    • 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.
    • 通过将成像的负性可光聚合涂层暴露于基本上加热但未经处理的自来水的高压流,可以实现平版印刷版的优异发展,由此水完全除去较少的内聚和粘合剂(例如,部分聚合的) 区域,从而直接制造具有高粘合性和粘合性的图像图案的印刷版,涂层的亲油性区域和基材的亲水区域。 涂层去除机制似乎完全归因于消融。 喷涂压力,喷雾体积流量和水温的过程变量可以交付,以实现板材质量,节能,生产率和设备可用性的一个或多个目标。

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.
    • 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。
