What is thermal technology? Thermal CTP technology uses a red laser generator with a wavelength of 830nm or 1064nm to expose the surface of the printing plate, and the coating of the printing plate undergoes a thermal chemical reaction, or through thermal ablation or thermal phase change to make the text and non-graphic text Partly produce different chemical properties to realize the reproduction of image information on the printing plate. More than 60% of CTP equipment worldwide uses thermal technology. At present, the main thermal CTP equipment suppliers include Kodak, Agfa, Screen, etc., and domestic brands such as Corey, Leopard Chi, Poly, China-India Zhou Jin, etc. also provide thermal CTP plate-making equipment, and technology It tends to mature and the quality tends to be stable. Thermal plate At present, most of the plates on the market with thermal CTP equipment are thermally sensitive chemical reaction plates, that is, the coating of the plate undergoes a thermal reaction (thermal cross-linking reaction or thermal decomposition) under the irradiation of red laser The exposed parts and unexposed parts have different dissolution properties in a specific solution, and then the undesired parts are dissolved and removed by the developing solution, and the required graphic information is retained on the plate surface to realize the plate making of the printing plate material. The heat-resistant CTP plate has a very high print durability. The general heat-sensitive plate can easily achieve a print durability of more than 100,000 prints. If it is baked, it can achieve a high print resistance of more than 1 million prints. In terms of plate materials, the world's three largest plate material suppliers-Kodak, Agfa and Fujifilm all have a series of thermal plate materials, while the major domestic suppliers, including Lucky Second Glue, Chengdu Xintu, etc. There is also a mature product supply market. A large number of small and medium-sized printing plate manufacturers in China are involved in the CTP market, and the breakthroughs are all thermal CTP plates. Now, the price of domestic thermal CTP plates is getting closer and closer to the price of traditional PS plates. The prices of equipment and plates often criticized by the industry, at least in the field of thermal, are no longer the bottleneck restricting the application of technology. . Thermal CTP has also become the most commonly used CTP plate-making technology in China. Advantages of thermal technology 1. High quality: the digital printing plate imaging technology can get clearer and sharper dots than the analog printing plate imaging technology (CTF). The shape and size of the dots are tighter and finer, which can produce 1% to 99% dots at 300lpi screen lines The dot diameter can be as small as a few microns, the edge is very straight, and the surface is very flat, which can optimize the ink delivery. 2. High printing resistance: The thermal plate is not easy to wear and can be used for a long time. After baking, the printing resistance can reach 1 million to 2 million prints. 3. Can be operated in the bright room. Disadvantages of thermal technology 1. The prices of thermal equipment and plates are relatively high, higher than those of visible light imaging plates, and more expensive than traditional offset PS plates 2. Exposure to thermal plates requires more energy than exposure to visible plates.
