The speed, durability, and high resolution of the prints made over a wide surface have transformed the printing industry all over the world with the introduction of wide-format UV printing. Unlike solvent or latex printing, the UV-curable wide-format printing employs the use of ultraviolet (UV) light to harden the ink immediately on different media, causing the immediate drying process, vivid colors, and outstanding surface durability.
