The invention relates to a printing assembly suitable for quickly replacing the sleeves and the inking and printing cylinders in a flexographic printing machine provided with a central drum and controlled by an electronic control unit (EC). The printing assembly comprises a frame (13, 14) supporting an inking sleeve carrying cylinder (18) and a printing sleeve carrying cylinder (20) displaceable close to the central drum (4). The frame (13, 14) comprises a first side (14) on which the said inking sleeve-carrying cylinder and printing sleeve carrying cylinder are overhangingly mounted for rotation about their axes of rotation at a respective end thereof, and a second side (13) spaced from the first side (14) and having a removable support (13a, 13b) for the other end of each of the inking sleeve carrying cylinders and printing sleeve-carrying cylinders so that a sleeve (19,19a) and/or one of or both inking sleeve-carrying cylinder and printing sleeve-carrying cylinder (18, 20) can be replaced after their respective removable support (13a, 13b) has been moved away. <IMAGE>
