Photographs from the invention have a close relationship with printing. Photographic materials used in photolithography have been used for more than 150 years.
Silver salt photosensitive materials for printing are often called print films. In modern printing, whether it is offset printing, gravure printing, letterpress printing, or other forms of printing, most of its printing plates are inseparable from printed films.
Modern printing platemaking technology was based on hand-selected typesetting and photographic color separation before the 1970s; after the 1970s, with the wide application of electronic technology and laser technology, laser photocopying quickly replaced factory hand selection, electronic scores. Color replaces camera separation. This significantly speeds up the typesetting and typesetting speed, improves the image platemaking technology, and improves the printing quality.
At the end of the 20th century, the CTP technology as the core of the prepress process and full digitalization will enable the CTP technology printing industry to be applied. Further, Web publishing with Internet technology as its core, namely online publishing and electronic publishing, directly threatens the survival of printed materials. How long a printed film can survive is a major concern for film makers. In fact, there is no need to worry about the fact that the popularity of television has not affected the publication of newspapers and magazines. It has not only decreased but has also increased. Life is rich and colorful, and printed materials are still there. In the development of printing film, in the 1950s, the United States and DuPont Company first played a very important role in the use of polyester film as a support. The polyester film base is used as the substrate to make the printing film meet the requirements of color printing plate making; then the invention of the extrusion coating art technology realizes a huge change in the production process, so that the film production capacity and product quality have been significantly improved.
The international manufacturers of printing film are mainly Kodak Company of the United States, Agfa of Germany-Belgium, Juff Company, and Fuji Corporation of Japan. These three houses almost cut off the entire photosensitive material market. In the printing industry in China, their products have been used for many years, but their share is not much.
After 60 years of development, China's printing film has grown from nothing to small. Put it can be said that the major companies in the world have products we can produce. All kinds of printing films required for printing, China's photosensitive material production plants can be developed and put on the market in a timely manner. In the 1940s, Tianjin, Shanghai, Xiamen, Shantou and other places successively established workshop-style factories to produce a small amount of dry board and black and white photo paper. Before 1980, only Shantou AD photochemical factory imported polyester film base to produce the least printed film to meet the needs of printing and printing and dyeing industry. In the development of printed film in China, Second Glue plays a very important role.
The second film factory of China Lucky Film Group (formerly the second film factory of the Ministry of Chemical Industry) was established in 1969 and completed in 1973. The investment in the construction of the factory was 173 million yuan, which was a very important investment of the Ministry of Chemical Industry. The purpose of the establishment of the factory is mainly to produce film and military film, and the design scale is to produce 50 million meters (35mm wide) photosensitive material.
Due to the development and popularization of television, the movie industry has been greatly impacted. At the time, Dijiao was the only manufacturer in China that produced a photosensitive material with a polyester film base as a support. This unique advantage enabled Dijiao to start all-round research and development and printing all types of printed photosensitive materials from 1979.
In the past 20 years, after perseverance in scientific and technological development, technological transformation, and renovation and expansion, Dijiao has developed into a scientific research and production base for printed photographic materials in China. The Chinese Lekai Film Group, which is affiliated with China, is one of the 521 large-scale enterprises in the country.
In the early 1980s, Second Adhesive developed all kinds of printing films for photographic color separation, YZ series positive color printing platemaking films based on YZ-600, YQ-550 based YQ series full-color printing films, and Twelve varieties such as mask film and manual photographing were put on the market one after another.
In the mid-1980s, along with the development of the laser photocopying technology and electronic color separation technology in China, Second Glue developed the LP-6328 and LP-6328 II laser photo-taking films for helium-laser photocopying in a timely manner; Applicable to a variety of light source of the same type of electronic color separation. In recent years, with the development of the desktop publishing system that combines photocopying and color separation into one, with both text and images, Glue launched the RL-I laser image scanner. In 1998, it was successfully developed. In 1999, there was 1 million m2. Target market. Now the two plastic production of printed film should have: copy film: YZ-600II darkroom copy sheet, YZ-800 darkroom copy sheet, YZ-800 II darkroom copy sheet, GLR-II type bright sheet laser photo film: LP-6328II Laser Photo Film, LP-780 IR Laser Photo Film Laser Image Film: The properties and uses of RL-II Laser Image Scan Film are shown in the following table.

