Abstract: Printing machines are provided which include a plurality of printing units, each including a cliché-carrying cylinder rotatably mounted about a respective axis of rotation (x) and a cliché fixed to the cliché-carrying cylinder in a given angular position with respect to the latter. The cliché-carrying cylinder of each printing unit has at least one reference mark (N) intended to be aligned with a given reference direction (z) to ensure correct angular positioning of this cliché-carrying cylinder with respect to the cliché-carrying cylinders of the other printing units. Each printing unit comprises a laser source adapted to generate a light beam directed along the reference direction (z) of this printing unit and towards the cliché-carrying cylinder of this printing unit, so that it is easier to perform the operation of aligning the reference mark (N) on the cliché-carrying cylinder with the reference direction (z).
