Method for producing anilox rolls

The invention relates to anilox rolls for anilox color decks, engraved by a short-pulse laser, wherein the cross-sectional shape of the engraved cells or hachures is machined out by a plurality of pulses of the repeatedly operating laser. The pulse energy and mean power of the laser are selected or...

Beschreibung
Zusammenfassung:	The invention relates to anilox rolls for anilox color decks, engraved by a short-pulse laser, wherein the cross-sectional shape of the engraved cells or hachures is machined out by a plurality of pulses of the repeatedly operating laser. The pulse energy and mean power of the laser are selected or set so that at least 0.5 cm3 of material/hour is ablated. The surface of the roll is subsequently smoothed or cleaned by a mechanical finishing step.
