  • PRINT HEAD ELEMENT, PRINT HEAD AND IONOGRAPHIC PRINTING APPARATUS
    Publication number: 20130127969
    Abstract: A print head element part of an ionographic print head is provided having a mechanism for introducing at one end an ionisable gas or gas mixture into a tubular channel, the print head element further having a planar driver electrode and a planar control electrode both surrounding channel, a dielectric body keeping driver electrode and control electrode separate, a source for applying an alternating voltage for the ionization of the gas or gas mixture in channel, a modulation electrode being separated from control electrode by dielectric material, a source for applying a direct current voltage between modulation electrode and control electrode to either block ions in channel or to allow the flow out of ions from channel.

  • Drum-type imagesetter with variable diameter
    Patent number: 5839030
    Abstract: Drum-type imagesetter for producing an image on a flexible sheet of radiation-sensitive material, which comprises retaining bars (62) for retaining a sheet in a substantially cylindrical configuration, and an exposure system (70) for image-wise exposing the curved sheet, the radial position of the sheet retaining bars (62) being controlled by adjustment screws (49, 50) allowing different drum diameters to be set.

  • Method and apparatus for making a lithographic offset plate by the silver salt diffusion transfer process
    Patent number: 5561027
    Abstract: A method and apparatus for making an offset printing plate according to the silver salt diffusion transfer process comprises the step of washing the imaging element by applying a curtain of an aqueous medium onto the surface of the element at its silver halide emulsion layer side, across the width of the element, substantially transverse to its processing direction, and in countercurrent to the processing direction of the element.
