UV Coating
From Wikipedia, the free encyclopedia
UV coating is the name given to various processes and coverings that utilize or protect against ultraviolet radiation.
[edit] Ultra-violet coating of paper
Ultra-violet coating is a glossy coating applied over ink printed on paper and dried by exposure to UV radiation. UV coating is applied by silkscreen.
UV coating/varnish is glossier than all of the other coatings. 80 text and heavier weights of paper can be UV coated, however, cover weights are preferred. UV can be used on smooth, uncoated papers.
UV can be applied on spot locations of the paper or by flooding the page. This coating application can deepen the color of the printed area. Drying is virtually instantaneous when exposed to the correct level of UV light so projects can move quickly into the bindery. Like the other coatings, consult the bindery for projects requiring gluing.
A printed page with UV Coating applied has a very shiny and also slightly sticky feeling.
[edit] Ultra-violet coating of glass and plastic
Glass and plastic can be coated to diminish the amount of ultraviolet radiation that passes through. Common uses of such coating include eyeglasses and automotive windows. Photographic filters remove ultraviolet to prevent exposure of the film or sensor by invisible light.
