摘要： Disclosed is an environment friendly waterless offset plate. The waterless offset plate is formed by: coating a base coating on a surface of a metal plate substrate not subject to electrolytic graining and/or anodic oxidation treatment but subject to oil-removal solution immersion, coating a diazonaphthoquinone light-sensitive adhesive layer on a surface of the base coating, coating an ink-repulsive layer on a surface of the diazonaphthoquinone light-sensitive adhesive layer, and further covering a polymer protective film on a surface of the ink-repulsive layer. The waterless offset plate has a good printability, and has a pressrun up to 10 to 30 thousand copies.

摘要： On-press developable, negative-working lithographic printing plate precursors have a sulfuric acid anodized aluminum-containing substrate in which the oxide layer pores have been widened using an acidic or alkaline treatment. Over the widened pores, a hydrophilic coating is applied, which coating comprises a non-crosslinked hydrophilic polymer having carboxylic acid side chains. This particular substrate provides improved adhesion and printing durability for on-press development and printing.

摘要： Embodiments of the present invention involve printing members that utilize a particle-fusion imaging mechanism but avoid susceptibility to handling damage. In particular, printing plates in accordance with the invention may utilize two phases, and these may originate, during manufacture, as two particle systems. Both systems are initially dispersed in a single coating applied as a layer, or in multiple coatings applied as adjacent layers, on a substrate. The second particle system exhibits a glass-transition or thermal coalescing temperature well above room temperature and also above the temperature at which the coating is dried. The coalescing temperature of the first particle system is below the drying temperature. As a result, when the coating is dried, the first particle system coalesces and forms a binder that entrains the second particle system, which has not coalesced. The binder formed by the first particle system is preferably insoluble in aqueous liquids, but is swellable or softened by such liquids, whereas the binder formed by the second particle system is preferably insoluble in and not swellable by aqueous liquids. Aqueous insolubility allows the dried (and ready-to-image) coating to resist handling damage, while swellability facilitates development.
摘要翻译：本发明的实施例涉及使用粒子 - 融合成像机构的打印构件，但是避免了对处理损伤的敏感性。特别地，根据本发明的印版可以利用两个阶段，并且这些可以在制造期间作为两个粒子系统产生。两种体系最初分散在单层涂层中，作为一层施加，或者在作为相邻层施加的多层涂层中分散在基底上。第二颗粒体系表现出远高于室温的玻璃化转变或热聚结温度，并且还高于涂层干燥的温度。第一颗粒系统的聚结温度低于干燥温度。结果，当涂层干燥时，第一颗粒系统聚结并形成夹带未结合的第二颗粒体系的粘合剂。由第一粒子系统形成的粘合剂优选不溶于水性液体，但是由这种液体可膨胀或软化，而由第二粒子体系形成的粘合剂优选不溶于水性液体并且不能溶胀。水不溶性允许干燥（和准备成像）涂层抵抗处理损伤，而溶胀性促进了发展。

摘要： A method for making a lithographic printing plate precursor is disclosed comprising the steps of a. providing a lithographic printing plate precursor including a support having a hydrophilic surface or which is provided with a hydrophilic layer, a photopolymerizable coating comprising a photopolymerizable composition, and an overcoat layer comprising a water soluble low molecular weight acid, wherein said overcoat layer has a surface pH-value ranging between 1 to 6; b. image-wise exposing the precursor; c. optionally heating the exposed precursor; d. processing the obtained precursor by applying a gum solution and optionally brushing the precursor, and/or by mounting the precursor on a plate cylinder of a lithographic printing press and rotating the plate cylinder while feeding dampening liquid and/or ink to the coating. The printing plate obtained after imaging and processing in an off-press configuration with a gum solution or in an on-press configuration with fountain solution and ink shows an improved roll-up performance in the start-up of a printing process on a printing press.

摘要： A lithographic printing plate precursor comprises an imageable layer comprising a free radically polymerizable component, an initiator composition capable of generating free radicals upon exposure to imaging infrared radiation, an infrared radiation absorbing dye that is defined by Structure (I) shown in the disclosure, which dyes comprise one or more ethylenically unsaturated polymerizable groups in an organic group that is attached to the methine chain. These infrared radiation absorbing dyes exhibit a reduced tendency to crystallize in the imageable layers in the presence of tetraaryl borate counter anions and therefore provide improved shelf life.

The approach involves determining one or more image areas associated with printing one or more images, the one or more image areas being positioned on a surface of a substrate. The approach also involves determining a liquid interaction behavior of at least the surface of substrate is one of hydrophobic or hydrophilic. The approach further involves causing, at least in part, a substance that is the other of the determined liquid interaction behavior of the surface of the substrate to be applied to the one or more image areas on the surface of the substrate by a jetting process. In one embodiment, the printing member is mounted inside a printing system when the substance is applied. In one embodiment, the surface may be completely or partially cleaned and a new image created by another application of the substance.
