UV CTP
UV CTP is a process that replaces the traditional method of creating printing plates. In the traditional process, a film or digital file is used to expose the plate, which then goes through a series of chemical treatments to create the final printing plate. With UV CTP, however, the exposed plate is directly imaged using ultraviolet (UV) light.The UV CTP system typically consists of a computer, a plate setter, and the UV-sensitive plates. The digital file containing the print job is transferred to the plate setter, which uses UV light to expose the plate. This exposure process creates the image on the plate, which is then ready for printing.
