  • Patent number: 6890688
    Abstract: This invention relates to a lithographic template, a method of forming the lithographic template and a method for forming devices with the lithographic template. The lithographic template (10, 110, 210) is formed having a substrate (12, 112, 212) and a charge dissipation layer (20, 120, 220), and a patterned imageable relief layer, (16, 116, 216) formed on a surface (14, 114, 214) of the substrate (10, 110, 210) using radiation. The template (10, 110, 210) is used in the fabrication of a semiconductor device (344) for affecting a pattern in the device (344) by positioning (338) the template (10, 11, 210) in close proximity to semiconductor device (344) having a radiation sensitive material (334) formed thereon and applying a pressure (340) to cause the radiation sensitive material to flow into the relief image present on the template (10, 110, 210).

  • Patent number: 6866985
    Abstract: With the method according to the invention for producing a printing plate, in particular for flexoprinting, a layer of a curable elastomer is applied to a carrier (15) with a cylindrical surface area (26), subsequently the elastomer layer is cured to an essentially cylindrical endless printing form blank and possibly ground to a cylindrical peripheral form or processed otherwise, and afterwards the printing form blank (33) is separated along a line which is essentially parallel to the axial direction of the carrier and the printing plate produced in such a manner.

  • Patent number: 6851365
    Abstract: A method for producing multicolor printing, by using printing plates provided digitally with images and/or print, represents an efficient solution for multi-color printing, in particular in a large format. Printing plates, which had been used in a printing press, are removed from the printing form cylinders, are sent to a device for neutralization, and are neutralized. The neutralized printing plates are fixed at correct registration in an exposure and development unit where they are exposed and developed. The printing plates provided with new images are again applied to the printing form cylinder.

  • Patent number: 6851364
    Abstract: A printing plate material which can be adapted to digitization of the printing process and recycled and a method for renewing it. As the printing plate material, there can be used one which includes a substrate on the surface of which a coat layer containing a titanium oxide photocatalyst and at least one member selected from salts or oxides of Fe2+, Ni2+, Mn2+, Cr3+, and Cu2+ is formed. In an initial state of the printing plate as prepared, it is adjusted to a state where the surface of the coat layer is hydrophobic. This surface is irradiated with ultraviolet rays to convert a part of the surface to a hydrophilic surface. This conversion is performed based on digital data corresponding to an image to be printed. In this case, the hydrophobic portion is used as a printing image portion and the hydrophilic portion is used as a non-printing image portion.

  • Patent number: 6815139
    Abstract: A method of making a lithographic printing master is disclosed which comprises the steps of providing an imaging material which comprises a lithographic base having a hydrophilic surface and a non-ablative image-recording layer which is removable in a single-fluid ink or can be rendered removable in a single-fluid ink by exposure to heat or light; image-wise exposing the image-recording layer to heat or light; processing the material by supplying to the image-recording layer a single-fluid ink which is an emulsion of an ink phase and a non-aqueous polar phase. The use of single-fluid ink as processing liquid is a simple, convenient method for the on-press processing of the above defined material.

    Abstract: Plate positioning and processing method and apparatus are disclosed. A plate is conveyed in a predetermined first direction so that the plate is in contact with a pair of first positioning pins. The plate is laterally moved contacting with the first positioning pins until reference positions displaced from contacting positions of the plate with the first positioning pins contact with the first positioning pins. A predetermined first processing is applied to the plate. The plate subjected to the first processing is conveyed in a predetermined second direction so that the plate is in contact with a pair of second positioning pins in positions different from the reference positions of front edge of the plate. The plate contacting with the second positioning pins is laterally moved until the same positions as the reference positions contact with the second positioning pins.
