Current situation and development of packaging and printing (Part 2)

4. Low cost. The low cost of flexo printing has formed a broad consensus abroad, and there is still debate in China. The main reason is that most of the flexo printing machines, flexo plates and flexo inks used in domestic flexo printing rely on imports, resulting in higher costs. The cost of offset printing and gravure printing in this regard is relatively low. With the localized production of flexo printing equipment, plates and raw and auxiliary materials in China, the cost will be gradually reduced

(II) the main reasons for the slow development of flexographic printing in China

1. There are cognition and specific problems: after the 1970s, the technology of flexographic printing has matured and developed rapidly in the world. At that time, China was fully advocating the development of offset printing. It is undoubtedly right to develop offset printing, but there is little publicity for flexo printing, and many people in China know little about flexo printing. In addition, printing workers know less about flexographic printing technology. Therefore, few flexo printing machines imported in the 1980s really played a full role. In the middle and late 1990s, China introduced more foreign flexo printing machines, and the flexo printing machines developed by our country gradually matured. However, due to the poor grasp of the printing process, the flexo printing machines selected by some users are not suitable for the prints they are preparing to print

2. Domestic localized production of flexographic plates and raw and auxiliary materials has a long way to go: at present, most of them still rely on imports. This is an important reason to increase the cost of flexo printing

3. Unreasonable requirements for flexo printing: at present, domestic flexo printing machines, whether imported or domestic, are basically medium and low-grade products. In addition, the domestic flexo printing process is still not completely qualified at present, and its prints are of course medium and low-grade. Many people compare these prints with higher-grade offset and gravure prints, which is unreasonable. Foreign experience has long proved that flexographic printing can print high-end prints. However, there must be corresponding equipment, plates, raw and auxiliary materials, mature technology and high-level operators

4. Choose appropriate equipment and prints: flexographic printing can not only play a special role in the field of packaging and printing, but also play a full role in the coordinated development of unstoppable books, periodicals and newspaper printing. Flexographic printing has its uniqueness in packaging printing, and has formed a consensus in the printing industry. Corrugated paper printing is the best way to develop flexographic printing. In foreign countries, 85-98% of corrugated board is printed on flexo printing machines. Label printing is also the strength of flexo printing. In developed countries, the proportion of flexo printing is 85-90%, and it is also developing rapidly in China. Flexible packaging printing is the main competitive place of flexo printing and gravure printing, and the development of countries is also different. There is competition among offset printing, flexo printing and gravure printing in carton printing. Flexo printing in the United States is 30-40%, and the development situation of various countries is different. Flexographic printing should be used first among the most suitable prints for flexographic printing, and the most suitable flexographic machine should be selected according to the specific requirements of these prints

(III) how to speed up development

1, get out of the misunderstanding. Flexographic printing has a wide range in rainy season, but not everything can be printed by a machine

like other printing methods, each machine has a specific printing range. Even the flexographic press in a specific printing range can be divided into high, medium and low grades. This is the first problem to be solved. Second, we should give full play to the advantages of flexographic printing, rather than compare it with other printing methods. We cannot blindly compare with other printing methods regardless of the equipment grade, 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 the existing problems. Fourth, the requirements for quality should be appropriate. People have different requirements for the quality of life. Similarly, they also have different requirements for the quality of printing in the central laboratory. In particular, packaging and printing, whether required or not, requires high-precision printing, which is probably one of the manifestations of excessive packaging in China. The development of flexo printing in China is relatively late, accounting for about 5% of packaging printing at present, which should have a broad development prospect

2. Seriously solve the production and quality problems of flexographic plates and other raw and auxiliary materials

we should improve the localized production and quality of flexographic plates and other raw and auxiliary materials as soon as possible through cooperation with foreign countries and our own strength. In order to solve the problem of high cost of flexographic printing due to a large number of imports at present. Cost is the key to the survival and development of flexo printing

3. Solve the standardization and digitization of flexo printing as soon as possible

although flexographic printing realizes the variation of excitation amplitude by controlling the axial movement of 2D excitation valve, it is difficult to realize standardization and digitization. However, on the basis of constantly summarizing and using good enterprise experience, we should optimize the operation procedures and selected data of each printing process of different prints to form a consensus. First form enterprise standards, and then 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, it is difficult to solve the problem of mass production, stability and reliability of flexo printing

4. Cultivate qualified flexo plate making and printing talents as soon as possible
