Abstract
PURPOSE:To provide an apparatus enabling automatic and quick correction of deviation in color by controlling the driving of a phase correcting motor based on the output of a pulse generator for generating pulses in the number corresponding to the phase displacement of a printing cylinder. CONSTITUTION:Printing sections 4 and 5 are equipped with phase correcting mechanisms 17a and 17b for shifting the phases of printing cylinders 9, 10, 13 and 14 longitudinally in the direction of transferring a web 2 and phase correcting mechanisms 17c and 17d for shifting them vertically in the direction. Each correcting mechanism has a variable speed phase correction motors 25 and 26, a pulse generator 25a for generating pulses according to the rotational frequency of the rotating shaft thereof and a control circuit for controlling the driving of the phase correction motors based on the output of the pulse generator.
