摘要： Excellent development of photosensitive coatings on planographic printing plates is achieved by directing a dynamic flow of fresh alkaline developer solution that impinges on a target area of the coating extending the width of the plate and floods the target area with a turbulent flow. At sufficient volumetric flow rate, the developer solution at the target area is constantly displaced during the development time, whereby no boundary layer forms on and travels with the plate during the development time and thus the target area is always in contact with fresh developer solution.

摘要： A method of on-press development of a lithographic printing plate having an imaged photosensitive (PS) coating by (a) applying an emulsive film of press ink and fountain onto the entire PS coating; (b) transferring all nonimage areas of the inked PS coating and all of the ink film on the nonimage areas of the PS coating from the plate to a blanket roll while the image areas of the PS coating remain on the substrate, wherein the nonimage areas are transferred to the blanket roll in particulate form without dissolution or dispersion in any ink or fountain; and (c) contacting the blanket roll with a paper leader to further transfer all the ink, fountain water, and particles of nonimage PS coating that were transferred to the blanket roll, from the blanket roll to the paper leader.

摘要： On-press development of an imaged printing plate on a plate cylinder, in which ink is applied by an ink form roll, a blanket roll is in contact with the plate, a rubber roll is opposed to the blanket roll, and printable media passes between the blanket roll and the rubber roll. The plate comprises a substrate carrying an imaged coating, in which nonimage areas have cohesion C1, adhesion to the substrate A1, and adhesion to the applied ink A3 and image areas have cohesion C2, adhesion to the substrate A2, and adhesion to the applied ink A4. The ink has cohesion C3 and adhesion A5 to the blanket roll. The nonimage areas have adhesion A6 to the printable medium and the ink has adhesion A7 to the medium. The adhesions and cohesions are such that the blanket roll pulls the ink from the plate and the ink pulls the nonimage areas from the substrate as undissolved particles that are transferred by the blanket with the ink to the printable media.

摘要： Excellent development of planographic printing plates can be achieved by exposing an imaged, negative working, photopolymerizable coating to a high pressure stream of essentially untreated tap water, whereby the water completely removes only the less cohesive and adhesive (e.g., partially polymerized) regions to the substrate, thereby directly producing a printing plate having an image pattern of highly cohesive and adhesive, oleophilic regions of the coating and hydrophilic regions of the substrate. The coating removal mechanism appears to be due entirely to ablation. The high pressure stream is preferably delivered to the plate through at least one nozzle having a discharge pressure greater than about 200 psi. Each nozzle preferably has a spray pattern that impinges the plate over a substantially rectangular region of the plate, and the nozzle and plate translate relative to each other. The nozzle can reciprocate across the width of a longitudinally transported plate, thereby contacting successive regions of the plate in a rastering fashion.
摘要翻译： 平版印刷版的优异发展可以通过将成像的，负性的可光聚合涂层暴露于基本上未处理的自来水的高压流中，由此水完全除去较少的内聚力和粘合剂（例如，部分聚合的）区域 从而直接制造具有高度粘合和粘合的图像图案的印刷版，涂层的亲油区域和基底的亲水区域。 涂层去除机制似乎完全归因于消融。 高压流优选通过具有大于约200psi的排出压力的至少一个喷嘴输送到板。 每个喷嘴优选地具有将板撞击在板的基本矩形区域上的喷射图案，并且喷嘴和板相对于彼此平移。 喷嘴可以横跨纵向传送的板的宽度往复运动，从而以划痕方式接触板的连续区域。

摘要： A printing plate having a substrate and a radiation sensitive, negative working, organic, polymerizable, photosensitive (PS) resin coating non-ionically adhered to the substrate such that the cohesion of the PS coating exceeds the adhesion of the PS coating to the substrate. The PS coating contains active components that participate in radiation induced polymerization, all of which active components are soluble in non-aqueous solvents and none of which active components are soluble or dispersible in any of the group of fluids consisting of water, fountain solution, ink, and press ink. The PS coating has sufficient cohesion and surface tack to adhere to and be mechanically pulled off the substrate by press ink as particulates without dissolution or dispersion into the press ink.

摘要： Excellent development of planographic printing plates can be achieved by exposing an imaged, negative working, photopolymerizable coating to a high pressure stream of essentially heated but otherwise untreated tap water, whereby the water completely removes only the less cohesive and adhesive (e.g., partially polymerized) regions to the substrate, thereby directly producing a printing plate having an image pattern of highly cohesive and adhesive, oleophilic regions of the coating and hydrophilic regions of the substrate. The coating removal mechanism appears to be due entirely to ablation. The process variables of spray pressure, spray volumetric flow rate, and water temperature can be traded off to achieve one or more targets for plate quality, energy conservation, production rate, and equipment availability.

摘要： A novel coating for lithographic printing plates can be imagewise exposed to radiation and then directly processed with only water to remove the non-exposed regions of the coating. The coating comprises a polymer, a monomer and/or oligomer, polymerization or cross link initiator, stabilizer, and dye or pigment, such that after imaging, the non-imaged resin areas are removable from the planar surface by penetration of water through the non-imaged coating without dissolution of the resin components of the coating, to form a lithographic printing plate with clearly defined image and non-image areas. The stabilizer is a solvent soluble, partially water soluble, non-polymerizable organic component that enables the coating to be removable by water in the non-cross linked areas.
