In 2002, 30 mW purple laser diode appeared, and applied in the CTP plate system, at this time has been able to quickly plate, the corresponding violet photopolymer plate variety has diversified, not only silver salt CTP plate, high sensitivity 410nm photosensitized version, and moderate sensitivity photosensitized CTP plate also began to adapt to the purple laser CTP plate system.International plate manufacturers began to market their own purple laser CTP plate.
After 2003, with the emergence of 60 mW, 100 mW and even more powerful lasers, there will be more plates that can meet the requirements of purple laser plate making system.In addition to photosensitive plate, various violet photopolymer plate and performance improvement, the market for users to choose violet photopolymer plate is very rich, to relieve the user's worries.


 
Domestic and foreign plate manufacturers and brand violet ctp plate can be divided into silver salt plate and light polymerization version of two.Silver halide plate contains a silver halide layer, which is diffused to form a metallic silver image area on the plate. This layer is light sensitive and has fast exposure. 5 mW laser is enough, and the printing process is 350,000 yuan.Photopolymerized version USES free radical to induce polymerization to produce alkali insoluble polymer, which can be developed with water based drugs, and the waste solution does not contain silver or other potential harmful substances.Its printing process is 200 thousand ~ 350 thousand, after baking up to 1 million.
