Abstract

Disclosed is a surface treated doctor blade in which the surface of at least the blade edge portion thereof consists of a surface treatment coating film composed of a first layer consisting of a specific nickel-based plating and a second layer provided thereon which has low surface energy, and in which preferably at least a part of the blade edge end portion of the blade base material is exposed. In the surface treated doctor blade of the present invention, it is possible to improve wear resistance of the blade edge end and to suppress generation of printing failures during continuous printing. Further, in the mode in which at least a part of the blade base material is exposed, it is possible to reduce running-in time for adjustment of contact of the blade edge with the cylinder after replacement of the doctor blade.
