The ten-year changes of the processing technology

  • Detail

The last five years of the 20th century and the first five years of the 21st century are the era when China's printing industry has undergone profound changes. It is also a period when the 28 word policy of "digital prepress, networking, multi-color printing, high efficiency, diversity and automation after printing, high-quality and serialization of equipment" has been proposed and actively implemented after the 16 word policy of "automatic Phototypesetting, electronic color separation, high-speed offset printing and binding linkage". During this period, the China printing and equipment industry association has played a role in promoting the coordinated development of China's printing, equipment, equipment and other related industries by holding forums, exhibitions, annual meetings and other forms. The exchanges between printing enterprises and equipment manufacturers and suppliers are also growing and closer. The progress of printing equipment and printing equipment industry has promoted the development of China's printing industry

there is no doubt that the post press processing, as an indispensable part of the printing industry, has also changed, resulting in twists and turns. It has developed rapidly in "post press diversity and automation", which has made substantial progress in the overall quality of Chinese books and packaging products. The requirements of the 28 character policy for the realization of "diversity and automation after printing" are: "widely adopt automatic and continuous equipment and means, gradually change the backward situation of manual processing and semi mechanized production, fundamentally improve the quality and production efficiency of final products, and strive to reach the general level of foreign advanced countries". In recent years, among the backbone printing enterprises in China, these goals have not only been achieved, but also exceeded. The level of post press processing can be said to have reached the upper middle level of advanced countries, rather than the general level. A large number of printed materials from these countries are processed in China and then sold back. If the investors in the printing industry have paid more attention to the investment and transformation of printing equipment with strong profitability for a considerable period of time, and despised or neglected the mechanization and automation transformation of post press equipment, this situation has been significantly improved in the past 10 years, especially in the first five years after entering the 21st century. Large book and periodical printing enterprises have been increasing their investment in post printing. Taking the large-scale wireless binding line that finally realizes the completion of books as an example, in 1999, Shanghai Zhonghua Printing Co., Ltd. invested nearly 2000 yuan. Therefore, the tensile testing machine for testing high molecular polymers has a certain difference from the common tensile testing machine for testing the tensile properties of materials. After the introduction of the trendy binding line and hardbound line produced by Martini company of Switzerland by similar enterprises nationwide, Germany's aorenberg Colbus and other large-scale glue binding lines have entered the mainland one by one, changing the situation in history that manual and small disk packaging equipment are the main production. The Shanghai Office of Martini company informed that the total number of glue binding lines produced by the company entering the mainland market after 1999 was no less than 100, which was unimaginable before. At the same time, the sewing machines produced by ASTA company in Italy and Martini company in Switzerland, MBO, stale made in Germany and Shoei folding machine made in Japan, Bola paper cutting machine made in Germany and horse riding nail binding lines produced by Heidelberg company in Germany and Martini company in Switzerland can be seen in more factories. The introduction and use of these equipment have greatly improved the quality of domestic publications

while overseas post press equipment has entered the Chinese market on a large scale, the production and sales of domestic post press equipment are even more successful. Purlux horse riding nail linkage line, disc wrapping machine, typesetter produced by Ziguang company under Shanghai printing and packaging machinery company, and folding machine manufactured by Zihong company 4.2.6 strain extensometer and accessories ★ 1) static accuracy: not greater than 0.5% of the indicated value; ★ 2) dynamic accuracy: no more than 1% of the indicated value; 3) Gauge length: 25mm; 4) Strain limitation: 10% of them are well-known among domestic book and periodical printing enterprises, and once there was a lively scene of tight production scheduling and users scrambling for purchase. In the 6th International Printing Exhibition held in Beijing in 2005, a large number of domestic manufacturers participated in the exhibition of post press equipment. The products displayed ranged from book binding equipment to gravure and silk printing equipment. Now, few small binding factories that specialize in post press processing do not have basic production equipment such as folding machine and disk wrapping machine. The situation of manual operation in history has been completely overturned. In addition to these basic binding equipment, some large-scale book printing enterprises have all kinds of auxiliary binding equipment, such as laminating, oiling, UV glazing, edge stamping, large-area bronzing, pattern die cutting, bump rolling, plastic packaging, and even gilding, rounding, punching and other auxiliary binding equipment, which can ensure to meet various processing requirements put forward by customers

in the past 10 years, book printing enterprises have gradually embarked on the road of post press processing automation and continuous production. Although the profit situation is also declining year by year, the packaging printing enterprises that are still far better than the book printing industry have done better in post press diversification and automation. Tobacco printing enterprises should be the best among them. The outer packaging of high-grade cigarettes is extremely useful in process application, including bronzing, concave convex and anti-counterfeiting. In the box making and forming section, the international top Bobst die-cutting machine and box making machine are widely used in production, which is no longer rare. As for the printing enterprises undertaking drug packaging, wine packaging and cosmetics packaging, the proportion of continuous and automatic production is also quite high due to the high added value and large batch of their products and the extensive use of advanced post press processing equipment

in a word, at the end of the last century, the requirement of "post press diversity and automation" in the 28 character policy proposed after repeated deliberation was no longer a matter to be pushed forward, but a matter that has been generally realized in post-processing enterprises with a certain scale

it took a short time to complete the essential improvement of the post press processing equipment. The fundamental driving force lies in the requirements of the market. The serious lag of book binding in the 1990s once became the focus of quality problems. At that time, Vice Premier Li Lanqing, who was in charge of cultural and educational work, also used the unqualified teaching materials received by his grandson.
