Abstract: PURPOSE:To simplify an adjustment operation for registration by providing optical sensors which detect that a stage loaded with a jig has reached to a position where through holes of the jig are overlapped with register marks by moving relatively to a plate cylinder. CONSTITUTION:Right below a plate cylinder 1, optical sensors 16 are disposed. When a plate 2 is replaced, the plate 2 is wound around the plate cylinder 1 so that edges 31, 32 of the plats 2 are abutted along reference pins 41, 42, 43. After that, movable pins 131, 132, 133 of a stage 12 are made movable, a jig 9 is loaded on a board surface, and the stage 12 is slidingly moved, whereby the plate cylinder 1 is synchronously rotated. When register marks 111, 112, 113 have reached right above the optical sensors 16, the jig 9 is traveled on the board surface to a position where the respective register marks are allowed to be seen through the optical sensors 16, the movable pins 131, 132, 131 are securely abutted against edges 101, 102 of the jig 9, and the jig 9 is detached from the board surface. Therefore, by one registering operation, a registration of printing pattern can be performed between the plate and a body to be printed.
