面倒だった。However, in the plate cylinder 1 shown in FIG. 4, when the plate material 3 is mounted on the body 2, the mounting position of the plate material 3 is likely to be incorrect. Therefore, when performing multicolor printing or the like using the plate cylinder 1, so-called misregistration is likely to occur. Further, when printing is performed using the plate cylinder 5 shown in FIG. 5, the misregistration due to the above-mentioned displacement of the plate material attachment position is unlikely to occur. However, when replacing the plate, the entire plate cylinder 5 had to be removed from the printing machine and replaced, which made the plate replacement troublesome.
