Cold Foil Transfer – The Sheet-fed Offset process

The Cold Foil transfer is realized using two conventional printing units in an offset printing press. Over the first printing unit a Cold Foil adhesive (adhesive ink) is being applied via an ink unit and a standard offset printing plate / blanket.  Over a second printing unit which is equipped with a suitable Cold Foil module and a roll-off and roll-up station, the Cold Foil is fed into the nip between the blanket cylinder and the impression cylinder and transferred under pressure to the parts on the sheet on which the adhesive has been applied previously.
After separating from the backing material, the metallized transfer layer remains on the substrate and adheres with a special adhesive layer immediately and permanently bonded to the pre-printed Cold Foil adhesive. The substrate is then rewound with the non-transferred areas through the cold foil module. By subsequent and perfectly aligned inline overprinting of the Cold Foil by following printing units or in a separate working step off-line, a large variety of metallic color effects and color shades can be achieved.
Coated papers and folding cartons with smooth and even surfaces provide the best conditions for high-quality Cold Foil results. In addition, non-absorbent substrates such as PP or PE can be used as well.


•    The transference of finest details, fonts, large areas and screens is possible in a single run
•    Inline- & Offline overprinting is possible
•    No hot stamping dies are required
•    For the process no heat and no high pressure are required
•    The surface structure of the printing material is maintained on both sides
•    Very short set-up and make ready times and fast roll and job changes
•    Very high production speeds
•    Compared to metallized substrates no opaque white application is necessary, the white degree of the substrate can be optimally and efficiently used by avoiding the corresponding
•    Foil savings per sheets are possible by the use of certain Cold Foil modules

Printing machines and Cold Foil modules for sheet-fed offset printing

Suitable equipment for cold foiling is available from the major press manufacturers, such as by manroland sheetfed, Heidelberger Druckmaschinen AG or KBA AG. There are also some systems available which can reduce the effective film consumption per sheet, thus making the process as compared to other finishing processes attractive and efficient. Production speeds in sheet-fed Cold Foiling can reach up to 18,000 sheets / hour and are therefore it becomes interesting for large print runs.
In addition to the Cold Foil modules of the printing press manufacturers, Cold Foil modules are available as well from independent manufacturers in the market, which can be installed on many different series of sheet-fed offset printing machines which are being used worldwide.
Depending on the cold foil module, either 3 inch or 6 inch cores are used. Below you will find a list of manufacturers of printing machines and cold foil modules:

Blankets for the Cold Foil transfer

For the Cold Foil application special blankets are used, which with respect to shore hardness and surface texture and roughness are different to standard printing blankets. The following printing blankets have become widely adopted for the cold foil transfer  and are mostly used on many machine series:

SuperPress/BlackPearl (Glassbead blanket) ,Fa. Streb AG
3 Layers, 1,85mm,

Finito Foil , Fa. Streb AG 
1,70mm, 1,95mm

Cold Foil adhesives and substrates

Depending on the printing process, special cold foil adhesive are being used in sheet-fed offset printing machines. In order to achieve a high-quality cold foil application a suitable adhesive type must be used and if necessary as well the tack must be adjusted to the conditions in the press and on that of the printing material. Applying quantities are dependent on the substrate absorbency level between 1.5-3.0 g /m². Gloss coated and cast-coated Paper, label substrates and cartons, are suited for cold foil applications. These types of substrates are mainly used for printed advertising material, wet glue labels and packaging jobs. However, the end result is strongly dependent on the surface properties and from the absorbency of the substrate in use. Uncoated- and matt-coated substrates are not well suitable due to the surface structure and higher absorbency level. But also non-absorbent substrates such as PP or PE can be used for cold-foil applications, but they should not have a surface tension underneath 40 mN / m, in order to achieve good adhesion.
We recommend in advance making a test to ensure that the components used are suitable for your applications and jobs.
