| CTP is a long history of development, and as early as 1978 the Americans proposed the idea; to 1980, began to study the direct plate-making technology, but the plate regardless of technology or quality are not mature at an early stage; until the 20th century, 90 years have a greater development in the Drupa95 exhibition, a total of 23 manufacturers on display 43 kinds of direct plate-making equipment. Drupa95 exhibition, the to-plate technology has made significant progress in 1996, the printing industry in the top 100 U.S. large enterprises, 55% used a plate system; 1997, the U.S. has 65% of large-scale printing using the CTP technology.
In Drupa2000 exhibition, CTP technology has become the focus of attention in the printing industry, there are more than 90 companies exhibited nearly a hundred plate CTP systems and materials, indicating the CTP plate technology as the light source and photo-typesetting technology mature. CTP market is expanding, making the imagesetter sales are decreasing trend, the current production of many international companies into the CTP imagesetter system development. In Europe and other developed countries have launched a direct use of CTP printing plate and boom, the current market share is that North America accounted for 45%, Europe 38%, 17% elsewhere. Application as follows: 60% off business, the press 11%, 9% super-large format, eight opening of 4%, 16% quarto.
At present, China has imported several sets of computer to plate systems, all rely on the use of plate imports, higher prices. With the localization process and the demand increases, prices will be gradually reduced. Epmedia2000 exhibition, China's computer to plate system will have greater development. According to the survey at the exhibition, expected next year, will import 20 to 25 sets of CTP system. China in the next five years, CTP and plate system will have greater development, if BIEP94 exhibition to promote desktop publishing (DTP) development, Epmedia2000, and to promote the development of the CTP. Although our CTP technology is still in its infancy, but with the CTP technology matures, the required plate prices gradually decline, with China's imminent accession to the WTO, I believe CTP technology in the near future will be the same as the DTP technology rapidly. Because in the long run, CTP has a great advantage, better plate quality, higher production rate, saving space, manpower, saving the middle of the process materials and equipment, thereby reducing costs.
Outlook 2000 to 2010, China's printing industry is the basic direction of technology development: "pre-press digital, networked, multi-color printing, more efficient, diverse after printing, automated, high-quality equipment and serialization." This indicates that the next 10 years China will have great development of the CTP market. From the current situation of China, has made the advent of CTP plate system, which also indicates that China's computer to plate has been close. In addition to China should vigorously research and introduced domestic CTP equipment, of course, should also strengthen the plate in the research and production.
PS version of the current domestic production companies are China Academy of Printing Technology, China Lucky Film Group Second Film Factory, Jiangsu Taixing East Industrial Company, Taixing Yongsheng Printing Equipment Co., Ltd., Zhengzhou nations printing plate Limited. China Academy of Printing Technology is being jointly developed with Japan's Fuji, production can be used for the traditional PS version of the CTP, said in 2001 to market, which undoubtedly will effectively promote the use of computer to plate process. China Lucky Film Group Second Film Factory is also being developed TN-Negative (negative, need to warm up) and TP-type Negative (positive, no warm-up) of the thermal plate, SA-type, SY-type, SR-type silver halide diffusion transfer CTP version, SPR-based, SPIR polyester base silver salt diffusion transfer version of the CTP, if these plates on the market, will make lower cost of CTP plates.
With desktop publishing (DTP) system and the rapid development and the digital, networked widely used in printing, CTP system and the technology has become one of China's printing industry development, we welcome with great enthusiasm CTP era .
