    Abstract: A system comprises an electrophotographic subsystem, a transfer subsystem, an imaging member, and an inking subsystem. The electrophotographic subsystem comprises a photoreceptor, a charging subsystem, an exposure subsystem, and a development subsystem. In operation, the photoreceptor is charged areawise. An exposure pattern is formed by the exposure subsystem on the surface of the charged photoreceptor to thereby write a latent charge image onto the photoreceptor surface. The image is developed with an image definition material, such as a dampening fluid. The image definition material forms a positive pattern of the image to be printed. The image pattern is then transferred to the reimageable surface. The transferred pattern is then developed by selectively applying an ink over regions of image definition material. The inked image may be transferred to a substrate.

  • Patent number: 7963220
    Abstract: A stencil printing apparatus in which the generation of discharge sheet peeling problems and defects such as creasing and tear of the stencil base sheet can be prevented while printing on a coated sheet. When a printing sheet set in a sheet-feed device is indicated by input via a sheet-type input device as a coated sheet, or when a printing sheet set in a sheet-feed device is automatically detected by a sheet-type detection device as a coated sheet, a control device judges on the basis of a detected signal from the base-sheet type detection device whether or not the stencil base sheet type set in the platemaking apparatus is for coated sheet printing, and permits platemaking start if the stencil base sheet is for coated sheet printing and issues a warning without permitting platemaking start if the stencil base sheet is for non-coated sheet printing.

  • Patent number: 7891292
    Abstract: A printing method and a printing apparatus including a stencil printing apparatus and so on. Focusing on the relationship that exists between copy number and master position displacement that occurs during printing, by determining by pretest and setting top-bottom shift correction values in accordance with parameters including copy number that affect printed master position displacement in the direction of rotation of a plate cylinder, and during printing, utilizing conventionally used top-bottom shift means to automatically execute top-bottom shift correction in accordance with the set top-bottom shift correction values, printing position displacement can be prevented from occurring, waste of master and printing medium such as paper can be eliminated and, in addition, the operation time can be shortened and the number of operation steps can be reduced.

  • Patent number: 7882781
    Abstract: A duplex printing apparatus capable of printing by performing a slow-up operation on the printing speed so that it increases from a low speed to a set speed at the time of duplex printing. Control means controls, on the basis of a drum rotation position signal and a drum speed signal from a home position sensor and an unshown encoder sensor, a sheet feeding unit, printing unit, sheet discharge unit, sheet re-feeding means and switching member, such that the printing speed (drum speed) slows up from a low speed to a set speed in each rotation of a plate cylinder, which corresponds to feeding of each sheet to the printing unit when duplex printing is started, and further controls a stepping motor of the sheet re-feeding means such that conveyance speed of a sheet receiving board synchronizes with the printing speed.

  • Patent number: 7849793
    Abstract: A double-sided printing apparatus using a double sided printing with one plate cylinder and one pressing means system, that is capable of carrying out double-sided printing simply and at low cost, with little deviation in the position of the printed image and with satisfactory resist. Printed matter with little deviation of the image position with respect to the sheet position and with good resist can be obtained, by eliminating delay in feeding sheets due to slippage between roller and press roller by operating the transport belt on the upstream side, and so on, and by eliminating resistance during sheet transportation due to contact with the guide member provided along the circumferential surface of the press roller, when pressing sheets against the press roller with a roller or the like, and transporting the sheets along the guide member or the like provided along the peripheral surface of the press roller.
