Abstract
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.
