    Abstract: A system and method are provided for depositing a release layer/film on a cleaner roller in an image forming device to facilitate effective cleaning of a reimageable surface in an image forming device using a proposed variable data digital lithographic image forming architecture. A borax or other solute solution is deposited on a surface of a cleaner roller and an air knife is used to evaporate a liquid component of the solution causing the liquid to come off and a thin-film of borax or other solute to remain on the surface of the cleaner roller. The thin film layer is then dry at a point of contact with the reimageable surface to recover residual ink from the reimageable surface with the surface of the cleaner roller on top of the thin film layer. The thin film layer is re-wetted to support efficient transfer of the ink to a web.

  • Patent number: 8981254
    Abstract: In a method for re-imaging a printing form that has been used for printing in a prior printing process a substrate of the printing form is cleaned globally of ink or varnish and the substrate is treated abrasively globally in order to erase a preceding printing image. The substrate to be imaged with a new printing image is treated locally in image regions with a pulsed laser beam and, in the process, a nanoscopic and hydrophobic surface structure is produced locally. The substrate is treated globally with a hydrophilicity intensifier, as a result of which the substrate becomes hydrophilic locally in the previously hydrophobic image regions. An apparatus has a corresponding erasing unit and an imaging unit with a femtosecond laser.

  • Publication number: 20090020031
    Abstract: An apparatus and method for treating a rotating printing technology surface, especially a re-imageable printing form, with a process liquid, such as cleaning, covering or rinsing liquid, include jet nozzles disposed along a straight line substantially parallel to the axis of rotation of the printing technology surface, and a cloth device substantially parallel to the axis of rotation. The nozzles pivot about a pivot axis substantially perpendicular to the axis of rotation for producing a substantially uniform distribution of process liquid parallel to the axis of rotation. The cloth device preferably has a cloth with segmented or calendered portions substantially parallel to the axis of rotation, for substantially limiting spread of process liquid in the cloth parallel to the feed direction of the cloth and assisting substantially uniform distribution of process liquid parallel to the axis of rotation. Machines for processing printing material and for treating printing forms are also provided.

  • Patent number: 7434510
    Abstract: A cleaning method for the screen stencil of a silk-screen printing machine. According to the method, prior to an intermediate printing process designed to clean the screen stencil, the underside of the stencil is wetted with a cleaning agent that dissolves dye. An intermediate printing device includes an intermediate printing roll that can be displaced back and forth. A rotating roll that is immersed in a cleaning bath is situated at the front end of the intermediate printing roll. The rotating roll can be brought into contact with the underside of the screen stencil prior to the intermediate printing process by means of a pivoting device.
