Abstract
To facilitate the manufacture of an anilox roller for an inker of an offset rotary printing machine, a cylindrical core has a layer of ink accepting material, for example copper, applied thereon. To form wear-resistant ribs (8) between which ink receptor depressions or cells (19) can be formed, the layer (3) of ink accepting material is formed with grooves into which a hard, wear-resistant material is applied, completely filling the grooves. The ink receptor depressions or cells are then formed in the ink accepting material, which is softer than said wear-resistant material. The thickness of the ink accepting layer (3) originally applied is greater than the depth of the cells which, typically, have a depth of about 0.02 mm.
