Abstract
The invention relates to a process for the production of structured retaining areas on sheet grippers, sheet gripper supports or similar gripper facilities for machines for handling and processing sheets by the formation of a non-etchable dot structure on the base member and the subsequent etching out of intervening areas. To provide structured retaining areas having a smoothly shaped surface, the dot structure is produced by screen printing or pressure pad printing and after the etching-out of unprinted areas, a hard smoothing coating, preferably of chromium or ceramic, is applied to the structural retaining area.
