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: The invention relates to a method for repairing a printing roller having a roller base body made (10) of plastic or a plastic compound material. Into the two end regions (14) of the roller base body, bearing support members (16) are inserted, said bearing support members being connected to the roller base body (10) by bonding. Due to the occurrence of high stresses during the operation of the printing roller, inner surfaces (24) of the bearing support members (16) may be damaged. The damaged bearing support members (16) will be milled on their inner surfaces (24). Then, a respective sleeve (32,44) is inserted into the bearing support members (16). The inner surfaces (36) of the sleeves (32,44) serve for taking up outer bearing rings (26) of the roller bearings supporting the printing roller. The invention further relates to a printing roller with inserted sleeve (32,44).

Abstract: A printing blanket which resists gauge loss throughout its useful life when subjected to printing nip pressures by retaining at least 95% of its original gauge throughout the useful life of the printing blanket. The printing blanket includes at least a printing surface layer and at least one reinforcing woven fabric ply and may also include a compressible layer. At least one, and preferably all, of the reinforcing woven fabric plies in the blanket construction are treated or fabricated to resist permanent deformation when subjected to printing nip pressures.
