In developed countries in Europe and America, the label printing market is quite mature. More than 90% of the labels on the market are printed by flexographic printing machines. In China, a few years ago, printing companies rarely used flexo printing machines (mainly narrow-width flexo printing machines) to professionally print and process labels. However, with the development of the domestic label market, the label industry is moving at a rate of more than 30% per year. Rapid growth, flexographic printing also represents the development trend of label printing has been increasingly popular.

Flexo printing has won more and more label printing users due to its stable ink volume control and excellent performance such as basically no color difference. The flexo technology suitable for label printing has the following characteristics:
1. As long as the line number and the ink storage capacity of the anilox roller remain unchanged, there is no color difference at any printing
2. The continuous ink supply of the anilox roller will not produce the ghost ghost when printing on the spot
3. Self-adhesive material suitable for the production of thin-film facial paper by UV printing
4. Short ink path ink transfer system is simple in structure, convenient for operation, maintenance and repair
5. The highest machine speed can reach 150m / min, high production efficiency
Domestic unit type flexo printing machine
Unit-type flexo printing machine is the most popular type in the world today. Its advantages are: the use of water-based ink, compliance with environmental requirements, strong back-end processing capabilities, saving labor, reducing waste, improving production efficiency and reducing costs; Roll-to-roll and roll-to-sheet, the function can be increased as needed, high flexibility; adapt to various printing, high flexibility; good color consistency; investment size is available, completely determined by the product; simple structure, operation Convenient, easy to maintain, etc. The installed capacity of unit-type flexo printing machines in China has shown a good growth in recent years (as shown in Figure 2):

From the investigation and analysis of flexo printing machine users, it is found that the installed capacity of imported equipment and domestic equipment on the domestic market has changed considerably in recent years (see Figure 3), indicating that the domestic flexo printing technology is gradually mature and It is increasingly used in the label printing market.
