How cold foil
stamping works.

Inline UV-cured metallic decoration at 300 m/min. No heated dies, no offline pass, no compromise on detail. Explore the chemistry, the press integration and the engineering data behind every roll of CFS foil.

Process

Three inline steps. One pass through the press.

Cold foil stamping happens in line with conventional flexo or offset printing — no offline finishing, no second machine, no cooling time.

01

UV Adhesive Print

A flexo or rotogravure unit lays a UV-curable adhesive in the exact shape of the artwork. Image fidelity down to 50 µm is preserved at full press speed.

02

Foil Transfer & Cure

The metallized PET web is nipped against the wet adhesive. UV LED lamps cure instantly, locking the metal layer onto the substrate while the carrier rewinds clean.

03

Inline Overprint

Subsequent CMYK or special-color stations print directly over the foil — enabling tints, gradients and brand color overlays without a second pass.

Construction

Six engineered layers, thinner than a human hair.

Hover or tap any layer of the foil construction to inspect its thickness, function and material chemistry.

FAQ

Questions, answered.

Engineering and procurement questions we hear most often from converters and brand owners evaluating cold foil stamping.

Ask our technical team

Cold foil stamping is an inline decoration process that transfers a metallic layer onto a substrate using a UV-curable adhesive instead of heat and a metal die. The adhesive is printed in the artwork shape, the foil is laminated against it, UV light cures the bond instantly, and the carrier film rewinds — all at full press speed.

Specify cold foil stamping on your next program.
