Domestic and foreign printing photosensitive materials (on)

First, PS version - the most commonly used photosensitive materials for printing
The PS version is a foreign language introduced from English. It refers to a presensitized plate, and English is Presensitized Plate. PS version is widely used in offset printing at home and abroad. At present, global production has exceeded 400 million square meters/year, and China's output is about 70 million square meters/year.
China's printing industry mainly uses the positive PS plate. During the plate making process, the image formed by it is the same as the image using the film manuscript; individual users use the negative PS plate. During the plate making process, the image formed by it uses the film manuscript. The image is the opposite. In foreign countries, countries such as the United States, Great Britain and the United States use the negative PS version, while other countries use the positive PS version. The difference in the main performance of various PS versions is also reflected in the speed, resistance, force, resolution, exposure and development latitude, vacuum time, vacuum adhesion, print contrast and so on. With the acceleration of people's life and production rhythm, the high-sensitivity PS edition is more and more popular with users. The research and development of the high-sensitivity PS edition is increasingly valued by PS makers.
China's printing industry mainly uses conventional-thickness PS plates, small offset printing systems mainly use small offset printing plates, and small offset printing plates use a plate thickness of 0.15 mm.
Over 20 years of reform and opening up, the rapid development of China's printing industry has promoted the rapid development of the PS industry. PS producers both at home and abroad have increased investment in PS production. In the near future, China will become the PS version. Big country of production.
As China's PS version has the advantage of price, the export volume is getting bigger and bigger. In the near future, China will also become a large exporter of the PS version.
Second, CTP version - the most promising printing photographic materials
We entered the computer age, and the increasing development of digital printing has promoted the development of digital printing plates. We call the CTP plate digital printing plates. The CTP version is also a foreign language introduced from English. It refers to a computer-to-plate format for computer-to-plate calculations. It is a new type of special PS version. It can directly receive computer-processed images, and ordinary PS version reception. Computer-processed images also require film as an intermediary medium.
The CTP plate is a research and development hot spot for printing photographic materials. With the increasingly mature research and development of the CTP plate, the applications in the United States and Europe have become more and more extensive. China has also developed rapidly and is the fastest in Guangdong. China's CTP version of research and development has also made great progress, Lekai Group Second Offset Factory, Beijing Normal University, Institute of Physics and Chemistry, Chinese Academy of Sciences and other units in China's CTP version of the research and development of a leading position.
At present, the most widely used CTP version is the thermal CTP plate, which accounts for half of the CTP plate market. The most mature thermal CTP version is the negative thermal CTP plate, negative thermal CTP plate has a high resistance to print force, high resolution, but the need for warm-up is the shortage of the plate. Positive thermal CTP plate does not need to be warmed up, but the resistance and resolution must be further improved. The flush-free thermal CTP plate is available in the mechanism version, but the printing machine with the device version in the mechanism is expensive, and most printers can only look at Xinghan. Printing companies using thermal CTP plates may experience high levels of confusion in the operating costs of thermal CTP platesetters. The thermal CTP plate is more suitable for large printing manufacturers. Lok Kai Group's second offset printing plant has mass-produced negative thermal CTP plate for customers at home and abroad, and has already produced a positive thermal CTP plate for trial by users.
CTP version of the rising star is the violet laser CTP version, violet laser CTP version of the biggest advantage is to match the violet laser CTP platesetter violet laser scan head low cost, reduce the cost of CTP plate making, for medium-sized printing manufacturers have great The temptation, purple laser CTP version will continue to expand in the market share. At present, the purple laser CTP plate has been put on the market with a silver salt type violet laser CTP plate and a photopolymer polymer type violet laser CTP plate. Purple laser CTP version is more suitable for medium-sized printing manufacturers. Lokkai Group's second film factory has already produced a silver salt type violet laser CTP plate for trial by users. (To be continued)
