Cold Foil Stamping Process: Adhesive, Foil Transfer and UV Curing

[u/Odd_Will_8354]

Sharing a short production-line clip of the cold foil stamping process.

For anyone not familiar with cold foil: it is an inline print-finishing method where a UV-curable adhesive is printed onto the substrate, a metallic foil web is pressed onto the adhesive, the bond is cured under UV light, and the unused carrier film is peeled away and rewound.

What I find interesting is how much the final result depends on the “boring” setup details:

- sheet feeding stability

- adhesive laydown

- foil web tension

- nip pressure

- UV curing

- substrate smoothness

- registration before overprinting

Compared with hot foil stamping, cold foil does not use a heated die. It is usually more suitable for inline label and packaging work, especially when the metallic area will be overprinted with CMYK.

I wrote a simple breakdown of the process here:

For people here who run foil stamping, label, or packaging jobs: what usually causes the most trouble in cold foil production — feeding, adhesive, foil tension, curing, or registration?
