In Flexoprinting the acceleration of printing speed is the driving force to use more and more lightweight aniloxrollers made out of glass or carbon fibre reinforced materials. On the other hand anilox roll manufacturers areconstantly looking for coating materials allowing finer engraved structures and the processing of higher inkvolumes at extended cleaning cycles.This paper describes basic trends in Flexoprinting and presents the development of a special carbide coatingsolution showing characteristic advantages compared to the standard plasma sprayed chromium oxide coating.Moreover the TeroStar?-process is being presented as a suitable high velocity spraying process to apply thiscarbide coating onto fibre-reinforced anilox rolls by fulfilling the quality requirements for the laser engravement.
