摘要： A lithographic printing method is disclosed which comprising the steps of providing an imaging material which comprises a support and an image-recording layer that is not removable with a single-fluid ink which comprises an ink phase and a polar phase; image-wise exposure of the image-recording layer to heat or light without substantially ablating said image-recording layer, thereby switching the affinity of the image-recording towards ink or an ink-abhesive fluid and thereby creating a printing master comprising a lithographic image which consists of unexposed areas that have affinity for one phase of said ink phase and polar phase and of exposed areas that have affinity for the other phase of said ink phase and polar phase; printing, wherein the single-fluid ink is supplied to the printing master. The exposed image-recording layer, which normally exhibits a poor differentiation of hydrophilicity or oleophilicity between exposed and non-exposed areas, provides high quality printed copies in combination with the single-fluid ink.

摘要： A lithographic printing plate precursor comprises a grained and anodized aluminum substrate coated with a metallic layer, preferably a silver layer, on top of which is applied a layer comprising at least one oleophilising agent and at least one hydrophilic stain-reducing agent, the hydrophilic agent being chosen such that it adsorbs onto the metallic layer but is not so strongly adsorbed thereon as to displace the oleophilising agent. Preferably, the oleophilising agent comprises a mercaptotetrazole or mercaptooxadiazole derivative, the hydrophilic stain-reducing agent comprises a material which includes at least one sulfur, selenium or tellurium containing group, and the layer additionally comprises an additional hydrophilic material. The invention provides lithographic printing plate precursors which may be image-wise exposed by means of a high intensity laser beam to provide press ready plates showing reduced stain in non-image areas, high image quality, good press properties and high durability on press without the requirement for the use of intermediate film and developer chemistry.

摘要： An off-press plate-making apparatus is provided which comprises means for removing the lithographic image from the substrate of a used printing master and means for recoating the recycled substrate with a new image-recording layer. The off-press cleaning and recoating of the substrate provides a short press down-time. The recoated substrate forms an imaging material which can be exposed either on-press in a digital press comprising an integrated exposure apparatus or off-press in an exposure apparatus, which can be integrated in the plate-making apparatus or mechanically coupled thereto.

摘要： A direct-to-plate method of lithographic printing is disclosed wherein a printing press is used that is coupled to a coating apparatus and to a cleaning apparatus; wherein the coating apparatus applies an image-recording layer on a substrate so as to obtain a printing plate, which is mechanically transferred to the printing press; and wherein, after the print job, the printing plate is mechanically transferred to the cleaning apparatus wherein the substrate is recycled, so that the recycled substrated can be reused in a next cycle of coating, printing and cleaning. The off-press coating and the off-press cleaning step provide a fully automated printing method wherein the press down-time is minimized. The method comprises also an off-press or an on-press exposure step.
