UV Varnish - What is UV varnish?
A type of varnish coating that is cured by exposure to UV light. UV varnishes usually have some solid content and can be produced as 100% solids that are applied as a thin film; they dry almost instantly when exposed to UV light.
In labelling, UV varnishes are applied to face materials to enhance the appearance of the surface by adding a gloss finish (although flatting agents can be added to produce semi-gloss or matt finishes) and to add a protective coating. It should be noted that while these varnishes are cured by UV light, they do not offer protection against the harmful effects of exposure to UV light. They can be applied during the manufacturing process or after printing and are either over coated (cover the entire surface) or spot coated (cover sections of the surface).Go Back to Glossary
