An innovative system is used for print rolls allowing for immediate fitting of cylinders of different diameter with no need for an adapter. In fact print rolls lay on a special algorithmical-studied curve that ables to keep constant the printing pressure varying the roll diameter.
The plate cylinder is pneumatically clamped with a conical piston that grants irreversibility of motion and reduces motions and vibrations to a minimum.
The blade is pressured against the anilox roller with pneumatical system, determining an auto-adaptive pressure dynamic, resulting in the best ink distribution.
When the machine stops, the ink roller (anilox) is first removed, followed (after a settable time) by the print cylinder, in order to clean ink in excess (an essential operation when using non-UV inks).
