Abstract
A register control device for the cylinder of a printing machine that emits a signal when a printing plate is resting in register on one or more register pins associated with a print cylinder. The signal is communicated to a stationary evaluation unit by a magnetic field. In this regard, a magnetic field sensor is attached to the printing machine frame and is used to detect the signal and forward the signal to the evaluation unit. The evaluation unit uses the communicated signal to determine whether or not insertion of the printing plate was properly performed.
