cold transfer technology

vinfoil’s cold Transfer technology

Cold transfer is a modern method of applying metallic particles to a substrate to add metallic effects and value to the final product. Cold transfer is a common technology in the offset printing industry.

We offer the best and most profitable machines in the world for the cold transfer packaging printer

how it works

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 are nipped to a substrate. The aluminum 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 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.

how it works

Step 1

Application of the glue

A tacky glue with the same rheology and consistency like an offset ink is printed on top of the substrate in the first printing unit by the use of a conventional offset plate. Depending on the color of the cold foil the glue is shaded yellow (golden foil) or grey (silver foil) and can be measured with a densitometer or spectrometer to ensure optimal layer thickness.

Step 2

Transfer of the metalized layer

In the pressure nip between blanket and impression cylinder, the foil web is pressed upon the substrate and the metalized layer is sticking to the areas where the cold foil glue has been applied before.

Step 3

Release and rewinding of the foil

The backing film containing the particles which were not transferred to the substrate is released from the sheet and rewound to an empty core or in case of Vinfoil’s Infigo shred and sucked away. In the areas where the glue has been applied to the substrate the metalized layer will adhere to the sheet due to the tack of the cold foil glue.

hot foil vs Cold transfer technology

With both hot foil stamping and cold transfer technology being eco-friendly printing techniques, why should you choose cold transfer? Well, let us explain:

Cold transfer can be done inline, at a maximum speed of 20.000 sheets per hour. Compared to the hot foil stamping process, where it is impossible to do it inline and where the maximum speed only is 4.500 sheets per hour, cold transfer technology is much more efficient.

By using standard offset plates, which can be created fast, it is also less expensive than hot foil stamping where you need customized and expensive dies to start the process.

So, cold transfer technology is great in optimizing your business and profit simultaneously.
