The Optima features a variety of foil preparation devices, ranging from a straightforward manual frame to a fully automated job preparation system. These tools are crafted to accelerate changeovers and ensure the precise alignment of foil rolls, significantly easing the workload on operators.
With the capability to manage both the unwinding and rewinding reel at the same time, they effectively reduce changeover times by half. This spectrum of foil preparation solutions enhances the Optima’s operational efficiency and competitive edge.

Using a standard offset plate, an image is printed onto a substrate by the use of a tacky adhesive. Foil spools from an unwind and is nipped to a substrate. The aluminium particles from the cold foil layer are released from the polyester film and transferred to the substrate by the tack of the glue.
An image with a bright surface is created on the sheet. Foil that does not adhere to the adhesive remains on the 12um film, and waste is directed to a rewind spool or to a shredder (Vinfoil Infigo systems).
Multiple Foil Use (MFU) is Vinfoil’s patented foil saving technology.
By guiding the foil web back into the printing nip (after transferring parts of the metallic layer for the first time) a foil web can be used up to 3 times during the same job and foil savings up to 85% can be reached. (Compared to full web and laminated board, depending on the job.)
