Abstract

The present invention generally describes register control equipment for the cylinder of a printing machine. It specifically pertains to the printing plate of sheet-fed offset printing machine that has fitted register pins. The register pins are electrically insulated with respect to the cylinder and emit a signal when a printing plate is resting in register on one or more of the pins. The signal is communicated to a stationary evaluation unit by an electrical contact adapted to contact the printing plate. The evaluation unit uses the communicated signal to determine whether or not insertion was properly performed.
