Correct Use and Maintenance of Anilox Rolls in Flexographic Printing
In traditional multi-color letterpress and lithographic printing machines, the inking system consists of a series of rollers, including the ink fountain roller, ink transfer roller, ink distribution roller, ink oscillating roller, and ink form roller, among others, totaling up to twenty or more rollers. While this system generally meets the requirements for ink transfer, it struggles to maintain a constant ink supply. In contrast, flexographic printing machines utilize a short inking system, where the anilox roller provides a consistent and uniform ink supply through its engraved cells. The anilox roller plays a pivotal role in flexographic printing, and understanding its proper use and maintenance is crucial for avoiding operational errors, improving product quality, and enhancing production efficiency.
