A printing press, in particular for flexographic printing, comprising an unwinder (4) for unwinding a roll (6) of sheet material (8) to be printed and a winder (5) for winding a roll (6) of printed sheet material, which is conveyed round a drum (14) along the periphery of which is distributed a plurality of inking units (12), each comprising an inking or anilox cylinder (13) and a printing or plate cylinder (14), both the drum (10) and the cylinders (13, 14) of each inking unit (12) being supported by a pair of sides (11), at least one of said sides (11) being provided with at least one mobile shoulder (15) that can turn around a hinge (16), so that it can be brought from a closed operating position in which it co-operates in supporting said inking units (12), to an open position in which it completely frees the cylinder (13, 14) of the inking traits (12) which continue to be supported in cantilever by the other side (11).
