CTP plate (Computer to plate): From the computer directly to the printing plate, that is, “offline direct plate making”. It was first developed from photo-to-plate making, all using computer-controlled laser scanning and imaging, and then printing plates through processes such as developing and fixing. This technology eliminates the intermediate medium of film and enables text and images to be directly converted into numbers, reducing the quality loss and material consumption in the intermediate process. This is usually the CTP Plate.
Plate classification
There are four main types of CTP plates according to the principle of plate making and imaging: photosensitive system CTP plates, thermal system CTP plates, violet laser system CTP plates, and other system CTP plates. Among them, CTP plates of the photosensitive system include silver salt diffusion plate, high-sensitivity resin plate, and silver salt/PS plate composite plate; thermal system CTP plate includes thermal crosslinking plate, thermal ablation plate Thermal transfer plate, etc.
