PROBLEM TO BE SOLVED: To provide a single process perfecting printing device, which can perform one-sided printing without employing a wasteful master and, at the same time, can get a printed matter with a favorable image quality at perfecting printing and can suppress the increase of an installation space. SOLUTION: This perfecting printing device 1 has a printing part 2 with a plate cylinder 12 wound by two split plate making masters thereabout and a press roller 13, a paper feeding part 4, a paper delivering part 6, an auxiliary tray 8 for temporarily storing a paper with one printed side, a paper refeeding means 9 for refeeding paper P from the auxiliary tray 8 and a changing-over member 10 for guiding either to the auxiliary tray 8 or to the paper delivering part 6 so as to print an image on the front surface of the first paper P1 sent from the paper feeding part 4 at perfecting. After the paper P1 is guided by the changing-over member 10 to the auxiliary tray 8, the second paper P2 is fed to the printing part 2 so as to print another image on the front surface of P2 and, at the same time, the paper P1 is refed by the paper refeeding means 9 so as to print its rear surface. Finally, the paper P1 is guided to the paper delivering part 6 and the paper P2 is guided to the auxiliary tray 8 by the changing-over member 10. COPYRIGHT: (C)2003,JPO
