UViGard™ DULL UV-cure Overprint Varnish OPV

Above: overprint varnish being applied with a sheetfed litho printing unit. UViGard UV-cured OPV's are applied using this method.

UViGard DULL overprint varnish is a UV-curable matte-finish, on-press overprint varnish. Tack is reduced so that it may be run in the last unit wet-on-wet ink with minimal back-trap. UViGard cures to a clear, water-white finish due to Kerley's exclusive us of Kerley's non-yellowing Exocure WPI photoinitiator package. Cure is instant and hard enough to be burnish-resistant.

UViGard DULL OPV cures to a very hard, flexible film and can be used for a variety of applications such as brochures, catalogs and folding cartons. Adding 1-3% percent of Kerley's Exocure WPI liquid photoinitator enables UViGard to be used as a high speed web offset overprint varnish as well.

 

UViGard DULL OPV requires the use of an absorbent substrate like paper or board stocks, a primer coat, or a surface treatment to increase surface energy on non-absorbent substrates (ie: metal, plastic) in order to ensure excellent adhesion.

UViGard DULL OPV is produced ITX-free.
