ABSTRACT Inking roller and method for the production thereof. A method is described for producing an inking roller in the form of a screen roller for an offset inking mechanism or similar ink applicator, in which during the scraping process a doctor blade slides over the surface of the webs giving the screen system. To the roller cylinder is applied a metal and/or hard ceramic layer, in whose abras- ion-resistant, hydrophilic surface are engraved by a laser beam the said webs between the depression which are exposed. Hydrophobic lining material covers the walls of the depressions in an at least partial manner. Initially the depressions are substantially completely filled with hydrophobic lining material, which is subseque- ntiy removed until the webs are exposed and then into the lining material of the filled depressions is formed a plurality of cells for receiving the ink or the line and whose arrangement and structure are independent of the depressions.
