principle ctp computer to plate is to planographic printing as the main object, the technology refers to all kinds of original text, images, electronic files, network files into the computer after processing, without other processes, the technology of directly exporting graphic information to printing plate, printing machine or paper by computer is the most directional printing technology in the 21st century. ctp plate can be divided into thermal plate, photosensitive plate and other imaging plate. the principle of thermal imaging is that the thermal component is coated on the aluminum plate in advance, and the light energy is converted into heat energy by the infrared absorption dye in the component of the scanned part through the infrared laser scanning at 830 nm, this causes the part to heat up, causes the potential proton acid to decompose and produce acid, and causes the resin part to cross-link under the catalysis of the acid, forming a relatively stable latent image, after processing or not developed liquid processing is usually called processing-free in the plate to obtain text or images. among them, infrared absorption dye in this process is the main role of light energy into heat energy.
