Laser engraved anilox rolls

Higher screen counts require higher anilox cell counts—more engraving lines per inch. More cells mean smaller cells. Smaller cells present an order of magnitude more problems both to manufacture and in use. Praxair's solution for that requirement is to use a YAG laser, which the company says can produce engravings of much higher volumes at much higher line counts (see illustrations) over a CO2 laser.
