The fourth generation laser imagesetter has been developed abroad, while China is still in the lead printing era. China government intends to develop its own second and third generation laser imagesetters. Wang Xuan boldly chose a technological leap and directly developed the fourth generation laser phototypesetting system, which has no products in the west. In view of the characteristics and difficulties of Chinese characters, he invented the high-magnification information compression technology and high-speed restoration method of high-resolution glyphs, took the lead in designing the corresponding special chip, and used the "parameter description method" to describe the characteristics of strokes for the first time in the world, and obtained invention patents in Europe and China. These achievements initiated a new era of Chinese character printing, triggered a technological revolution of "farewell to lead and fire, stepping into light and electricity" in China newspaper industry and printing and publishing industry, and completely changed the movable type printing technology used in China for hundreds of years. The domestic laser phototypesetting system has enabled China's traditional publishing and printing industry to complete the technological transformation from movable type typesetting to laser phototypesetting in just a few years, which took decades in the West. It is recognized as the second revolution of printing technology in China after Bi Sheng invented movable type printing. 1. Wang Xuan, introduces a new type of computer, computer dynamics, 1978, 1 1.

Wang Xuan, Four Key Technologies for Promoting the Development of Newspaper Industry and Printing Industry, High-tech Development Report of China Academy of Sciences, Science Press, 2000. 1979 presided over the main project of successfully developing the laser phototypesetting system for Chinese characters, and output an octavo newspaper negative. Guangming Daily reported that a major breakthrough has been made in the research and application of Chinese character information processing technology ―― the main project of computer-laser Chinese character editing and typesetting system designed by China has been successfully developed.
198 1 year, China's first computer laser Chinese character phototypesetting system prototype (Huaguang No.1) passed the ministerial appraisal.
1985, the font generator and controller of high-resolution Chinese character font generator, typesetting machine and printer obtained two national patents (jointly obtained with Lv Zhimin, etc.). ), and Huaguang Ⅱ system passed the national appraisal and was put into operation in Xinhua News Agency, and was selected as 1985 Top Ten Scientific and Technological Achievements in China. Huaguang Ⅲ system came out, which was the first practical typesetting system in China, and won the first national invention exhibition award. Won the title of Beijing model worker. Awarded by the State Economic Council.
1987, as the sole inventor of "compressed representation of high-resolution glyphs in computers", obtained the European patent number EP0095536. Economic Daily took the lead in purchasing Huaguang Ⅲ phototypesetting system, and the world's first Chinese newspaper with computer version and full-page output was born. The successful development of Huaguang IV system completely changed the traditional publishing and printing industry in China, which lasted for hundreds of years. It is recognized as the second revolution of printing technology in China after Bi Sheng invented movable type printing. The system won the first prize of National Science and Technology Progress Award. Won the first Seize Shinfu Printing Award.
1988, Huaguang IV was put into mass production, and its performance was much better than that of Huaguang III due to the adoption of two special VLSI chips.
1989 "high-resolution glyph high-speed rotation method" won the national patent (with Lv Zhimin, etc.).
199 1 year, obtained three national patents (the same as Lu Zhimin), namely, highly integrated font generator and controller, method for generating inclined characters and rotating characters at any angle at high speed, and control device for imagesetter to output positive, negative and positive images suitable for single-channel and multi-channel scanning.
Huaguang IV system won the national special prize for major technical equipment achievements. Peking University Computer Research Institute and Peking University New Technology Company jointly launched a new generation of electronic publishing system-"Peking University Founder Electronic Publishing System" (namely Founder 9 1 system), which is the fifth generation product developed by Wang Xuan and his colleagues. Enjoy special government allowance.
1992 "a measure for Chinese character font generator to deal with stroke interleaving" and "a method for generating newspaper and book layout lattice by section" are two national patents. Led Peking University Computer Research Institute to successfully develop Founder color publishing system and put it into use in Macau Daily, which gave birth to the world's first Chinese color newspaper with integrated processing and output of color pictures and Chinese. It triggered the color technology innovation of China newspaper industry and publishing and printing industry. Led Peking University Computer Research Institute to successfully develop a new technology of remote transmission of newspaper pages by satellite in the form of page description language, which was first adopted by People's Daily, enabling China newspaper industry to skip newspaper fax machines and directly popularize the new technology of remote transmission of pages based on page description language, thus realizing national synchronization and printing with the same quality of newspaper distribution. Launched the first Chinese professional software based on MS Windows in China. Elected as an academician of China Academy of Sciences and a member of the 8th CPPCC. Design Method of Publishing Software (Tsinghua University Publishing House).
1993 instructed students to develop the world's first PostScript Level 2 Chinese page interpreter, launched the sixth generation product Founder 93 system with a special coprocessor chip, won the bid for Ming Pao in Hong Kong, and then quickly entered Hong Kong, Macao, Taiwan, Southeast Asia, North America and other places, occupying 80% of the overseas Chinese newspaper market so far.
1994, the computer management system of news gathering and editing process was successfully developed and adopted by Shenzhen Evening News, which triggered the technological innovation of "Farewell to Paper and Pen" in domestic newspaper industry.
