Abstract: Use of a rigid roller obtainable by a method comprising the steps: providing a roller core; applying a liquid coating composition based on a polyimide or polyamide-imide prepolymer with a layer thickness of 1 to 1000 ?m; solidifying the liquid coating composition on the roller core; as an distributor or Rilsan roller.

Abstract: A rubber-coated ink transfer roll having a hardness range of from 20 to 80 Shore A and a mean depth of roughness Rz of from 30 to 80 ?m and a maximum depth of roughness Rmax of from 40 to 120 ?m, a free specific volume V1 from 0.001 to 0.1 mm3/mm2 and a free specific volume V2 from 0.02 to 1.5 mm3/mm2.

Abstract: A film roller for offset printing having a surface with projections and recesses, characterized in that said projections and recesses form an irregular random pattern.

Abstract: Roll in a dampening system, particularly a dampening contact roll or dampening transfer roll or dampening ductor, comprising a core and an outer layer, wherein the outer layer is selected from the group consisting of hard anodized aluminum, chemical nickel and aluminum oxide, obtainable by plasmachemical anodic oxidation, and combinations thereof.

Abstract: Use of a sleeve for flexographic printing, comprising: a base sleeve; an intermediate layer enlarging the printing length, provided on the base sleeve and having a thickness of from 2 to 20 mm; a laser-engravable layer of a radiation-cured polymer; for enlarging the repeat.

Abstract: The present invention relates to an image carrier, for example, for use in electro-photography, containing at least one elastomer with cavities. The image carrier can be used, inter alia, in electrography, electrophotography (as a photoconductor) or magnetography and in color printing processes.

Abstract: A roller particularly suitable for applying varnishes onto sheet metal plates comprises a hollow roller core (10). The hollow roller core (10) is connected with pins (16,18) via coupling elements (20,22) arranged in the interior of the roller core (10). With respect to the front faces (26), the coupling elements (20,22) are arranged so as to be inwardly offset. Air exit openings are provided in a border region (28) of the roller core (10). A channel forming element (34) is provided to connect the air exit openings (32) with a roller interior (44). Through the channel forming element (34), a channel (36) is formed connected with the roller interior (44) via the opening (42) provided in the coupling element (20).
