Sheet-fed printing machine for different printing methods

A sheet-fed printing machine comprising:

• at least first and second sheet-fed printing units;
• wherein the first sheet-fed printing unit has a first cylinder of a first type formed as a first impression cylinder and has a second cylinder of the first type and formed as a second impression cylinder, which first and second cylinders of the first type one of have direct contact with one another and are arranged to interact directly with one another and each of which first and second cylinders of the first type has an axis of rotation;
• wherein a first axial plane contains both the axis of rotation of the first cylinder and the axis of rotation of the second cylinder of the first type;
• wherein a first reference plane contains at least an axis of rotation of one of the first and second cylinders of the first type and has a horizontal surface normal;
• wherein the first and second cylinders of the first type are arranged, at least during a processing operation, such that an intersection angle between the first axial plane and the first reference plane is no more than 30°;
• wherein the second sheet-fed printing unit has at least a third cylinder of the first type formed as a third impression cylinder;
• wherein the first and the second impression cylinders of the first sheet-fed printing unit and the at least third impression cylinder of the second sheet-fed printing unit have a same outer circumference;
• wherein the first sheet-fed printing unit has at least one first forme cylinder, which at least one first forme cylinder one of which has direct contact with and is arranged to interact directly with one of the first impression cylinder and with the second impression cylinder and which at least one first forme cylinder is formed as a as a flexo forme cylinder;
• and
• wherein the second sheet-fed printing unit has at least one second forme cylinder, which at least one second forme cylinder one has direct contact with and is arranged to interact directly with at least one of the at least first and second impression cylinder and which at least one second forme cylinder is formed as a numbering forme cylinder.
