There is described a sheet-fed rotary printing press (100; 200; 300) for the production of banknotes and like securities comprising at least one printing form cylinder (115, 125; 215; 315, 325) having one or more segments. A nominal diameter (D) of the at least one printing form cylinder (115, 125; 215; 315, 325) substantially corresponds to an integer multiple of a reference diameter of a one-segment cylinder (103a; 103c; . . . ) as used for printing onto super-format sheets exhibiting a standardized format with a width of the order of 820 mm and a length of the order of 700 mm. An axial length (AL) of the at least one printing form cylinder (115, 125; 215; 315, 325) is comparatively greater than a nominal axial length of a corresponding printing form cylinder as used for printing onto super-format sheets, by an amount such that the at least one printing form cylinder (115, 125; 215; 315, 325) is suitable for printing onto large-format sheets having a comparatively greater width (W) than the width of super-format sheets. Preferably, a circumferential length (SL) of each segment of the at least one printing form cylinder (115, 125; 215; 315, 325) is comparatively greater than a nominal circumferential length of each segment of a corresponding printing form cylinder as used for printing onto super-format sheets, by an amount such that the at least one printing form cylinder (115, 125; 215; 315, 325) is suitable for printing onto large-format sheets having a comparatively greater length (L) than the length of super-format sheets. |
