Abstract

A pressure cylinder is accommodated in a printing assembly and provided with electrostatically assisted ink transfer. Its shaft is mounted in the framework of a printing press. It has a semiconductive jacket that is mounted over a steel surface and can be electrically charged. The shaft is electrically connected to the surface of the cylinder and electrically insulated from the framework. An electric potential can be applied to the shaft in order to charge the semiconductive jacket.
