Abstract

A printing unit has a printing form cylinder. A plate changer is arranged in a manner which is allocated to the printing form cylinder. The plate changer has a bearing surface on which a printing form, which is arranged or is to be arranged on the printing form cylinder, can be laid. That bearing surface is arranged such that it can be moved to and fro between at least two defined positions longitudinally with respect to the rotational axis of the printing form cylinder. The printing form is arranged and registered on the bearing surface of the plate changer. At least two edges of a carrier for the relevant printing form, which are arranged at a right angle with respect to each other, are brought into physical contact with register pins which are arranged on the bearing surface of the plate changer. A first edge of the carrier of the relevant printing form is arranged to bear against a first register pin and a second edge, orthogonal with respect to the first edge, of the carrier of the relevant printing form, is arranged to bear against a second register pin. The printing unit is preferably arranged as a device for printing hollow bodies.
