Editor's note: China's printing industry entered a period of rapid development in the late 20th century. Relying on the promotion from high-tech international printing. Especially in recent years, with the maturity and perfection of CTP technology, Chinese printing is entering the era of thermal and violet laser from silver salt. However, this step is somewhat hesitant, staggering and even puzzled. What is the prospect of CTP technology in the printing market? In the face of harsh and fierce market competition. How can Chinese printing companies use the internationally advanced technical force to find a road to technological innovation and market breakthrough suitable for their own development? As a world-renowned plate material supplier. Fuji Starlight always leads in the field of CTP equipment and plate materials. Not long ago, the company organized a group of experts from the front line of printing production with rich practical experience and superb theoretical level, aiming at the problems and phenomena encountered in the application of high and new technology. Conduct face-to-face explanations and exchanges with the technical staff of the printing enterprise, blowing a warm breeze for the printing enterprise. Pre-press digital management of brilliant plate making Tian Junshan The assistant general manager of Hong Kong Bright Platemaking graduated from the Department of Printing of the Hong Kong Polytechnic Institute in 1991 and has been engaged in printing for 15 years (13 years in Guanghui) The pre-press color reproduction process of Hong Kong Bright Platemaking Co., Ltd. (BA) is: first check the color reproduction, and then perform scanning and color control, document production, and screening. BA has PrinergyRIP (raster graphics processor) and deltaRIP, and the output part has CTP and CTF, as well as color correction, traditional drafting, and digital drafting. All production processes are based on world standards. I think that before color reproduction, color measurement must be done first. There are three basic factors: vision, light source and light reflection and absorption. Requires quality controllers, color separation controllers, color correction controllers, and even drafting controllers to have normal visual judgment. BA regularly uses a light meter and color temperature meter to measure color temperature and luminosity, and enters the light source data collected by the spectrophotometer into a computer for analysis. Obtain a standard light source. Because different inks have different light absorption and reflection in different wavelength bands in the spectrum, the same printed matter produces different color effects under different light sources. By mastering the color characteristics of the ink, the actual printing and printing can be evaluated and predicted. Color reproduction ability. Secondly, the data management of the color reproduction part should be done. Electronic color separation is a very important part of color reproduction. If different types and quality are different, it will directly affect the quality and effect of the printed matter. Therefore, management and operation personnel must have the art, photography and color reproduction theory in order to get perfect color reproduction. Standardization and data management are necessary, but for the gray balance, color balance, correct contrast and the best clarity of the manuscript, in addition to the data specification, there must be a stable and optimal copy test tool. BA has a remote digital proofing system. As long as there are 2 digital proofing machines, the files can be transferred to overseas customers for simultaneous proofing and color proofing. BA uses CTP as a professional publishing draft, because all the equipment, processes, technology and raw materials of CTP wet drafting are roughly the same as those of printing presses, so they can provide very close effects. [NextPage] Management of FM net and high net line printing technology Miyabe Rikohiko Fuji China's Minister of Graphic Arts and Technology, graduated from Kyushu University of Science and Technology in 1983, joined Fuji Photographic Film Company in 1983, and served as the research and development of horizontal and photopolymerizable CTP plates at the Institute of Printing Materials. Planning, overseas technical support work With the popularity of CTP and the acceleration of computer processing speed, as well as the continuous improvement of FM network generation system and technology, more and more customers began to pay attention to FM network and high-definition AM network. However, realizing high-definition printing is not that simple. Before using this technology, customers must understand the difficulties in using these technologies and how to overcome them. I first introduce the characteristics of the FM network. The advantage of the FM network is that you can't see moiré patterns, rose spots, and no broken wires. No jagged pattern, good detail reproduction ability, compared with its color saturation is also significantly improved. Advertisers often appoint printers to use FM networks to make printed products have more perfect advertising effects. For packaging and printing, customers prefer to give people a high-level enjoyment, especially art printing and photo printing. In order to give a high-grade feeling, customers often specify the use of FM screen printing. What are the problems when using FM network? First of all, the unevenness produced by the printing machine is more obvious when FM network printing. Especially outdated printing presses are more prominent. In the printing