PURPOSE:To effect a peripheral and axial registration control between each of plate cylinders by a method wherein misregistration of primary color pictures obtained from the picture imaged by a camera which resolves the color printing pattern on a rotary press into the three primary colors in conjunction with a storoboscope is corrected on the display of a computer by simulation. CONSTITUTION:There are provided a computer-containing picture processing device 22 into which is sent a multicolor picture imaged by cameras 21a and 21b into three primary color pictures and which is operated by the command from a main controller 23 and a motor for effecting a peripheral and axial registration control of plate cylinders 2p, 3p, 4p and 5p. Since the multicolor picture blurs in color entirely when the primary color pictures sent into the picture processing device 22 are out of registration, the primary color picture are made to move on the display of the computer contained in the picture processing device 22 to make part of the picture out of registration small to correct the misregistration of the pictures and to eliminate the blur and the amount of each of the primary color pictures moved for this correcting is computed by the computer. According to the amount of the amount of the picture movement thus obtained the motor for effecting a peripheral and axial registration control of plate cylinders 2p-5p is actuated to effect an exact imposition of successive color patterns to be printed on a web. |
