摘要： A reimageable printing member such as a printing plate for use in flexography, includes a layer having a multiplicity of channels therein. The layer has an open side to which the multiplicity of channels are open. The reimageable printing member further includes a filed generator such as an electrode or a magnetic field generator associated with the multiplicity of channels and generating an electric and/or magnetic field. The multiplicity of channels are individually addressable, thereby permitting the field to be applied to selected ones of the multiplicity of channels so that the marking material within such selected channels can be manipulated to move out of the channel and onto an image receiving substrate brought into contact with the open side of the layer, thereby forming an image on the substrate.

摘要： A method is presented for preparing a lithographic printing plate by an ink jet process of discharging dropwise an oil-based ink using electrostatic attraction onto a lithographic printing plate precursor to form an image. The lithographic printing plate precursor has a water-resistant support having provided thereon an image-receiving layer having a lithographically printable hydrophilic surface for forming the image. The water-resistant support has a specific electric resistance of 10.sup.10 .OMEGA.cm or less in an area directly under the image-receiving layer. The oil-based ink is composed of positively or negatively charged electroscopic resin particles dispersed in a nonaqueous carrier liquid having an electric resistance of 10.sup.9 .OMEGA.cm or more and a dielectric constant of 3.5 or less. The resin particles are copolymer resin particles obtained by polymerization granulation of a solution of a monofunctional monomer, a monofunctional macromonomer and a resin for dispersion stabilization.

摘要： A process for the production of a colored image by an electrophotographic route by electrostatic charging, imagewise exposure to light and toning of a photoconductor material with a colorless transparent toner which includes a colorless polymeric binder and a colorless polymeric charge control agent, and transfer of the toner image to a colored layer which is soluble in a solvent and is on a layer carrier, fixing of the toner image and removal of the areas of the colored layer not covered by the toner image by washing out with a solvent. The process utilizes the high photosensitivity of electrophotographic materials, without the possibility of color falsification due to colored toners. The procedure is simpler compared with known electrophotographic processes, since the same toner can be employed in all steps and does not have to be washed off.
