1. Printing machine with hybrid printing technology for printing a continuous material web, comprising:
a rotating central cylinder, on the surface of which the material web is guided from a placement point to a separation point for printing, wherein a plurality of inking units for digital printing of the material web are arranged in the region of an upper half of the central cylinder and a plurality of inking units for flexographic printing of the material web are arranged in the region of a lower half of the central cylinder;
an unwinding station for unwinding the material web to be printed from a roll and a winding station for winding the printed material web onto a roll, wherein the unwinding station and the winding station are arranged on a first side of the central cylinder;
supply guide rollers for feeding the material web unwound from the unwinding station to the central cylinder and discharge guide rollers for discharging the printed material web from the central cylinder to the winding station, wherein the supply guide rollers and the discharge guide rollers are arranged on a second side of the central cylinder,
feed guide roller for placing the material web onto the central cylinder at the placement point and a strip guide roller for detaching the material web from the central cylinder, wherein the feed guide roller and the strip guide roller are designed in such a way that the placement point and the separation point are arranged on the lower quadrant of the guide cylinder.
