Purple Laser CTP Plate Origin The original purple laser was only 5mW, and it could only be exposed to the silver salt CTP version. Generally, the sensitivity of the photosensitive version could not meet the requirements. Therefore, there is only the silver salt diffusion transfer version on the market. In 2001, when the plate-making machine used a 15mW violet laser, it could already expose high-sensitivity photopolymerized plates. However, there are fewer varieties of such plates and fewer manufacturers. In 2002, the 30 mW purple laser diode appeared and was applied to the CTP plate-making system. At this time, plate-making could be quickly performed. The corresponding varieties of purple laser CTP plate materials appeared diversified. And the photosensitive CTP plate of medium sensitivity has also begun to adapt to the purple laser CTP plate-making system. International plate material manufacturers have begun to launch their own purple laser CTP plate materials to the market. After 2003, with the advent of 60 mW, 100 mW and even more powerful lasers, more plates can be used to satisfy the purple laser plate-making system. Coupled with the sensitivity of the photosensitive plate, various violet laser CTP plates and improved performance, the purple laser CTP plates available for users on the market are very rich, which relieves users' worries. The domestic and foreign plate material manufacturers and brand purple laser plate materials can be divided into silver salt plate and photopolymerized plate. The silver salt plate contains a silver halide layer, which is diffused to form a metallic silver image area on the plate surface. This layer is sensitive to light and has a fast exposure. A 5 mW laser is enough. The photopolymerization version uses free radicals to initiate polymerization to produce alkali-insoluble polymers, which can be developed with an aqueous kit. The waste liquid does not contain silver or other potentially harmful substances. Its printing process is 200,000 to 350,000, and it can reach 1 million after baking. The second film factory of Lucky Group, Zhongkeyin, Shanghai Institute of Printing Technology, etc. have all invested in scientific research and development of purple laser CTP plate materials, and have achieved results. The laser CTP plate material has been domestically produced, paving the way for the newspaper industry to adopt the purple laser CTP technology for cheap plate materials. Purple Laser CTP Plate Classification The violet laser system has an open plate material supply. Almost all mainstream CTP manufacturers produce it, including several domestic companies. The supply of plate materials is very guaranteed. And it is foreseeable that the price of plates will continue to decline. Violet laser CTP plate material is visible light series, it is divided into silver salt plate and photopolymerized plate. The silver salt plate contains a silver halide layer, which is diffused to form a metallic silver image area on the plate surface. This layer is sensitive to light and fast exposure, and only 5mW laser is enough. Its durability is about 350,000 prints, without baking. However, the developer contains harmful ingredients and needs to be treated in an environmentally friendly manner; the photopolymerized version only contains photopolymers, and the waste liquid contains no harmful substances, and can reach 1 million prints after baking. The original purple laser was only 5mW, and it could only be exposed to the silver salt CTP version. The sensitivity of the general photosensitive version could not meet the requirements. Therefore, there is only a silver salt diffusion transfer version on the market. When the 15mW violet laser was used in the plate-making machine in 2001, it was able to expose high-sensitivity photopolymerized plates. In 2002, the 30mW purple laser diode appeared and was applied to the CTP plate-making system. At this time, the requirements of rapid plate-making have been met. The corresponding varieties of purple laser CTP plate materials have also diversified. Not only the silver salt CTP plate, high sensitivity 410nm photosensitive Version, and the photosensitive CTP plate of medium sensitivity has also begun to adapt to the purple laser CTP plate-making system. International plate material manufacturers have begun to launch their own purple laser CTP plate materials. After 2003. With the advent of 60mW, 100mW and even higher power lasers, more plates can be used to satisfy the violet laser plate-making system. The light source energy of next-generation products of purple laser light source will reach 200mW or even higher, which provides a broad prospect for further improving the production efficiency of purple laser CTP system. The emergence of processing-free plate materials further strengthened the competitiveness of purple laser CTP. We know that when the power of the laser head reaches more than 150mW, it can achieve no-rinsing like thermal technology. This is another big impact on the thermal CTP, because in the past only thermal CTP can be rinse-free. Now the market has already begun to supply CTP plate without processing violet laser. Violet laser-free chemical processing plate is an environmentally friendly product that helps us achieve green printing. The amount of printing plate glue is very low and the waste liquid generated is very little. The waste liquid generated by it is less than 1/20 of the traditional film platemaking, and 1/10 of the traditional direct platemaking plate material, and saves the cost of the developing solution.
