1.Consider the printing or coating material: Different materials have different absorption and adhesion properties for ink or coating. It is necessary to select an anilox roller with appropriate mesh depth and opening rate according to the characteristics of the material. For example, for paper with strong absorption, an anilox roller with deeper mesh depth and larger opening rate can be selected to ensure sufficient ink transfer; while for non-absorbent plastic film, an anilox roller with shallower mesh depth and smaller opening rate needs to be selected to avoid excessive ink transfer leading to plate paste or poor drying.
2.According to the printing or coating process: the process parameters such as printing or coating speed and pressure will also affect the selection of anilox roller. In the process of high-speed printing or coating, the anilox roller needs to have good ink release performance and fast ink transfer speed. An anilox roller with a larger mesh angle and a cell shape that is conducive to ink flow can be selected; in some fine printing or coating processes that require precise control of the amount of ink, an anilox roller with high mesh accuracy and accurate cell volume needs to be selected.
3.Combined with the characteristics of ink or coating: the viscosity and drying speed of ink or coating are also important factors in selecting anilox rollers. High-viscosity inks require a larger cell volume to accommodate and transfer, so you can choose an anilox roller with a deeper mesh depth and larger cell openings. For inks that dry faster, you need to choose an anilox roller that can release the ink quickly to avoid drying and clogging of the ink in the cells.
