Abstract
An offset printing head includes, mounted to rotate parallel to each other and spaced from each other on a common carriage that is itself mounted to be mobile in translation on a frame, an inking roller and a blanket cylinder. As it moves to and fro, the carriage sweeps across a plate support which receives a plate and an object support which receives an object to be printed. The inking roller and/or the blanket cylinder are each driven by an individual drive system specific to it and independent of the movement of the carriage. Applications include printing machines combining an offset printing head with a silkscreen printing head.
