CTP plate is the application of Computer to Plate technology to directly send graphic and textual information to the plate making machine through a computer, and directly image it on the CTP plate. After development and processing, it forms a printable plate

According to imaging principles, CTP plates are currently divided into three categories: photosensitive CTP plates, thermosensitive CTP plates, and inkjet CTP plates. The photosensitive CTP plate is divided into silver salt diffusion type and photopolymerization type CTP plate. Thermal CTP plates are divided into hot melt type and heat exchange type CTP plates. Inkjet CTP plates are divided into PS plates and bare plate types. Compared with PS plates, CTP plates do not require film exposure during the plate making process, so there are fewer information transmission links and less transmission loss, which provides better assurance for printing high-precision products. During the entire plate making process, due to the reduction of links, the printing cost will also decrease, and the printing cycle can be shortened to a certain extent. The drawback is that due to the discontinuation of film output, quality inspection can only be checked against the printed sample after printing, making it relatively more difficult. In addition, if damage is found to the CTP plate during printing, and the printing factory does not have a CTP plate making machine, it will also be time-consuming and laborious to remake the CTP plate.
