Abstract
Doctor blades (5, 7) for contact with an anilox roller (15) comprise a flat, elongate base element, which, along a longitudinal region of the doctor blade adapted for contact with said anilox roller, is provided with a coating (43). The coating comprises a metal matrix and at least about 65% by weight of a ceramic or at least about 65% by weight of chromium carbide. An inking arrangement comprises an anilox roller and a doctor blade. A doctor blade is used in flexographic printing.
