A proof printing press (100) includes an impression cylinder (111), a collecting cylinder (113), and a wiping roller (118), which are positioned relative to a plate cylinder (112) such that a length (L11) of an outer circumference of the plate cylinder (112) at a downstream side of a facing position (P1) in a rotation direction of the plate cylinder (112) is longer than a length (L2) in a circumferential direction of a mounting surface (112a) of the plate cylinder (112), where the length (L11) of the outer circumference of the plate cylinder (112) extends between the facing position (P1) where the plate cylinder (112) faces the collecting cylinder (113) and a facing position (P2) where the plate cylinder (112) faces the wiping roller (118), and that a length (L12) of the outer circumference of the plate cylinder (112) at a downstream side of the facing position (P2) in the rotation direction of the plate cylinder (112) is longer than the length (L2) in the circumferential direction of the mounting surface (112a) of the plate cylinder (112), where the length (L12) of the outer circumference of the plate cylinder (112) extends between the facing position (P2) where the plate cylinder (112) faces the wiping roller (118) and a facing position (P3) where the plate cylinder (112) faces the impression cylinder (111). |
