Abstract
An automatic register control system for multi-color rotary presses having adjusting means for adjusting the phase on a plate cylinder of each printing section, comprising a registering error detecting device that reads register marks each printed on a traveling paper web by each printing section with a CCD camera as image data, corrects the image data using inherent correcting means, and detects the characteristic points of the register marks as their coordinates to detect a deviation between the actual coordinates of the detected characteristic points and the desired coordinates thereof, and adjusting signal output means for outputting an adjusting signal to the adjusting means to adjust the phase of the plate cylinder in each printing section on the basis of the deviation detected by the registering error detecting device, thereby automatically adjusting registering errors in the multi-color rotary press.
