Anilox rollers are classified according to the materials coated or sprayed on their surface. There are mainly two types of chrome anilox rollers and ceramic anilox rollers.

Processing of chrome-plated anilox rolls The processing of chrome-plated anilox rolls usually includes three processes: roll body pre-processing, anilox processing and post-processing.

The anilox roller is a very precise mechanical part, and it is also the core component of the flexographic printing machine. Therefore, you must be careful during use to avoid bumps or damage. When installing or unloading the anilox roller, be sure to apply force evenly, handle it gently, and install the anilox roller in the supporting groove or remove it from the printing press. In the printing process, the pressure between the doctor blade and the anilox roller and the rubber roller and the anilox roller should be as small as possible to reduce the abrasion of the anilox roller. After stopping, the anilox roller must be separated from the rubber roller, otherwise, the anilox roller will be bent and deformed due to long-term unidirectional force, which will cause uneven ink transfer to the anilox roller. In addition, after each printing, the anilox roller must be carefully cleaned in time to prevent the pigment particles in the ink from drying up in the ink hole, causing the ink hole to be blocked and affecting printing production.

In flexographic printing, the role of the anilox roller is: the anilox roller is the core component of the flexographic printing machine, and it is responsible for evenly delivering a certain amount of ink to the printing plate.

On the surface of the anilox roller, there are many tiny cavities with the same shape evenly distributed. Generally we call them “inking holes”. It is these inking holes that play the role of ink storage, ink distribution and quantitative transfer during printing. The role of ink. The inking holes are generally carved along the direction of 45° to the axis. The partition wall between the inking holes is called the "mesh wall", and the area of ​​the net wall is related to the shape of the ink hole.

The number of lines of the anilox roller refers to the number of ink holes per unit length on the surface of the anilox roller. It is also one of the important parameters of the anilox roller. It also has a very important influence on the ink transfer performance of the anilox roller.
