A multicolor offset perfecting press comprising a printing station having offset cylinders, plate cylinders in contact and operatively associated with the offset cylinders, and compression cylinders and at least one intermediate cylinder both having their diameters threefold larger than those of the offset cylinders. The printing station comprises at least a pair of back side printing units and at least a pair of top side printing units arranged to be successively in contact and operatively associated together. Each of the back side printing units is adapted to be horizontally in contact and operatively associated, on one side, with one of the compression cylinders and in contact and operatively associated, on the other side, with vertically paired offset cylinders. Each of the top side printing units is adapted to be horizontally in contact and operatively associated, on one side, with the intermediate cylinder and horizontally in contact and operatively associated, on the other side, with the intermediate cylinder or one of the compression cylinder of the back side printing unit. The pairs of offset cylinders are horizontally spaced from each other to be in contact and operatively associated from obliquely above with the respective compression cylinders lying on the feeder side and the delivery side. The multicolor offset perfecting press also includes a feeder station that has a feeder cylinder in contact and operatively associated from obliquely above with the compression cylinder lying on the feeder side. A delivery station is further included having a delivery cylinder in contact and operatively associated from obliquely above with the compression cylinder lying on the delivery side.
