Abstract: There is described coated on a lithographic base a complex of a developer-insoluble phenolic resin and a compound which forms a thermally frangible complex with the phenolic resin. This complex is less soluble in the developer solution than the uncomplexed phenolic resin. However when this complex is imagewise heated the complex breaks down so allowing the non-complexed phenolic resin to the dissolved in the developing solution. Thus the solubility differential between the heated areas of the phenolic resin and the unheated areas is increased when the phenolic resin is complexed. Preferably a laser-radiation absorbing material is also present on the lithographic base. A large number of compounds which form a thermally frangible complex with the phenolic resin have been located. Examples of such compounds are quinolinium compounds, benzothiazolium compounds, pyridinium compounds and imidazoline compounds.

Abstract translation: 描述了在平版印刷基底上涂覆显影剂不溶性酚醛树脂和与酚醛树脂形成热脆性复合物的化合物的复合物。 该复合物比未络合的酚醛树脂在显影剂溶液中的溶解性较差。 然而，当该复合物成像加热时，复合物分解，使得非络合的酚醛树脂溶解在显影溶液中。 因此，当酚醛树脂复合时，酚醛树脂的加热区域与未加热区域之间的溶解度差异增加。 优选地，激光辐射吸收材料也存在于光刻基底上。 已经定位了大量与酚醛树脂形成热脆性复合物的化合物。 这些化合物的实例是喹啉鎓化合物，苯并噻唑鎓化合物，吡啶鎓化合物和咪唑啉化合物。

Abstract: A lithographic printing plate that is transformable by spark-discharge techniques so as to change its affinity for ink. The plate features a layered structure including an ink-receptive substrate, a conductive layer and an ink-repellent coating. The ink-repellent coating contains a dispersion of crystalline metal oxide particles that promote straight-line travel of the spark to the surface of the plate, thereby promoting accurate imaging.

Abstract: An improved offset printing press (40, 120, 230, 132, 172, 202 and 212) has a single plate blanket image (PBI) cylinder (42, 124, 126, 134, 174, 176, 178, 204, 206, 214 and 232) for holding an image formed on a thin film printing plate (46, 138) affixed thereto. The plate (46, 138) may be from 0.5 to 10 microns thick and has a thin layer of ink repelling material (68) coated thereon. The plate (46, 138) is imaged, after being affixed to the PBI cylinder (42, 124, 126, 134, 174, 176, 178, 204, 206, 214 and 232), by ablating selective portions of the ink repelling coating (68). The PBI cylinder (42, 124, 126, 134, 174, 176, 178, 204, 206, 214 and 232) is constructed to hold the printing plate (46, 138) by vacuum. Apparatus (56, 57 and 198, 196) to load and unload the plate (46, 138) is associated with the PBI cylinder (42, 124, 126, 134, 174, 176, 178, 204, 206, 214 and 232). Because of the thinness of the printing plate (46, 138), the PBI cylinder (42, 124, 126, 134, 174, 176, 178, 204, 206, 214 and 232) is a compliant surface, capable of printing on an inelastic media covered impression cylinder (44, 136, 190, 216 and 234). Unique inking apparatus (54, 154, 156, 158, 160 and 188) is provided to transfer ink to the imaged printing plate (46, 138).
