What Is Flexographic Printing Machine?

A flexographic printing press is a machine that uses a flexible printing plate and transfers ink through an anilox roller to complete the printing process.

1. Working principle
The flexographic printing press uses a highly fluid fluid ink. The ink is transferred to the image and text part of the printing plate by the ink fountain rubber roller and the anilox roller and inked. Then the printing pressure is applied by the pressure roller to transfer the ink on the printing plate to the substrate. Finally, the printing process is completed after drying.

2. Structural features
The machine structure is simple: the structure of the flexographic printing press is relatively simple, so it is easy to operate and the maintenance cost is relatively low.
The ink delivery system is simple: the anilox roller is used for ink delivery and ink transfer, which eliminates the complex ink delivery roller group, and the ink delivery control response is faster.
Diverse printing units: There are many types of flexographic printing presses, such as shelf type, satellite type and unit type. Among them, each printing unit of the satellite flexographic printing press is installed between two wall panels around a common impression roller. The substrate is printed around the common impression roller for color printing. It has the characteristics of direct gear transmission, accurate registration, and stable printing process.
3. Printing characteristics
Simple plate making: The plate making process of flexographic printing is relatively simple, and the plate cylinder can be loaded, proofed and registered outside the machine.
Strong wear resistance: The flexible relief has low pressure and strong wear resistance. The printing life can generally reach 800,000 prints, and can reach more than one million prints. The number of plate changes can be reduced for large-scale printing.
Quick drying: When using alcohol-soluble ink to print on plastic film, the ink layer can dry quickly because the ink has a large volatility and uses a hot air drying device.
Strong adaptability: The flexographic printing machine can be connected and matched with various post-processing machinery to form an assembly line to improve labor productivity. At the same time, flexographic printing has a wide range of adaptability to substrates. It is not only suitable for printing on various packaging materials, but also suitable for printing on ultra-thin, extremely smooth materials and ultra-thick, rough materials.
IV. Application field
Flexographic printing machines are widely used in packaging printing, label printing, book printing, advertising printing and other fields. It can print various types of packaging materials, such as paper, plastic, metal, etc., and can also print various types of labels, such as self-adhesive labels, paper labels, etc. At the same time, the flexographic printing machine can also print on various types of materials, such as paper, plastic bags, metal foil, textiles, etc.
