As the heart of Flexography, laser engraving ceramic anilox roll requires that the diameter and depth of each cell is changeable, and the distribution of cell should be 30-hexagon, 45-quadrangle or 60-hexagon. By modulating the laser cavity gain from step way to gradual chang way, the wave modulating technology of high repetition light pulse solves the problem of increasing absorbency of ceramic to YAG laser. By engraving the same cell with grouped light pulses, the technology of high repetition and grouped pulses solves the problem of engraving high depth cell. By detecting with corder and processing using alterable divider coefficient, the technology of tow-dimension controllable distribution solves the problems of orientation and distribution of each cell. These three YAG laser texturing technologies above-mentioned are the key technologies to realize YAG laser engraving ceramic anilox roll.
