摘要： A method of lithographic printing is disclosed which comprises the steps of unwinding a web of a flexible lithographic base from a supply spool, the lithographic base having a hydrophilic surface, wrapping the lithographic base around a cylinder of a printing press, applying on the lithographic base an 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 image-recording layer by supplying single-fluid ink, thereby obtaining a printing master, printing by supplying single-fluid ink to the printing master which is mounted on a plate cylinder of the printing press; and removing the printing master from the plate cylinder, preferably by winding up on an uptake spool. Since the image-recording layer can be processed by single-fluid ink, the imaging material is suitable for on-press processing in printing presses wherein no fountain solution is supplied to the plate. The method allows a rapid, fully automatic plate change with reduced press down time.

摘要： A method of making a lithographic image is disclosed, which comprises the steps of providing a lithographic imaging material comprising a support and a heat- or light-sensitive coating; image-wise exposure of the coating to heat or light, thereby obtaining a latent image in said coating, the latent image consisting of a set of exposed areas in the coating and a set of non-exposed areas in the coating; development of the latent image by supplying a processing liquid to the coating and evacuating, by means of a suction device, the processing liquid together with (i) substances removed from the exposed areas without removing such substances from the non-exposed areas or together with (ii) substances removed from the non-exposed areas without removing such substances from the exposed areas. The method is especially suitable for processing a lithographic printing plate while it is mounted in a plate-setter or a printing press, without the risk of damaging or contaminating electro-optical components of such equipment.
