Abstract
An imaged plate processor for covering the imaged coating with a turbulent flow of fresh developer solution for a short dwell time, and which preferably can be modified by the end user for development of a wide range of plates. The processor comprises a flat support surface for the plate, a plate feeder to the support surface, a plate transporter, and a nozzle array oriented to discharge developer solution onto a plate as the plate moves along the support surface. A source of fresh developer solution is connected to a pump for pressurizing the developer in the nozzle array in the range of about 5 to 250 psi, whereby fresh developer solution is directed from the nozzles as a pressurized flow pattern transversely onto the plate. A continual flow of fresh developer solution impinges on successive areas of the plate. Adjustable variables for accommodating a variety of plates include at least one of spray pressure and plate transport speed.
