Zecher GmbH has recently presented Zecher C.P.T. (Cell Polish Treatment) engraving technology. The company says this innovative optimisation method revolutionises the surface treatment of ceramic anilox rollers and sleeves and raises print quality to a new level.
Zecher C.P.T. is a thermal finishing process that is carried out after laser engraving. The process-related sub-microscopic irregularities, such as pores and nano-cracks, which occur during engraving, are thermally eliminated using a new process. This short but precise thermal treatment ensures a ‘polished’ cell structure and strengthens the mechanical stability of the roller surface.
