1. A drive for a rotary offset printing press comprising:
- printing units having a first pair of cylinders (3, 13, 67) for transferring ink including a first form cylinder (1.1, 1.4, 69) and a first transfer cylinder (2.1, 2.4, 71) which are mechanically coupled and drivable via a first motor (7, 198), a second pair of cylinders (4, 14, 68) for transferring ink including a second form cylinder (1.2, 1.5, 70) and a second transfer cylinder (2.2, 2.5, 72) which are mechanically coupled and drivable via a second motor (7, 200);
each said form cylinder (1.1, 1.2, 1.4, 1.5, 69, 70) being associated with an inking unit and a damping unit;
a computer motor control and memory unit (56, 57, 73, 74) for controlling the position of the motors (7, 198, 200);
said first and second motors driving said transfer cylinders (71, 72) and said transfer cylinders driving said respective form cylinders (69, 70) via a meshing;
or said first and second motors driving said form cylinders (1.1, 1.2, 1.4, 1.5) and said form cylinders (1.1, 1.2, ,1.4, 1.5) driving said respective transfer cylinders (2.1, 2.2, 2.4, 2.5) via a meshing;
functional units (28, 29, 30, 31, 32, 26, 27, 27.1) disposed outside said printing units (21, 22, 23, 24) along a web (155) to be printed, said functional units comprising one or more rollers or cylinders (28, 29, 30, 31, 32, 145, 146, 148), said rollers or cylinders being drivable individually or collectively by a motor for the functional unit (28, 29, 30, 31, 32, 26, 27, 27.1).
