LithoGard™ LSO Gloss Quickset Packaging OPV

Above: overprint varnish being applied with a sheetfed litho printing unit. LithoGard conventional litho OPV's are applied using this method.

LithoGard LSO sheetfed conventional overprint varnish is Kerley's a premium, high-gloss, low-color overprint varnish for the highest quality applications that require a flexible, durable, freeze resistant finish. LithoGard LSO  is formulated to have a more plastic, pliable film than LithoGard SST. LithoGard LSO contains less PTFE & waxes than LithoGard GLOSS OPV, so dried films have good scuff resistance, yet are able to accept most hot stamping and self-adhesive labels. Testing for suitability first is always recommended, and we can provide samples. LithoGard LSO is formulated to be used in the press fountain, just like an ink. This means that LithoGard LSO varnish can also be used a “spot” varnish for selective application of varnish on the printed sheet.

LithoGard LSO also contains a long oil alkyd, enabling the film to continue to air-cure after impression to a very hard, yet flexible film capable of taking scoring and folds more readily than LithoGard GLOSS OPV. It also has less odor. LithoGard LSO, when properly applied and adequately air-cured, is capable of withstanding rub tests of several hundred strokes. LithoGard LSO contains cobalt drier, so it will form a skin when it is exposed to air. Contains micronized PTFE, which must be stirred from the bottom of any container after long periods of storage.

LithoGard LSO will pass Calif. AQMD maximum 300 g/L VOC content requirements, and contains 69% bio/renewable materials.
