Abstract (en)

[origin: EP0806294A2] The method uses a harmonic drive (22) controlled via a central control device (40) in dependence on the measured difference between the rotation of the printing plate sleeve and the printing machine rotation rate. The drive corrects the rotation of the plate cylinder (10) fitted with the printing plate sleeve, for eliminating the detected rotation difference. The rotation rate of the printing plate sleeve can be detected by optical detection of peripheral register markings, e.g. using the detected time interval between the detection of two successive register markings.
