PRINTING DEVICE

PROBLEM TO BE SOLVED: To suppress a defective unfavorable printing due to displacement of an image by adjusting the phase of a printing drum on the downstream side in response to the kind of a printing paper, in a printing device, wherein a plurality of printing drums are arranged with intervals in the carrying direction of the printing paper, and a multi-color printing can be performed by one time of the carrying of the printing paper. SOLUTION: Printing papers P are loaded on a paper-feeding base 24, and are separated and fed by a paper-feeding roller 26 and a separating roller 28 sheet by seed from the top side. Then, the printing paper P is pressed to a plate cylinder 8 on the upstream side by a press roller 12, and an image for a first color is printed. Then, the printing paper P is separated by a separating claw 70, and carried by an intermediate carrying means 14. Then, the printing paper P is pressed to a plate cylinder 10 on the downstream side by a press roller 16 on the downstream side, and an image for a second color is printed. In this case, between the plate cylinders 8 and 10 on both, top and bottom sides, an inter-drum transfer-adjusting means 22 is arranged. The inter-drum transfer-adjusting means 22 is constituted by arranging a large number of deflecting pulleys 44, which perform a phase adjustment by a vertical displacement, between a plurality of pulleys 40 and 42 for the adjustment and drum driving pulleys 92 and 94, in a manner to tighten a timing belt 20.
