Development history of ceramic anilox roller in flexo printing

Flexographic printing originated in the United States in 1938. The anilox on the roller is embossed, which is very rough. It is mainly used on the outer packaging of cartons (also known as industrial packaging), using iron rollers. However, it is found that the roller wear is very big, which makes the printing quality and printing cost difficult to guarantee.

In 1939, the anilox roller was plated with a hard layer of metal (such as chromium) on its outer surface, but it was still difficult to meet the requirements.

In 1970, it was proposed to use hard ceramics to make anilox rollers. However, it is very difficult to carve grooves on ceramics. Until 1984, the mature development of laser technology and the wide application of various industries. The laser anilox roller was officially adopted.

The laser engraving ceramic anilox roller

Early roller engraving form, using surface chrome plating, mechanical engraving, applied to slightly thick carton or plastic printing processing and coating. The printing effect of chrome plated anilox roller is not bad when it is used at the beginning, but the service life of the roller is very short because the metal surface is easy to wear. In addition, due to the limitation of the shape of the mechanical engraving mold, the number of lines can not be increased, and even can not meet the needs of medium grade flexographic printing. It is believed that with the passage of time, it will be gradually replaced by ceramic rollers.

CO2 laser engraving ceramic anilox roller

At present, most of the laser anilox roller engraving manufacturers use the traditional CO2 laser engraving technology. This type of effective screen cable is about 80-400 LPI, which can meet the basic principle of carton printing, and can print full tone and thick text. With the invention of laser ceramic anilox roller, the printing quality of flexographic printing has been greatly improved. However, due to the lack of clear dot and wide mesh, it is difficult to improve the screen line.

CO2 multiple engraving ceramic anilox roller

The most advanced CO2 laser engraving system can change the shortcomings of the traditional CO2 laser engraving, making the mesh very wide, forming more evenly, and expanding the mesh cable to 50 ~ 1000 LPI .

The above is the development of anilox roller in flexo printing, hoping to help you understand.
