with the stated protective uses for the coatings.

As an initial screen test, the OPV will be applied to a certified printed media. The OPV will be evaluated for adhesion to the HP Indigo ink and visible orange peeling or mottling. After passing the initial screen test, the coating will be applied to specific test targets for evaluation of chemical and physical properties.

Once completed, a comprehensive report is then generated for each OPV/substrate combination and given to the supplier.

Evaluation Description

The OPV procedure evaluates coatings through the following tests:

  • Peeling Tests
  • Full Baseline Test
    • Mechanical Wear
    • Optical Tests
  • Heat Resistance and Aging Tests (Optional)
  • UV Light Resistance Performance (Optional)

Evaluation Fee

  • Full Baseline Test - $725 on coating on one substrate
  • Heat Resistance and Aging - $115 one coating on one substrate
