PURPOSE: To simplify the construction of an impression cylinder by enabling the gathering immediately after the printing on a plurality of printing papers with a plurality of grippers which are adapted to sequentially grip the papers prepared at a paper delivery section as pregathered.

CONSTITUTION: A printing section B has an impression cylinder C, a plate cylinder D in cooperation therewith and an inking apparatus E for feeding ink to the plate cylinder. Papers 1p, 2p, 3p and 4p are fed separately to grippers 1c, 2c, 3c and 4c. The inking apparatus E has inking devices 1e, 2e, 3e and 4e arranged like satellites about the plate cylinder D to supply separate inks corresponding to plates 1d, 2d... of patterns on the plate cylinder D. A plurality of papers 1p, 2p... fed sequentially from a paper delivery section A are gripped with grippers 1c, 2c... on the impression cylinder C in the order of the gathering. With the rotatry contact betwen the impression cylinder c and the plate cylinder D, separate patterns are printed on the papers 1p, 2p... corresponding to patterns 1d, 2d... on the plate cylinder D.
