Anilox rollers are made of metal or ceramic, and the surface of the roller is mechanically or optically engraved with many cavities also called anilox. The surface of the anilox roller is made with ink cavities and mesh walls as the ink transfer roller for the quantitative ink supply of flexographic printing. On the surface of the anilox roller, there are many tiny concave holes of uniform shape, which we generally call "inking holes", and it is these inking holes that play the role of ink storage, ink leveling and quantitative ink transfer in printing. The inking holes are generally carved along the axis at 45°, and the wall between the inking holes is called "anilox wall", and the area of the wall follows the shape of the inking holes. Anilox rollers have the following three important parameters.
Product Classification
Anilox rolls are classified according to their surface coating or spraying materials, there are mainly two kinds of chrome plated anilox rolls and ceramic anilox rolls. Processing of chrome-plated anilox rolls The processing of chrome-plated anilox rolls usually includes three processes: pre-processing of roll body, anilox processing and post-treatment.
Method
1, According to the number of mesh lines of the printing plate selection 2,Choose according to the graphic structure For the same anilox engraving process, the higher the number of lines, the less ink transfer, more suitable for printing dots and small text; and the lower the number of lines, the more ink transfer, more suitable for printing large color blocks and bold characters. 3, According to the substrate selection When the substrate surface is rough and the ink transfer is large, it needs to use the anilox roller with less number of lines; on the contrary, the smooth surface of the printed substrate should use the anilox roller with more lines and less ink transfer. 4,Choose anilox rollers according to different degree of wear: when the volume of inking hole of anilox rollers is reduced by half, it should be replaced by new ones. 5,Choose anilox rollers according to different ink transfer devices
