In the process for partially shaping, a glass/glass ceramic article () is held on a planar support plate () by suction. The glass/glass ceramic article is heated to soften it, so that it has a viscosity below 10dPa&#xb7;s. After the softening one or more shaping dies () is or are moved upward through an opening or respective openings () in the support plate to form raised regions in the softened glass/glass ceramic article (). The suction force is produced by a low pressure in a hollow compartment () below the support plate () and acts on the glass/glass ceramic article () by means of a gap (G) formed between each shaping die () and the support plate. Additional openings can be provided in the support plate and/or in one or more of the shaping dies to assist in applying the suction force to the glass/glass ceramic article. After solidification of the softened glass/glass-ceramic article the shaping die or dies () is or are withdrawn. Then the partially shaped glass/glass ceramic product is removed by compressed air and/or mechanically with lifting members (). An apparatus for performing this process is also described.

A printing machine with an electrophotographic device, having a photoconductor, a photoconductor drive and an illumination device. The electrophotographic unit can be provided with the substrate by a feed device. The photoconductor drive motor is adjusted by a controller and the feed device can be linearly adjusted by a feed device drive motor. In order to produce high-definition prints, especially images or lettering on plate-shaped substrates, the feed device drive motor is adjusted by a controller that is controlled by a master-slave controller via a setpoint feed. The controller for the photoconductor drive motor is also controlled by the master-slave controller via a setpoint feed and the master slave controller synchronizes the feeding speed of the feed device and the speed of movement of the photoconductor.
