What a cold foil roll is
A cold foil roll is a slit reel of vacuum-metallised PET film wound onto a 76 mm core, used on UV-flexo, UV-offset and sheetfed offset presses fitted with a cold-foil transfer module. The metallising is released onto a UV-cured adhesive image printed on the substrate — no heat, no die.
- Carrier: PET film, 12 µm / 19 µm (default) / 23 µm.
- Metallising: vacuum-deposited aluminium, optical density 2.2–2.6.
- Colour: pigmented lacquer above the metallising for Pantone Metallic tints; embossed hologram optional.
- Core: 76 mm (3") ID; 152 mm (6") on request for jumbo formats.
- Wind: standard face-out; face-in available for specific press configurations.
