Abstract: A machine for processing image-wise exposed light sensitive plates comprises processing rollers for agitating developer liquid in contact with the plate as the plate passes through the machine. The plate is urged into contact with the rollers by a plate member which is preferably adjustable and provided with recesses and preferably the developer applied to the plate is filtered developer and is applied by spraying. After developer has been removed, the plate is urged into contact with a roller, dipped in desensitizing solution, by means of, for example, a preferably adjustable second plate member. The desensitized developed plate is then dried before leaving the machine.
