• pressure-regulating of the feeding rolls at the feeding unit;
• pressure-regulating of the transport rolls of the printing units;
• pressure-regulating of the anilox roll.

The printing machine can be installed in-line with a SPO automatic flat-bed die-cutter by means of a belt conveyor system or off-line with an automatic stacker. The “in-line” configuration allows to print and die-cut sheets at the same time in one single pass.
