    Abstract: A process for producing an aluminum support for a lithographic printing plate is described, which comprises jetting a high-pressure liquid from at least one nozzle at a high rate, joining the jetted stream with a slurry containing a fine powder of an abrasive spouted from at least one spout, and directing the resulting mixed stream to strike against a surface of an aluminum plate to carry out cleaning and sandblasting at the same time.

    Abstract: A method of printing comprising applying a conductive developer to a imaged dielectric surface in the presence of an energising electrical image-defining field to form a master having conductive and relatively insulating areas defining the image, inking the said surface in the presence of a field of a polarity to urge the ink on to the surface to retain it at the relatively insulating image areas, and transferring the ink from the said surface to a receiving surface in the presence of a field of a polarity to urge the ink on to the receiving surface, and continuing inking the said master and transferring the ink to further receiving sheets.

    Abstract: A novel method of preparing a waterless lithographic master and a method of printing therefrom are provided. To prepare the printing master, a suitable substrate which can be photoconductive or non-photoconductive is imaged with a hydrophobic particulate image pattern and the image fused to the substrate. The imaged substrate is then coated with an aqueous silicone which does not wet the hydrophobic image pattern. The silicone is then heated to selectively provide ink-receptive image areas and ink-releasing non-image areas.

    Abstract: To delete undesired ink-receptive areas on a wet lithographic printing construction, an oleophobic material is applied to the hydrophilic surface of the plate that has suffered contamination and/or scratching, and allowed to cure. So long as the hydrophilic surface is capable of permanently bonding the oleophobic deletion agent, the areas to which that agent has been applied will not accept ink.
