types of machines


In graphic arts industry UV film casting is used as a technology to transfer holographic patterns on top of printed images. Different from cold transfer there’s no transfer layer being applied to the sheet. It is more or less a micro embossing of a holographic pattern.
As the holographic pattern is “embossed” into the coating surface, pressure from the following units will flatten this effect and make it disappear. This is why the technology is used very often in the last coating unit at the end of the press. When applying the effect in a different section of the press
(e.g. printing unit) the pressure in the following units should be switched off.

Step 1

Application of UV Coating

The UV coating can be applied partly or in solids from a printing unit using an offset plate or from a coating unit using a stripped blanket or a flexo plate.

Step 2

Transfer of holographic Pattern & UV Coating

During the transfer of the pattern the holographic texture of the foil comes in contact with the wet UV coating on top of the printing sheet. During this contact the UV coating is being cured through the transparent holographic film. The result is a vice versa of the holographic film pattern on the printed sheet.

Step 3

Release and rewinding of the foil

After the pattern has been transferred and the UV coating has been cured the plastic film is released from the sheet surface. The plastic film for UV film casting can be used multiple times, until the pattern on the plastic is fading away or the plastic film gets worn. The number of passes is depending on different parameters such as intensity of UV rays, type of coating, amount of coating etc.

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).

Because the adhesive is applied like a conventional ink, no expensive stamping die has to be created. Once printed, the surface of cold foil images may be overprinted and varnished.
  • Enables full-surface sheet decoration at high speeds
  • High-speed applications up to 20,000 sheets per hour overprinting can be done inline and offline
  • Eliminates the need for engraved hot stamping dies
  • Allows use of standard offset printing plates, rollers, washing agents, rubber blankets for applying the adhesive
  • Using multiple parallel-running, narrow foil rolls, the foil consumption can be minimized and made more economical
  • Job changeovers, with or without foil, can be performed in just minutes
  • No need to apply opaque white – the foil is simply omitted in the relevant areas
  • Outstanding flatness of the output – optimal further processing
  • Speed-to-market potential – very short production times
  • Ideal for small print runs and frequent job changeovers

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.)


“The very easy handling of the Optima® as well as the reduction of the foil consumption were two of the main reasons for this decision. Furthermore it was very important to have the latest production technology with one of the best price-performance ratios.”
