Cold Foil Transfer – The web-fed process
In web-fed printing Cold Foil can be applied in Flexo-, Offset printing and letterpress process.
The majority of cold foil jobs are being produced in flexographic printing by using an UV-curing cold foil adhesive which is applied with an anilox roller in a specific volume via a polymer plate onto a substrate.
Immediately thereafter, the Cold Foil web is combined by means of a press roll with the substrate and adhesive. After this step, the UV adhesive is cured through the Cold Foil by UV radiation and the backing material is being removed. The metallized layer of cold foil remains on the areas which previously have been applied with adhesive. In the following printing units the Cold Foil can be inline overprinted and many different multi-colored metallic effects can be achieved individually.

Depending on the absorbency of the used substrate, the adhesive amount must be amended to the right amount by the anilox roller volume and/or gravure if necessary.

The adhesive amount can be controlled very precisely over the used cell volume and the type of anilox roller in flexographic printing.

Benefits

  • The transference of finest details, fonts, large areas and screens is possible in a single run
  • Inline- & Offline overprinting is possible
  • No hot stamping clichés are necessary
  • For the process no heat and no high pressure are required
  • Application on heat sensitive substrates possible
  • 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
  • Also optionally available as a shrink sleeve version  for reverse effects
  • 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

Substrates and adhesives for cold foil applications in web-fed printing
Suitable substrates are, for example, various plastics, such as PP, PET or PE, which are mainly used for self-adhesive labels but also for flexible packaging. Also tube laminates can be enhanced with with Cold Foil. A corona treatment is recommended. For a good overall printing performance a surface tension of >38 dyne is necessary. Coated papers and folding cartons can be also enhanced in web-fed printing. However, very absorbent, uncoated substrates are less suitable for cold stamping suitable because the adhesive penetrates too quickly into the substrate.

Good results can be achieved but with the help of a primer pretreatment, since thus the surface can be closed and the absorbency is reduced simultaneously.
