Michelman has expanded the range of DigiGuard UV overprint varnishes allowing HP Indigo press owners to extend the application range by meeting the industry's durability and resistance standards for high-performance labels. New UV overprint varnishes (OPVs) permit HP Indigo digitally-printed labels to endure harsh environments, including extreme heat, chemicals, water, or friction during packing and transport. These technologies allow press owners to increase the addressable market size and produce more with their HP Indigo digital label presses in applications such as packaging for personal care and cosmetics, household cleaners, automotive oils and fluids, wine and beer bottles, and industrial and electronic equipment.
