PROBLEM TO BE SOLVED: To solve problems that a one-drum one-pressing means perfecting printing system requires spacing for regulating positions of printed images between a first platemaking image and a second platemaking image formed on a divided platemaking master wound on a plate cylinder, when the case wherein the positions of the printed images are regulated in the top-and-bottom direction along the direction of rotation of the plate cylinder is taken into consideration, and this results in a wasteful increase of consumption of the masters in comparison with conventional equipment. SOLUTION: The perfecting printing equipment 200 has a printing part 16 which has either a conventional plate cylinder 501 having an opening range 501a or a plate cylinder 1 for perfecting printing having an enlarged opening range 1a formed by enlarging the opening range 501a forward in the rotational direction, a press roller 21 which can be brought into contact with and detached from the plate cylinder 501 or 1, a paper refeeding part 45, etc. The range of pressing by the press roller 21 is enlarged forward in the direction of rotation of the plate cylinder, corresponding to the enlarged opening range 1a.
