  • Patent number: 10124576
    Abstract: A cleaning apparatus includes an inker roller and an ink source holding ink for the inker roller. The inker roller contacts a reimageable surface of an imaging member downstream of an ink image transfer station that transfers an ink image from the surface to a print sheet, with the surface having residual ink remaining thereon after the transfer of the ink image. The inker roller applies ink from the ink source against the reimageable surface. However, instead of the ink transferring from the inker roller to the surface, the ink stays with the inker roller and removes the residual ink from the surface to clean the surface for a subsequent ink image. The inker roller is not contaminated from removing the residual ink as the inker roller is designed to be coated by ink that adds to its coating of ink via the removed residual ink.

    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.

  • Publication number: 20140290515
    Abstract: An extractor for placement adjacent to a rotor having processing positions in a circumferential area thereof extracts contaminants arising during container processing. The extractor has a hood forming an interior, an extractor channel, baffles, flow channels, and a joint suction channel. In operation, the hood, which does not move with the rotor, extends over part of the circumferential area. The hood's interior opens radially towards the rotor and is connected by the extractor channel to a suction device. The baffles, which are formed by wall elements in the hood interior, define the flow channels. The flow channels are open on a side of the hood that faces the rotor, and open inside the extractor hood into the joint suction channel.

  • Patent number: 8827410
    Abstract: A method of cleaning a heated drum within a continuous web printer includes operating an actuator to rotate a drum that is heated to a first temperature. The drum rotates in a process direction of a media web contacting the drum and heats the media web as the media web moves over a portion of the drum. The method also includes stopping movement of the media web, heating the drum to a second temperature that is greater than the first temperature, and operating the actuator to rotate the drum against a portion of the stopped media web to transfer ink from the drum to the portion of the stopped media web.

  • Patent number: 8800440
    Abstract: It is an objective to provide a screen print system and a method for cleaning a mask of the screen print system that enable sufficient cleaning of the mask used for subjecting a cavity substrate to screen printing. A mask contact area R of a paper member 42 is brought into contact with a lower surface of one of convex portions 13t of a first mask 13a, thereby removing paste Pst adhering to the lower surface. Subsequently, the paper member 42 is winded up before the paper member 42 contacts the next convex portion 13t to be subjected to removal of the paste Pst, thereby updating the mask contact area R.
