<P>PROBLEM TO BE SOLVED: To provide a drive control method of a printing machine, which performs synchronous control of a first and a second transfer cylinders to deliver papers at a precise position whenever a printed matter is delivered from an offset printing section to an intaglio printing section, with an improved operation rate while preventing printing faults. <P>SOLUTION: The offset printing section 20 and the intaglio printing section 30 are controlled synchronously while driving the printing sections with an offset printing section motor 1A and an intaglio printing section motor 1B individually. In addition to the rotary/encoders 8A, 8C for the offset printing section motor and the intaglio printing section motor, further rotary/encoders 8B, 8D are provided to the transfer cylinder 23e positioned last in the offset printing section and to the transfer cylinder 23f positioned first in the intaglio printing section. Thereby, the rotation speeds of the offset printing section motor 1A and the intaglio printing section motor 1B are corrected in response to the difference between the rotary phase where the respective printing sections 20, 30 should be positioned and the actual rotary phase where the transfer cylinder 23e is positioned last in the offset printing section and the transfer cylinder 23f is positioned first in the intaglio printing section. <P>COPYRIGHT: (C)2011,JPO&INPIT |
