Abstract
A process for developing an imaged lithographic printing plate, including the step of delivering developing fluid to the plate at a high volumetric flow rate for a short dwell time such that the non-image is completely solubilized while the image remains unaffected by the developing fluid. 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.
