A doctor blade () for contact with an anilox roller () comprises a flat, elongate base element having a thickness of less than about 0.3 mm, which, along a longitudinal region of the doctor blade adapted for contact with said anilox roller, is provided with a coating (). The coating comprises a metal matrix and at least about 65% by weight of one or more ceramic(s). The coating comprises 0 to 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.

In a general aspect, a coating blade for application of coating color to a fibrous web can include an elongate substrate having a longitudinal edge. Within an operating zone of the coating blade intended for contact with a coating color, the elongate substrate can include a longitudinal wear-resistant deposit adjacent to the longitudinal edge. The coating blade, within the operating zone, can also include a longitudinal masking deposit adjoining the longitudinal wear-resistant deposit.

A blade for creping a paper web from a dryer surface is provided, said blade having a sliding surface facing the dryer surface during use of the blade, a web impact surface upon which the paper web impacts during creping, and a working apex formed between the sliding surface and the web impact surface, wherein the working apex is located no more than 30 percent of the total blade thickness away from a neutral fiber of the blade. Preferably, the working apex of the inventive creping blade is located at or close to the neutral fiber of the blade. A method for manufacturing the blade is also disclosed.
