1. A cleaning procedure for an anilox roller, the cleaning procedure comprising the steps of:
generating a laser beam by using a resonator;
defocusing the laser beam by using a lens, wherein the defocusing step increases a diameter of laser spots on a surface of the anilox roller;
redirecting the increased diameter laser beam by using a galvo mirror,
wherein the laser beam is redirected to a cleaning-active zone on the surface of the anilox roller such that the laser spots hitting the surface of the anilox roller partially overlap in a linear direction corresponding to an advancement of the laser beam and in a circumferential direction corresponding to a turning direction of the anilox roller simulating a continuous pulse of the laser beam.