process, children's skin and women's delicate skin are reproduced. We often have headaches. There are also water and ink balance problems, ink pile problems and so on. This requires strict preparations for printing. The main countermeasures are: 1. For those who use the AM network and change it to the FM network, the plate-making machine must be readjusted, including adjusting Fo-cus, exposure, exposure mode, and curve correction. Second, fundamentally improve the development conditions, including the management of the conductivity of the developer, the selection and regular maintenance of the developer. Strictly speaking, the original thermal plate processor can not automatically manage the conductivity, and Fuji's thermal plate processor (FLH-Z85 / 125) has a super replenishment device, which can extend the life of the developer by 4 times and achieve quality It is stable and can run for a long time. 3. Improve printing conditions, including selecting excellent inks and fountain solutions. Fourth, choose FM or AM high-definition printing. It should be noted that the effect of the 20-micron FM network and the 450LPI AM network is the same, and because 300LPI is easy to implement, it is more likely to win in terms of quality. The high-precision amplitude modulation network (that is, screening with more than 300LPI) technology requires lower printing conditions than the FM network. The moire, rose spots, broken lines, and zigzags that appear at 175LPI are not visible in high-definition printing of more than 300LPI, and those skin irregularities that are likely to occur during FM network are at high Fine amplitude modulation online is also not available. Referring to the practice of the Japanese newspaper industry, FM networks are often used for graphic advertisements in newspapers, and AM networks are often used for text parts. [NextPage] Artron's road to standardization Gurnon Technical Director of Artron Enterprise (Group) Co., Ltd. Mainly responsible for the technical innovation, technical research and development and technical management of the group company, including the formulation and promotion of enterprise technical standards; the innovation and introduction of production and technical equipment: and the development of new technologies, new processes and new projects in line with the group's development strategy. Established Yachang Company in Shenzhen in 1993. In 1999, he cooperated with Beijing Printing Institute to establish Beijing Yachang Company. In 1997, the European printing technology expert was hired as the technical consultant of Artron. In 2001, he successfully printed the Beijing Olympic bid report. In 2002, he became the printer of the Shanghai World Expo 2010 bid. Airport Yachang Building was completed and put into use in 2004. In November 2006, Shanghai Artron Corporation was established. Yachang's business philosophy: to promote commercial printing with art printing. Artron's business market is divided into art market, commercial market and overseas market. At the beginning of its founding, Artron proposed to achieve digitalization, standardization and standardization in management and technology. Yachang's standardization has three aspects: one is the management system, the other is the control of the production process, and the third is the result of the standardization work. Artron has passed the ISO9000 quality system certification. In 2007, it plans to complete the ISO14001 environment and OHSAS18000 occupational safety and health management system certification. Artron has always paid attention to the use of scientific methods to control the production process. Since 1998, it has implemented fine management models such as TPM printing comprehensive production and maintenance, 5S, TQM overall quality management, and 6 Sigma management. Artron designed a quality planning book to meet the individual requirements of customers. In order to ensure that it can maintain good resolution on the printed version, Artron used the CTP version of Fuji Star. Yachang's operation manual is also called standard operating procedures, which uses a combination of graphics and text to specify the time standard for each operation. Artron has strict determination of ink and water. Artron uses the TPM (Printing Total Maintenance System), which is divided into three parts: one is to edit the checklist; two is to measure and test the components; the third is to review. In the course of more than ten years of development, Yachang has formed a unique standard system of Yachang. These standards have strong versatility and reproducibility, and are particularly suitable for the needs of Yachang's group development management. Yachang's technical manual includes four aspects, one is the technical standard, the other is the quality standard, the third is the operation standard, and the fourth is the maintenance standard. Standardized production has brought rich results to Yachang-in 1998, Yachang's finished product pass rate was less than 92%, and in 2002 it reached 95%. In terms of production efficiency, the average operating rate of Artron's printing equipment was 26% in 2002, but it reached 42% in 2005, that is, printing efficiency increased by 60% in 4 years. In 2005, Artron established China's printing standardization technology application research and promotion base. In 2006, Artron Art Network has become the largest professional website for artworks in China, with daily visits of up to 3 million. At the same time, Artron established the first data publishing standard from printing to the Internet in China, and achieved cross-platform printing data publishing.
