PROBLEM TO BE SOLVED: To provide a double-side printing apparatus capable of reducing a consumption amount of stencil base paper when further performing double-side printing processing for additional printing after end of double-side printing processing.SOLUTION: A double-side printing apparatus includes a double-side printing mode, and a double-side additional printing mode for further subjecting a first print image and a second print image to double-side printing processing on paper after double-side printing processing, and thereby performing double-side additional printing processing of an optional set number of sheets. In the double-side additional printing processing, either of the first print image and the second print image is subjected to print processing on one surface of paper by using either a first plate-making master or a second plate-making master mounted on a print drum 41 just before executing the double-side additional printing processing; thereafter a third plate-making master having the other of the first print image and the second print image re-formed thereon is mounted on the print drum; and the other of the first print image and the second print image is subjected to printing processing on the other surface of the paper. |
