Oh Say Can UV?

While conventional offset inks dry or cure through their binding agents oxidizing and being absorbed into the printing stock, in UV printing, specially formulated inks are exposed to ultra-violet (UV) radiation, which causes them to harden instantly on top of the substrate. UV coating produces high levels of gloss or dull coating, vivid color and vibrant detail with superior rub resistance and no post-cure dryback—even on soft, uncoated sheets.
