    摘要: A method for making a negative-working heat-sensitive lithographic printing plate precursor includes the steps pf: (i) providing a support having a hydrophilic surface or which is provided with a hydrophilic layer; and (ii) applying on the support a coating which includes a product DQ, wherein DQ is obtained by: the step of coating a solution or dispersion including a nucleophilic compound Q and a dye D selected from the list consisting of di- or tri-arylmethane dyes, cyanine dyes, styryl dyes, and merostyryl dyes; or by D and Q interact to form interaction product DQ, having a white light optical density which is lower that the white light optical density of dye D; and the interaction product DQ is capable of at least partially releasing a dye directly after exposure to infrared light or heat, therby forming a visible image in the coating.

    摘要: A method for making a lithographic printing plate includes the steps of providing a heat-sensitive lithographic printing plate precursor including on a support having a hydrophilic surface or which is provided with a hydrophilic layer, a heat-sensitive coating; image-wise exposing the precursor with IR-radiation or heat; and developing the image-wise exposed precursor with an alkaline developing solution, wherein an anti-sludge agent is present in the precursor or in the developing solution or in the precursor and the developing solution, and wherein the anti-sludge agent is a 5-membered heteroaromatic compound, including a —NH— group wherein the hydrogen is capable of being deprotonated in the alkaline developing solution, selected from the group consisting of an optionally substituted benztriazole, 1,2,3-triazole, tetrazole, or indazole compound. According to the above method, the formation of sludge is inhibited or reduced.

    摘要: A method for the preparation of a negative working lithographic printing plate by means of ink jet printing is disclosed. This method uses a lithographic printing plate precursor comprising a lithographic support and an image forming layer containing a polymeric binder soluble in an aqueous alkaline developer. The precursor is image-wise printed by an ink jet fluid comprising a compound capable of reducing the solubility of the binder in the aqueous alkaline developer. After development a negative working printing plate is obtained.

    摘要: A method for the preparation of a negative working lithographic printing plate is disclosed. A printing plate precursor comprising a lithographic support and an image forming layer is mounted on a printing press. A liquid containing a dissolution inhibitor is image-wise dispensed on the precursor by means of ink jet printing. The precursor is developed on press by the application of fountain and ink whereby the image areas are retained and the non-image areas are removed.
