DRUPA 2OOO demonstrates the new technology and development prospects of the future print media, and also puts forward new requirements for the post-press process reform. In order to completely change the backwardness after printing, promote post-printing process reform and technological innovation, and quickly improve the level of post-press processing, the Postpress Technology Innovation Center, China Baoxie Paper Products Information Center, Zhengdatian New Materials Research Institute, and Henan The “Printing Technology Innovation Market Seminar†jointly held by the Provincial Printing Binding Technology Plant was held in Suichuan, Henan Province from September 1st to 5th, 2000. Representatives from the printing, packaging production and processing, equipment and equipment manufacturing and supply, research, teaching, information and other industries and the post-press technology innovation promotion and application market attended the seminar.
The meeting analyzed several features of the unbalanced development of the current printing industry technology:
First, the structure of the printing industry has grown from commercial newspapers and other media to commercial printing. Commercial advertising, forms, and packaging have gradually become the mainstay of printing. The number of policy-oriented newspapers and periodicals has reduced the print output of such publications, resulting in fixed-point printers at all levels of books and periodicals. It is also a difficult step for China's printing pillar companies. The rapidly-developing emerging printing companies with commercial printing as the main body are also positioned. Accurate, advanced equipment, reliable quality, efficient and efficient service, and other advantages, has emerged as an important pillar of the printing industry, occupies a new printing market.
Second, due to various reasons such as science and technology, economic information exchange, and prediction of future development trends, the overall layout of the printing industry is that the technological innovation in coastal open areas is obviously better than inland, especially in the west. The trend of “living in and out of the country†and “Northern Living and South Indian†have continued unabated.
Third, in the process of technological advancement, there is a significant gap in the speed of prepress, printing, and postpress of the printing industry. With the rapid development of the computer industry and the popularization of Internet technology in the world, the printing and publishing industry has been affected by digitalization and networking as a traditional information industry. When China's electronic laser photocopying and discharging system reached the international advanced level, prepress has begun to adopt advanced information absorption, storage and transportation technologies. Editing work is automated, and communication and data exchange can be conducted with relevant organizations at home and abroad. Super-XH100 satellite news picture transmission processing system has been completed by Xi'an Jiaotong University and Xinhua News Agency. Through the combination of hardware and software technology and multi-level, multi-mode program development means, the prepress information transmission has reached the level of automation and intelligence. The rapid development of multi-color offset printing in various printing companies has already taken shape in China's printing industry. Fast printing, personalized printing, and on-demand printing have become new trends in the printing industry under the development of market economy.
Compared with the rapid development of prepress and printing, labor-intensive printing is even more backward. Extensive type of postpress processing is still based on manual labor or semi-mechanized operation. Obviously affect the quality of high-speed, fine print, restricting the overall rapid development of the printing industry.
The meeting discussed the basic situation and major issues after printing:
First, post-press processing in the printing of books and magazines is mainly focused on the binding process; in terms of packaging and printing performance for the film, coating, die-cutting, indentation, hot stamping and other aluminum technology. More often than not, post-press finishing and book printing are compatible and compatible.
Second, the binding process due to the process design and implementation, production operations and coordination, equipment, technical performance and maintenance, material quality determination and selection and other factors, not only the existence of low production efficiency, but also obvious quality problems. According to the statistics of relevant departments, the reason for the unsatisfactory quality of books and periodicals printing is that more than 60% of them are due to binding.
Third, film, glazing as the conventional process of finishing the surface after printing, there is a common production process in the production process of pollution, prone to fire, the traditional after the coating is wet and easy to blistering and filming , warping and other issues. Solvent-based, UV-type coating is prone to problems such as color printing or disappearance of metallic color. At the same time, the film coating and polishing products processed by this traditional production process all have odor migration and affect the later issues of the quality of the packaged goods.
Fourth, the hot stamping of electro-aluminum is the development of gilding finishing to multi-color, multi-layout, new material direction. At present, there are problems such as color fading, color fading, and color loss after laminating and electro-aluminization. There are also new problems that can easily come off after stamping anodized aluminum on super bright card paper.
V. The main reasons for the existence of various problems after printing can be summarized as follows:
1. The process behind the 1 binding process is still based on the manual work of iron wire. The unavoidable arbitrariness of the manual operation of the complex procedures from the inside leaflet to the hot back book is a gene that is difficult to guarantee the development and quality of productivity.
The coating equipment introduced in the 280s was a rubber compound machine. This process is the result of a large amount of pollution generated in the process of production, which is detrimental to the physical and mental health of operators, and destroys the cleanliness of the surrounding environment; it is extremely prone to sudden fires and does not provide reliable guarantees for safe production; products that are prone to large quantities after film coating Foaming, filming quality accidents; after the film is prone to odor migration caused by the residual organic solvent volatilization, so that the inner package of goods odor deterioration of various problems fundamental.
3 coating process both coating - calendering process, but also UV coating process. The drying technology of the liquid coating coating to the solid state conversion makes it impossible to dry the interior of the coating when the surface is dry, and the internal drying of the coating further affects the color of the printing ink layer and changes the problem.
