What information do you get from the Flexo printing machine?

Flexo printing machine is a printing process where colour is transferred by grid rollers. Flexo printing machines generally use light sensitive resin plates with a thickness of 1-5 mm. Inks are divided into three categories: water-based inks, alcohol-soluble inks and UV inks. As the ink used in flexographic printing is environmentally friendly, it is often used in food packaging printing and has a bright future. The flexographic printing is a kind of relief printing.

What is the development history of Flexo printing machine?

Flexo printing machine was originally called flexo printing. It originated in the United States in the early 1920s. Because of its toxic aniline dye ink, it was not developed. After the mid-1970s, due to the progress of the material industry, especially the advent of polymer resin plates and cermet anilox rollers, the development of Flexo printing machine has made a qualitative leap, becoming the fastest growing in the world The printing method, especially in the United States, has been fully developed. Both the manufacturing technology of the printing machine and the application technology of flexo printing represent the highest level of Flexo printing machine. Most of the commodity packaging seen in the US domestic market is almost all flexographic printing products. According to statistics, in the United States, the market share of flexographic printing is 70% in flexible packaging printing; 85% in label printing; 98% in corrugated box printing; and 25% in carton printing.

How to clean Flexo printing machine with ultrasonic?

The anilox roller of the Flexo printing machine is immersed in a tank of an ultrasonic cleaning system filled with a chemical cleaning solution. The frequency conversion device in the tank sends high-frequency sound waves. The solution vibrates and generates bubbles. The dry ink, resin, and coating in the ink cavity Under the combined action of the vibration of the solution and the inward explosive force generated by the directional explosion surface of the bubble, the material flows away from the ink cavity and flows away with the cleaning liquid. The cleaning time depends on the size of the roller and the ink blocking condition, generally 0.5-24h. During this time, the anilox roller will be exposed to high-frequency ultrasonic vibration for a long time, which will destroy the ceramic layer, which will definitely cause certain damage to the ink layer of the anilox roller and the ink cavity. In addition, this method occupies a large area, high investment cost, and complex process. Although it has a certain cleaning effect, whether this method is perfect or not still needs actual testing.

How to correctly understand Flexo printing machine?

Flexo printing machine has its own unique process characteristics. From pattern design to color selection, it should highlight the strengths of flexo printing and avoid the weaknesses of flexo printing. In addition, conceptual issues are also issues that restrict the development of Flexo printing machine. In the past few years, there were two extreme opinions. One said that flexo printing is too good, and it will replace gravure printing in the future, or even offset printing; second, flexo printing is too bad and can only print very poor products. These statements are biased, and the correct positioning of flexo printing should be: a low-input, high-output applicable technology in the packaging and printing field. Only by finding the positioning of flexo printing can the positioning of the market be found.
