PURPOSE:To make the adaptation to a plate having a different dimension, by a method wherein a printing unit is made replaceable between a pair of ink supply devices in a freely detachable manner and the spaced-apart distance between both ink supply devices is made freely adjustable so as to supply ink to the printing unit therebetween. CONSTITUTION:A plurality of printing units are prepared corresponding to the number of cylinder standard dimensions different in a diameter and have different height dimensions. A pair of ink supply devices 7, 8 for supplying inks to a pair of plates are provided so as to be opposed to and spaced apart from each other in an up-and-down direction and can be moved in the up-and- down direction so as to grasp the printing units having the max. and min. cylinder standard dimensions in the opposed and spaced-apart gap. Each of the ink supply devices has a known ink supply mechanism constituted of an ink sump 9, one set of ink supply rollers 10, a water sump 11 and one set of water supply rollers 12. Ink rollers 13, 14 and water rollers 15, 16 for finally supplying inks and water to the plate cylinder 3, 5 of the printing unit 1 from the ink supply devices 7, 8 are constituted so as to be capable of performing pendulum movement. |
