B.E.L’s established Anilox Alpha Laser technology is the natural choice. High peak power and beam quality, pulse widths in the range of a few tens of nanoseconds and limited beam divergence. When laser engraving ceramics cells the Alpha Range produces smooth walls, flat bottom and near zero taper allowing a free flowing ink release from the Aniox Roller, for high quality flexo printing.

Anilox LTT laser technology has opened up a new perspective for flexography. It gives a predetermined volume from the Anilox Roller or Sleeve with double the number of cells to the printing plate. Therefore providing an even coat weight with superior control for combination printing.

The fundamental difference lies in the approach. The Anilox LTT rollers are laser engraved with a different cell structure than in conventional methods. Two different size cells are engraved adjacent to each other with different depth and surface technology. In this formation the ink transfer occurs unaided as a coating from the Anilox cells. The LTT laser engraving technique thereby makes use of the law of physics, which states that a large drop of ink has a different surface tension to a smaller adjacent drop. This is where the LTT strength lies. When the surface is covered evenly, the smaller ink droplets flow more easily into the larger ones. This process does not work as well when the droplets are the same size, as they are with the regular 60 degree cell structure.

C02 LASER ENGRAVING as the name suggests uses carbon dioxide, other gases, as in Helium (HE) and Nitrogen (N2) are combined to generate the laser light or beam. Specially made lenses to focus the beam, for the best engraving results are essential, to maintain the geometric consistency of BEL’s Laser Engraved Ceramic Anilox Rollers and Sleeves.
