Abstract
A multi-color printing press having a single segmented impression cylinder with multiple, segmented blanket cylinders of equal diameter arranged about the periphery thereof. The segments of the impression cylinder and the blanket cylinders are equal in length and the number of segments on the impression cylinder is equal to the number of segments on the blanket cylinders multiplied by a whole number, plus one additional segment. Each blanket cylinder is provided with a plate cylinder of equal diameter which has the same number of segments. Color rolls provide each segment of the plate cylinder with a different color. Sheets to be printed are fed to the gripping means on the successive segments of the impression cylinder and delivery means removes sheets after printing. Each sheet is held on the impression cylinder for a number of revolutions equal to the number of segments on any one blanket cylinder.
