摘要： The invention provides a lithographic printing plate precursor comprising a grained and anodized aluminium substrate having coated thereon a silver halide emulsion layer, the back surface of said substrate being coated with an inert coating which does not chemically or physically interact with an adjacent silver halide layer when two plates are placed in front to back contact. Fogging of the silver halide layer is avoided and the use of the back coating eliminates the requirement for the use of tissue interleaving when wrapping and packing the lithographic printing plate precursors.

摘要： The present invention provides a method of preparing a lithographic printing plate, said method comprising: providing a lithographic printing plate precursor comprising: i) a grained and anodized aluminum substrate where the anodic weight is between 6.0 and 20 g/m2, having coated thereon; ii) a metallic layer; and image-wise exposing the precursor on an external drum thermal imaging device. The method provides press ready plates showing high image quality, good press properties and high durability on press without the requirement for the use of costly intermediate film and developer chemistry, and the attendant inconvenience resulting from the use of these materials.

摘要： An apparatus is provided for processing a lithographic printing plate precursor comprising an aluminium support, an image-receiving layer and a silver halide emulsion layer. The apparatus comprises a tank for holding a processing liquid, at least one set of driving rollers, at least one guide roller or guide plate and means for providing direct electrical contact between the lithographic printing plate precursor and other electrically conducting surfaces in the apparatus which are in contact with the processing liquid. A method of processing a lithographic printing plate precursor using the apparatus is also disclosed. Undesirable electrochemical cell formation during processing, and the consequent deleterious effects on silver image formation, are prevented and subsequent problems with poor plate run length can therefore be avoided.
摘要翻译：提供了一种用于处理包含铝载体，图像接收层和卤化银乳剂层的平版印刷版原版的设备。该设备包括用于保持处理液体的容器，至少一组驱动辊，至少一个引导辊或引导板和用于在平版印刷版前体与设备中的其它导电表面之间提供直接电接触的装置，与处理液接触。还公开了使用该装置处理平版印刷版原版的方法。在处理期间不希望的电化学电池形成以及随之而来的对银图像形成的有害影响被防止，因此可以避免随后出现的板长度差的问题。
