A satellite printing unit having reduced vibrations for a web-fed printing press with printing couples is disclosed. Each printing couple includes a plate cylinder and a transfer cylinder where the transfer cylinders of the printing couples roll off a common impression cylinder. Each plate cylinder features a high lockup slot and a low lockup slot and each transfer cylinder has a lockup slot. The transfer cylinders of the printing couples are aligned relative to the plate cylinders of the printing couples such that, on a first group of printing couples, which includes at least one printing couple, the lockup slot of the respective transfer cylinder rolls over the high lockup slot of the respective plate cylinder and on a second group of printing couples, which includes at least one printing couple, the lockup slot of the respective transfer cylinder rolls over the low lockup slot of the respective plate cylinder.
