VINFOIL OPTIMA® SF80MF & SF110MF system for offset printing machines in the size 700-1100 mm
Optimal Foil Saving feature: MFU®
Perfect foil web tension and positioning at any speed achieved by Vinfoils DFD technique
Changeover time under 6 minutes with ALUS+ and FSC
Speed of up to 18.000 sheets/hour achievable (also with MFU®)
Very low building height and the access to the printing units is optimal
Changing the reels takes place at ground level, which ensures a very easy and safe operation
The sensitive metallic layer of the cold foil is never getting in contact with any part of the Vinfoil Optima® SF80 MF

The principle of the Vinfoil Optima® SF80MF & SF110MF
Continuous foil drive while both cylinder gaps are facing each other by use of the special engineered Direct Foil Drive roller. This Vinfoil technology ensures perfect synchronization of circumference speed of the press with the cold foil web.
Web tension is regulated by software which is feeding data to the following Vinfoils technologies (patent applied):
Servo motion control systems with torque control
Magnetic powder clutches
FT locking shafts
MFU® is redirecting the cold foil web back into the printing nip after transferring parts of the metallic layer for the first time. With this technology, a foil web can be used up to 3 times to generate optimal utilization of the cold foil reel.
It is not necessary to stop and to restart the foil web with every turn of the cylinder-like in systems using indexing.
Multi reel without limitation in quantity of foil cores
