PURPOSE:To directly superpose base plates after pictures are formed, and to wind the base plates, by providing a reexposing section behind a strippable developing device. CONSTITUTION:A pair of base plate carrying belts 7, whose interval between each other is changeable in accordance with the width D of a base plate, is provided on the base plate carrying-out port side of a double-face strippable developing machine 5 and reexposing sections 6a and 6b which can photopolymerize a photopolymerized substance layer are provided above and below the belts 7. An exposed base plate 4a to be processed is put into the developing machine 5 and upper and lower surfaces of the base plate 4a are respectively subjected to developing processes. Thus prescribed pictures are formed. The processes base plate 4b is carried out from the developing machine 5 and is advanced under a condition where its both sides are held by the belts 7. In such case, the upper and lower surfaces of the base plate 4b are irradiated by the reexposing sections 6a and 6b at the optimum exposing light quantities and their unexposed parts 3 are photopolimerized. After the photopolimerization, the unexposed parts 3 become equal to exposed parts 2 in property and the tackiness is reduced. Therefore, the reexposed base plate 4c can be superposed. |
