Abstract: The basic press structure includes a printing couple consisting of a lower printing cylinder, having a single work area, and a large printing cylinder, having an effective diameter which is a whole multiple, greater than one, of the effective diameter of the lower printing cylinder, and has a number (equal to the whole multiple) of work areas, in each of which one of a variety of the especially constructed removable and interchangeable segments may be mounted. One of a variety of different printing surfaces may be carried in each of the various work areas on the cylinders of the printing couple, in a wide range of combinations. The printing couple is mounted in a frame structure constructed so as to provide a plurality of module mounting positions, at each of which one of a variety of printing modules may be mounted in cooperative relationship with the large printing cylinder.
