Abstract: A printed product is produced by applying at least one colored and water-containing ink to image regions on a printing material in a drop-on-demand process, applying a substantially colorless and water-containing liquid a) to non-image regions and/or b) to image regions that have little ink in a drop-on-demand process and drying the printing material. In this case, the printing material has a coating with at least one acid. After applying ink and applying the liquid, a water-containing further liquid is applied both to image regions and to non-image regions of the printing material. The first-mentioned liquid and/or the further liquid contains at least one substance for at least partly neutralizing the acid. The undesired formation of crease waves or curls and glossiness fluctuations between varnished image areas and varnished non-image areas is thus advantageously avoided.

Abstract: A method for configuring the further processing of printing substrates in a digital printing machine includes modifying settings for configuring the further processing while the machine is in operation. The settings of the further processing are created by using a configuration program running on a control unit of the digital printing machine. The modified settings have an effect on at least one region to be further processed on the printing substrate and the settings are printed onto the printing substrate so as to be allocated to a corresponding region to be further processed.

Abstract: A method for operating a cleaning apparatus, having a trough and a brush disposed in the trough, in a printing press, includes first, second and third steps. In the first step, a cylinder of the printing press is cleaned by the cleaning apparatus, with the brush bearing against the cylinder. In the second step, the brush is moved away from the cylinder, and a level of a liquid in the trough is changed, resulting in the liquid being brought into contact with the brush. In the third step, the brush is cleaned by the liquid in the trough. A printing press for carrying out the method is also provided.

Abstract: Example embodiments relate to a server for providing remote storage space to users. The server may include a mechanism that allocates a portion of storage space in the storage area in response to a request from a first remote user. The server may also include a mechanism that maintains storage records, the storage records identifying a user currently granted exclusive access to the portion of storage space. Furthermore, the server may include a mechanism that processes access requests to determine whether a remote user requesting access to the portion of storage space is the user currently granted exclusive access. Related clients, methods, and machine-readable storage media are also disclosed.

Abstract: Embodiments disclosed herein relate to conducting surveillance using a digital picture frame. A digital picture frame may comprise a sensor and a storage medium. The digital picture frame may receive surveillance information from the sensor and store the surveillance information in the storage medium. A second electronic device may receive the surveillance information from the digital picture frame via a network.

Abstract: An apparatus for driving a roller of a printing press includes a main motor configured to drive the roller through a first gear wheel and a first freewheel, and an auxiliary motor configured to drive the roller through a second gear wheel and a second freewheel. A brake that is different from the main motor, for example a band brake, is configured to brake the roller during overrunning of the roller following a machine stop signal. A printing press having the apparatus is also provided.

Abstract: A method for operating a printing press having a printing unit and a cleaning apparatus includes, in a first step, starting up the printing unit in order to print therewith, and in a subsequent, second step, displacing the cleaning apparatus into the printing unit running in printing operation and/or out of the printing unit running in printing operation. A printing press for implementing the method is also provided.

Abstract: A printing press includes a form cylinder, a blanket cylinder, an impression cylinder, an adjusting apparatus having at least one first actuating drive for setting a printing pressure between the blanket cylinder and the impression cylinder, and a tracking system for setting a printing pressure between the form cylinder and the blanket cylinder in dependence on the setting of the printing pressure between the blanket cylinder and the impression cylinder. The tracking system has at least one second actuating drive coupled to the at least one first actuating drive in terms of control technology through an electronic control device, in such a way that the form cylinder is adjusted automatically.

Abstract: A printing press has a printing unit with a cylinder and a cleaning device that is mounted for selective displacement into an operating position for cleaning the cylinder and into a maintenance position away from the cylinder. The operating position is located within the printing unit and the maintenance position, although being located outside the printing unit, is located on the press. While the press runs in printing operation, the cleaning device is kept away from the operating position.
