Abstract
Printing material is transported through the multicolor printing machine with a cyclically operating feeding arrangement. At least one surface of the printing material is successively imprinted with a printed image. The printed image is recorded in a image pickup and an image signal of each printed image is generated. The image signal generated from a plurality of printed images is transmitted to a control device. The control device processes the electric image signals to obtain information relating to rhythmic vibrations in the machine causing register deviations. The cause of the vibrations is determined and counter-measures are initiated for minimizing or eliminating the rhythmic vibrations.
