Abstract:
1. A sucker capable of suction-adhering a printing plate and a protective sheet interposed between the sucker and the printing plate, the sucker comprising: a main body portion integrally including a mounting base portion and including a suction-adherence surface; and a skirt portion attached at the suction-adherence surface side of the main body portion, said skirt portion being configured so as to closely correspond with the protective sheet during a suction-adherence operation of the printing plate, wherein the main body portion includes a predetermined stiffness for reducing deformation of the main body portion and preventing relative movement between the protective sheet and the printing plate during the suction-adherence operation; and wherein the skirt portion is configured with a predetermined resilience such that, during the suction-adherence operation, a surface of the skirt portion that closely corresponds with the protective sheet is substantially parallel to the suction-adherence surface of the main body portion.
