The development of packaging and printing methods (below)

(B) The main reasons for the slow development of flexo printing in China 1. Existing understanding and specific issues: After the 1970s, it was at the international level that flexo printing was rapidly and technologically mature. At that time, China was vigorously advocating the development of offset printing. The development of offset printing is undoubtedly correct, but there is little publicity for flexo printing. Many people in China know little about flexo printing. Plus, printers know little about flexo printing. As a result, the flexographic presses imported in the 1980s were rarely fully functional. In the middle and late 1990s, China introduced more foreign flexo presses. At the same time, China's own developed flexographic presses gradually matured. However, due to the poor mastery of the printing process, some of the flexographic presses purchased by users were not suitable for them. Printed prints.
2. Domestic production of flexographic plates and raw and auxiliary materials has a long way to go: Currently, most of them rely on imports. This is an important reason for increasing the cost of flexo printing.
3. The requirements for flexo printing are unreasonable: At present, domestic flexographic printing machines, whether they are imported or domestic, basically belong to middle and low grade products. In addition, domestic flexo printing technology is still not fully passed, and its printing products are of medium and low grades. Many people are unreasonable to compare these printed products with higher-grade offset and intaglio printing products. Experience abroad has long proved that flexo printing can print high-grade prints. However, there must be corresponding equipment and corresponding plates, raw and auxiliary materials as well as mature processes and high-level operators.
4, choose the right equipment and print: Flexo can not only play a specialty in the field of packaging and printing, but also can play a full role in the printing of books and newspapers. Flexo printing has its own uniqueness in packaging printing, and a consensus has been formed in the printing industry. Corrugated paper printing in package printing can best develop flexographic features. 85%-98% foreign corrugated board is printed on a flexo press. Label printing is also the strong point of flexographic printing. The proportion of developed countries that use flexo printing is 85%-90%, and it is also developing rapidly in China. Flexible packaging printing is the main competition place for flexo and gravure printing, and the development of each country is also different. Carton printing has the competitions of offset printing, flexo printing and gravure printing. The flexographic printing in the United States is 30%-40%, and the development situation in different countries is different. The flexographic printing should be used first in the prints that are most suitable for flexo printing, and the most appropriate flexo press is selected according to the specific requirements of these printed products.
(C) how to accelerate the development of 1, out of misunderstandings. Although flexo printing has a wide range of printing, it is not a single machine that can print anything. It is the same as other printing methods, each machine has a specific printing range. Even a certain printing range flexo press has high, medium and low grades. This is the first problem that should be solved. Second, we should give full play to the speciality of flexo printing, instead of comparing it with other printing methods. It is not possible to compare blindly with other printing methods regardless of the level of equipment, raw and auxiliary materials and printing technology. Third, we should carefully analyze the reasons for the current problems of flexo printing, and propose solutions to existing problems. Fourth, the requirements for quality should be appropriate. People have different requirements for quality of life. Similarly, there are different requirements for print quality. In particular, packaging printing, whether it is needed or not, requires high-precision printing, which is probably one of the manifestations of over-packaging in China. The development of flexographic printing in our country is relatively late. At present, it accounts for about 5% of packaging printing. It should have a broad prospect of distribution.
2. Seriously solve the problems of production and quality of flexographic plate and other raw and auxiliary materials. The local production and quality of flexographic plates and other raw and auxiliary materials should be improved as soon as possible through cooperation with foreign countries and our own. In order to solve the problem of the high cost of flexo printing, the current large number of imports. The cost issue is the key to the survival and development of flexo printing.
3. As soon as possible to solve the problem of flexo printing standardization and data. Although there are many variables in flexo printing, it is difficult to achieve standardization and dataization. However, we should continue to summarize the use of better corporate experience, based on the optimization of the operating procedures and selected data for each printing process of different prints to form a consensus. First, we will form enterprise standards and gradually form industry standards. Flexo printing involves a variety of different substrates and inks, and we can form different standards one by one. Without solving this problem, flexographic mass production and stability are difficult to solve.
4, as soon as possible to cultivate qualified flexo platemaking, printing talent.
