Flexographic printing machine with simplified adjustment of the side register. The machine comprises a rotating printing drum (1) bearing a printing material (2), and one or more printing units (3), each with a plate-bearing roller (4), an inking roller (5) and an ink supply chamber (6), arranged to change position by moving perpendicularly to the printing drum (1) between a printing position and an inactive position wherein said rollers (4, 5) and separated from each other and the first (4) distanced from the printing material (2). The rollers (4, 5) and the chamber (6) are installed on a support structure (7) mounted on holder elements (9) with portions (9a) housed in guideways (10) parallel to the shafts of the rollers (4, 5) enabling the support structure (7) to move transversely in order to make a transverse register of the plate-bearing roller (4) with respect to the printing material (2). |
