Metallic cold foil — true mirror gold, inline at 450 m/min.

Bright gold, pale gold, champagne, rose gold, copper and silver cold transfer foils for cartons, labels and folding boxes. Up to 92% specular reflectance — indistinguishable from hot-stamped foil, at a fraction of the lead time.

The technology

Why metallic cold foil replaces hot stamping at scale.

Metallic cold foil is built around a vapor-deposited aluminium reflector (typically 30–50 nm) laminated to a 12 µm PET carrier. A pigmented lacquer above the aluminium defines the tone — yellow gold, pale gold, champagne, rose gold, copper. Transfer happens through a UV-cured adhesive printed inline on a flexo or offset plate.

Because no die and no heat are required, run-rates match the press — 450 m/min on a modern UV-flexo line, with no second pass and no tooling lead time. The same job that takes a hot-stamping line three shifts can run in a single offset pass.

Compared to metallic inks, cold foil delivers a true continuous metal reflection (~80–92% specular vs ~30–40% for the best metallic ink). Compared to transfer metallizing, it's selective — only printed where the design needs metal, so paperboard stays mono-material and recyclable.

Finish variants

Four finishes from one metallic foil web.

Mirror finish

Smooth, high-specular metallic surface. Use over coated black, navy or deep brand-color substrates for maximum optical impact.

Satin / brushed

Add a 10–20% screened halftone under the foil to break the mirror into a brushed-metal reading. No second pass required.

Tinted metallic

Over-print 30–60% CMYK on a silver cold-foil base to build any brand-colored metallic — teal, magenta, deep forest.

Matte metallic

Pair with an inline matte OPV to dial back specular reflection. Reads as 'soft luxury' instead of 'shouting metallic'.

Press setup

Five tuning notes for a clean metallic transfer.

  • Anilox 8–11 cm³/m².

    Slightly higher coat-weight than rainbow or holographic. Continuous metallic areas need a uniform adhesive flood to avoid mottling.

  • Substrate matters more than the foil.

    Coated black, navy and deep brand-colored stocks give the most dramatic mirror reading. Uncoated and recycled stocks soften the metal — often desirable for craft and natural brands.

  • UV cure ≥ 200 mJ/cm².

    Under-cured adhesive is the #1 cause of metallic dulling 24–72 hours after the print run. Verify with a tape-pull test before sign-off.

  • Nip pressure: light and even.

    Too much nip flattens the metallic grain and can show paperboard texture through the foil. Calibrate against a 100% coverage swatch.

  • Plan for over-print last.

    If you intend to over-print CMYK on the metallic, build the foil as a single base color (silver for tinted metallics, gold for shadow accents). See our CMYK-over-cold-foil guide.

FAQ

Metallic cold foil — buyer questions.

What is metallic cold foil?+

Metallic cold foil is a cold transfer foil with a thin (<5 g/m²) aluminium reflector — optionally pigmented with gold, rose-gold, copper or other tones — applied inline on a UV-flexo or offset press using a UV-curable adhesive instead of heat and a die. The result is a true metallic finish at full press speed (up to 450 m/min) with no second pass.

How is metallic cold foil different from metallic ink?+

Metallic ink uses ground metallic pigment suspended in a vehicle; reflectance is limited (~30–40%) and the surface is grainy. Cold foil deposits a continuous aluminium layer, giving 80–92% specular reflectance — visually identical to hot-stamped foil — at a fraction of the lead time and tooling cost.

Can metallic cold foil be over-printed with CMYK?+

Yes. CMYK printed inline on top of a silver cold-foil base is how 'metallic teal', 'metallic magenta' and similar brand-colored metallics are built. Typical screen values are 30–60%. See our anilox-selection and CMYK-over-cold-foil guides for press setup.

Is metallic cold foil recyclable?+

With aluminium deposit kept under 5 g/m², cold-foil-decorated mono-material paperboard remains within EU PPWR 2027 recyclability thresholds. We supply technical compliance letters per shipment.

Cold foil or hot foil for metallic finishes?+

For long runs, large coverage areas, fine detail and recyclable mono-material designs, cold foil wins on cost, speed and sustainability. Hot foil still has an edge for very small artwork on thick board where embossed register is required. Our hot vs cold foil guide breaks down the decision.

What is the minimum order quantity?+
