Characteristics and future trends of the three major packaging printing methods (Part 2)

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

1. Existing understanding and specific problems: after the 1970s, flexographic printing has matured and developed rapidly in technology internationally. 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. In the 1980s, few flexographic presses that entered RI really played a full role. In the middle and late 1990s, China introduced more foreign flexographic printing machines. At the same time, the flexographic printing machines developed by our country gradually matured, but due to the poor grasp of the printing process. The flexographic press selected by some users is not suitable for the prints they are preparing to print

2. The domestic localization production of flexographic plates and raw and auxiliary materials has a long way to go: at present, most of them still rely on RI. 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 the right equipment and prints: flexo printing can not only play its specialty in the field of packaging printing, but also play a role in the printing of books, periodicals and newspapers with excellent film forming ability. Flexographic printing has its uniqueness in packaging printing, and has formed a consensus in the printing industry. In packaging and printing, corrugated board printing can give full play to the advantages of flexo printing. In foreign countries, 85 - 98% of the corrugated board with a temperature of no more than 1 ℃/m or a total maximum of 2.2 ℃ (the experimental sample does not work) "is printed on the flexographic press. 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 30l-h4o%, and the development of countries is different. Flexographic printing should be used first in the most suitable prints for flexographic printing. According to the specific requirements of these prints, choose the most appropriate flexo printing machine

(III) how to speed up the development and get out of the misunderstanding. Flexographic printing has a wide range of printing, but not everything can be printed by a machine. Like other printing methods, each machine has a specific printing range. Even flexo printing machines in a specific ei]j~l 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, Jinan experimental machine factory understands that "he Erdogan was elected president of Turkey", and has different requirements for the quality of printing. 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 broad prospects for development

2. Seriously solve the production and quality problems of flexographic plates and other raw and auxiliary materials. Through cooperation with foreign countries and our own strength, we should improve the localized production and quality of flexo plates and other raw and auxiliary materials as soon as possible. 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 flexo printing has many variables, it is difficult to realize standardization and digitization. However, on the basis of constantly summarizing and using good enterprise experience, we should optimize the operating 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
