    摘要: There is described a method of preparing a lithographic plate which comprises coating on a lithographic support having a hydrophilic surface a layer of a radiation sensitive coating, imaging the coating then acting on the plate while on the press with aqueous fount solution to remove the unexposed areas of the coating, to reveal the hydrophilic surface of the plate and to leave an ink receptive image, wherein the radiation sensitive coating comprises a diazo salt of formula (I): wherein R1 is an anion, R2 and R3 represent optional substitution, R4 is —N— and —S— and R5 is a group which, after exposure of the plate renders the residue of the diazo salt oleophilic and fount solution insoluble.

    摘要: There is described a method of preparing a lithographic plate which comprises coating on a lithographic support having a hydrophilic surface, a layer of a heat sensitive coating, digitally imaging the coating, then processing the plate with water to remove the unexposed areas of the coating to reveal the hydrophilic surface of the plate and to leave an ink receptive image, wherein the heat sensitive coating comprises a diazo salt of formula (I): wherein R1 is an anion, R2 and R3 represent optional substitution, R4 is —N— or —S— and R5 is a group which, after exposure of the plate, renders the residue of the diazo salt oleophilic and fount solution insoluble.

    摘要: A method of producing a resist pattern on a substrate using a precursor which comprises a coating composition which includes a heat sensitive polymeric substance having functional groups Q thereon (wherein groups Q may be siloxane or optionally substituted fluoroalkyl groups) wherein groups Q cause the polymeric substance to have a reduced adhesive interaction with ink for use in waterless lithographic printing compared to aid polymeric substance in the absence of said groups, the method including the step of causing the patternwise application of heat to said coating composition and optional development thereby to define ink accepting areas in heat exposed areas and non-ink accepting areas in non-exposed areas.

    摘要: A formulation comprising a heat sensitive cross-linkable ink and carbon black is coated over substantially the entirety of an ink-repellent/ink-releasing surface of a printing cylinder of a printing press by heating the formulation and/or the outer surface of the printing cylinder so that the formulation adheres to the cylinder to provide a continuous coating thereon. The coated printing cylinder is then allowed to cool to ambient temperature whereafter it can be imaged using a digitally controlled laser. The imaged printing cylinder may be developed during press start up by application of waterless ink over the cylindter surface in order to remove the non-imaged areas comprising non-cross-linked ink. After completion of printing, the printing cylinder can be cleaned by using an appropriate solvent to solubilize the cross-linked ink in the imaged areas and subsequently re-used.