In 1999, the successful development of Dijia Laser Image Film (R L-II) and the country’s crackdown on smuggling increased the sales volume of Huaguang Printing Films by over 7 million m2. Huaguang's printing photographic materials have been widely used in the domestic printing industry and have gone global. In 1999, it exported more than 1 million m2.
With the development of computer technology and laser technology and the popularization and application of digital technology, the traditional concept of photography has also undergone fundamental changes. The development of these technologies has affected the development of the printing platemaking process technology, but the development prospects of printing photosensitive materials will still be colorful. In the next few years, China's printing film will develop in the following aspects. 1. Copying bright room laser photocopying, photography separation, and electronic separation continue to play a role, the imposition process is still inevitable, still need to copy; In addition, China generally adopts positive PS plate printing, so the printing of the printing film will continue to exist, but It is only natural that the copy will be developed into a bright room film. The quality of Huaguang GLR-II bright room copy is worse than that of foreign products. With the use of bright chambers, the working conditions for plate making can be significantly improved. 2. With the development of laser image scanning film computer imposition (electronic typesetting), today's desktop publishing system consisting mainly of microcomputers can not only arrange newspapers, books and magazines in various formats, but also can handle various fine color publications with the help of laser image scanners. In recent years, we will continue to develop vigorously. The plate-making machine entered the newspaper printing factory and the color printing factory, marking that CTP began to become practical in China. Only the Heidelberg QM DI46 plate-making machine had 10 units in China. Direct plate making technology is the development direction of the future printing plate making, and the development of self-making plates is imperative. Today, Dijiao has a complete production line from polyester film tenter to film production and finishing. It has imported key equipment from Japan, with a width of 2.6 meters, and an annual output of 5,000 tons polyester film tenter production line; from the United States, Japan and other countries have introduced key equipment with a speed of 80 meters per minute, annually producing film coating lines with a production capacity of 100 million m2 for each type of printing film, and four PS production lines with an annual production capacity of 15 million m2. In the 22 years since the start of production of Dijiao, it has produced a total of more than 100 million m2 of photosensitive materials, and has achieved a total industrial output value of more than 3 billion yuan, and turned over more than 200 million yuan in profits and taxes. The strength possessed by Dijiao has laid a solid foundation for the research and development of direct plate materials.
After years of efforts, silver-salt composite direct plates for He-Ne laser and argon-ion laser have been successfully developed. Silver salt diffusion type plates have entered the trial stage.
The heat-sensitive plate-making plate, in cooperation with Beijing Normal University and East China University of Science and Technology, has been experimentally coated with a trial version that can be printed on the machine. At the beginning of this year, in Liaomei and Heidelberg, Beijing, printed plates were printed on the QM DI46 plate making machine in Heidelberg. The plates were printed with good ink receptivity, the printed images were clear, the dots were clearly better than the PS plates, and 2% outlets Qi Huaguang. The sensitivity of the thermal negative CTP plate is close to that of the KPG negative plate Thermal830. With the application of various high and new technologies in the field of printing workpieces, the requirements for the variety and quality of printed films will become higher and higher. With China's accession to the WTO, foreign large companies will bring new products to the domestic printing and printing photographic materials industry. Impact. As a secondary rubber factory engaged in the research and production of printed photosensitive materials, we must redouble our efforts to ensure sustainable development in the highly competitive market. 1990-1999 Huaguang Printing Film Sales List Year 1990 1991 1992 1993 1994 1998 Sales (10000m2) 148 202 325 426 540 532 728
