The method includes providing a receptor element having an image-receiving layer capable of receiving a first chemical agent in areas corresponding to the blocked areas of the stencil to be produced. A first chemical agent is applied to the image-receiving layer of the receptor element in the corresponding areas. A second, stencil-forming chemical agent is then applied to a screen printing screen and the image-receiving layer fo the receptor element brought into contact with the stencil-forming agent to allow the first and second chemical agents to react to produce on the screen a stencil-forming layer having areas of lower solubility corresponding to the said blocked areas and areas of higher solubility in areas corresponding to the open stencil areas.

  • Patent number: 6679166
    Abstract: In a method and apparatus for perforating a heat sensitive stencil sheet having a heat shrinkable film, the film is selectively heated with a heating device to form independent dot perforations corresponding to an image, and the heating device is controlled to ensure that the perforations satisfy the following formula (1): p≧d+({square root over ( )}2)f  (1) where p denotes a scanning pitch in a main scanning direction or a sub scanning direction; d denotes an inner diameter of a perforation in the same direction as p; and f denotes a width of a rim of said perforation at a portion that is not merged with any rims of its adjacent perforations. Irregularity of perforation configuration is decreased, size of perforations is kept adequate, and the heating device does not have to be heated to a high temperature.

  • Patent number: 6679167
    Abstract: An image display medium 1 includes a film body 2 having a number of microscopic film pieces 2a. The film body 2 is sandwiched between a supporting member 3 having receiving spaces 5 and a cover member 4. The image display medium 1 is brought into contact with a rotary drum 26 of an image generating apparatus. Corresponding to a perforated image in a stencil sheet 101 attached to the rotary drum 26, the respective microscopic film pieces 2a of the film body 2 are selectively absorbed to the cover member 4 or partitions 5a of the supporting member 3.

  • Patent number: 6675705
    Abstract: A microporous stencil sheet for use in stencil printing and methods for making stencil master using this microporous stencil sheet are disclosed herein. The microporous stencil sheet is for use in stencil printing using a low-viscosity ink with a viscosity ranging from 0.001 to 1 Pa·s, comprises an inelastic resin film and has an air permeability ranging from 1 to 600 seconds and a thickness ranging from 1 to 100 &mgr;m. The methods for making stencil master using this microporous stencil sheet comprise the step of closing the micropores of the stencil sheet in a non-printing portion of a desired printed image.

  • Patent number: 6659003
    Abstract: A perforation pattern is provided with a stencil plate, which is decreased in perforation configuration irregularity and has an adequate size of perforations. The stencil plate is produced from a heat sensitive stencil sheet having a heat shrinkable film by selectively heating the film with a heating device to form independent dot perforations corresponding to an image in the film, and each of the perforations has a through hole and a rim surrounding the through hole and bulging on a heated side of the film, and the rim has a height that satisfies the following formulae (1) and (2): h≦4 (&mgr;m)  (1) h≦0.05{square root over ( )}(pxpy)(&mgr;m)  (2) where h denotes the height (&mgr;m) in reference to the surface of the film before heated, px and py respectively denote pitches (&mgr;m) in main and sub scanning directions of the heating device.

  • Patent number: 6634288
    Abstract: A stamp member 11 includes a porous resin 101 and a film 103 adhered together by an acrylic adhesive 102. The film 103 is peeled from the porous resin 101 after stamp making operations have been completed for forming a stamp image on a stamp surface 71 of the porous resin 101. Therefore, the stamp surface 71 of the porous resin 101 is protected from fine dirt and dust. Also, because there is no need to proved a film between a stamp making device and the stamp member 11 at stamp making operations, stamp making operations are simplified.

  • Patent number: 6572951
    Abstract: A printing sheet which prevents setoff while transferring a sufficient quantity of ink and maintains necessary dot uniformity can be obtained by ensuring characteristics that the centerline average roughness showing the larger value is 1.0-3.5 &mgr;m and the ratio of centerline average obtained by dividing the larger value by the smaller value is less than 1.15 where said values are chosen at the point where the difference between the centerline average roughness in a certain direction and the centerline average roughness at right angles to said direction is maximal. Further, the abovementioned quality is further improved by appropriately ensuring that the oil absorbability is more than 4 mg/cm2 and less than 7 mg/cm2 when the contact time between the oil component having a surface tension of 27-30 mN/m at 20° C. and the printing sheet is 5 seconds and/or that the median pore diameter is 1.7-3.5 &mgr;m, in addition to the abovementioned characteristics.
