Printing press with replaceable units allowing for different methods of printing

System for producing three-dimensional, imprinted structures on a substrate, comprising:

• a sheet-fed printing press having a machine frame, said machine frame including a plurality of stations;
• a plurality of replaceable modular units being mounted and removed from each of said stations on said machine frame, each of said replaceable modular units selected from the group consisting of a printing unit, a substrate turning unit, a substrate further-transporting unit and a substrate perforating unit mounted on one of said stations of said machine frame for producing a three-dimensional, imprinted structure on a substrate;
• a feeder and a delivery for the substrate mounted on said machine frame;
• at least one transport device mounted on said machine frame for transporting the substrate from said feeder to said delivery via said replaceable modular unit for producing the three-dimensional structure;
• an electronic data processor for controlling said replaceable unit, said feeder, said at least one transport device and said delivery for producing the three-dimensional structure;
• and
• said plurality of replaceable modular units each having identical standard plug connectors for a power supply and a data exchange with said electronic data processor and being releasably mounted on said stations of said machine frame for exchanging one of said replaceable modular units with another one of said replaceable modular units selected from the group consisting of a printing unit, a substrate turning unit, a substrate further-transporting unit and a substrate perforating unit for producing the three-dimensional structure on the substrate.

System for producing three-dimensional, imprinted structures on a substrate, comprising:

• a sheet-fed printing press having a machine frame, said machine frame including a plurality of stations;
• a first replaceable printing unit operating in accordance with a first printing method and a second replaceable printing unit operating in accordance with a second printing method for producing a three-dimensional, imprinted structure on a substrate, said first replaceable printing unit releasably
• mounted on one of said stations of said machine frame for exchanging said first replaceable printing unit with said second replaceable printing unit;
• a feeder and a delivery for the substrate mounted on said machine frame;
• at least one transport device mounted on said machine frame for transporting the substrate from said feeder to said delivery via said first replaceable printing unit for producing the three-dimensional structure;
• and
• an electronic data processor for controlling said first replaceable printing unit, said feeder, said at least one transport device and said delivery for producing the three-dimensional structure.
