Abstract
A printing plate processor for processing a printing plate having a substrate, a hydrophilic layer over the substrate and a processable ink-receiving layer over the hydrophilic layer includes a structure for receiving processing fluid and a roller partially submerged in the processing fluid. The roller is rotated so that processing fluid coats the roller and is carried by surface tension around the roller, and the printing plate is moved into a processing region with the rotating roller but spaced from the roller a distance selected so that the turbulence of the processing fluid engaging the ink-receiving layer causes portions of the ink-receiving layer to be removed by the processing fluid carried on the roller.
