The main purpose in laser engraving anilox rolls is to produce cells that will dispense ink properly without clogging or smearing, while providing the converter with improved quality and long roll life.

To understand the laser-engraving process, one must take a little trip back to science class. Most people, at some point during their education, have learned about the light spectrum—one end is ultraviolet light and the other is infrared. In between, there are varying degrees of light energy. The CO2 and YAG lasers use light energy from the infrared spectrum, and the degree to which they use this energy impacts the engraving process.
