Quick answer (lead block): Cold foil stamping is an inline printing process that transfers a thin layer of metallized polyester foil onto a substrate using a UV-curable adhesive applied via a printing plate at room temperature — no heated die, no engraved tooling. The adhesive is printed only where the metallic image is wanted, foil is laminated over it under a nip roller, UV lamps cure the adhesive in milliseconds, and the unused foil peels away. Cold foil runs at 150–300 m/min, costs 35–60% less per impression than hot stamping on runs above 25,000, and allows full CMYK overprinting in the same press pass.
What is cold foil stamping? (definition)
Cold foil stamping — also called cold foil transfer, inline cold foiling, or simply cold foiling — is a decorative printing technique that applies a metallic or holographic finish to paper, board, film, or foil substrates without heat and without a metal die. Instead of the heated brass die used in traditional hot stamping, cold foil relies on two things: a flexo or offset printing plate that lays down a UV-curable adhesive in the exact shape of the artwork, and a cold foil web that is pressed onto the wet adhesive and instantly cured under UV lamps.
Because the process is inline — integrated into a printing press rather than run as a separate finishing step — cold foil delivers metallic decoration at the same speed as normal printing, and the foil area can be overprinted with CMYK inks in later units of the press to create colored metallics (gold, copper, rose, teal, etc.) from a single silver foil.
“"Cold foil transfer is the fastest, most cost-efficient way to add metallic decoration to packaging at commercial scale — it turns what used to be a specialty finishing operation into just another print unit." — FTA (Flexographic Technical Association), Cold Foil Best Practices
How cold foil stamping works (step by step)
The process happens in four inline stations on a single press pass:
- 1Adhesive printing. A flexo or offset plate transfers a UV-curable adhesive onto the substrate in the exact shape of the artwork — text, logo, pattern, or full flood.
- 2Foil lamination. A continuous web of metallized PET foil (typically 12–23 microns thick) is unwound and pressed against the adhesive-coated substrate under a nip roller at 2–6 bar of pressure.
- 3UV curing. UV-LED or mercury-arc lamps cure the adhesive in 50–200 milliseconds, permanently bonding the metallic layer to the substrate wherever adhesive was printed.
- 4Foil web rewind. The unused foil — everything outside the printed image area — peels off cleanly and rewinds onto a take-up reel for recycling or disposal.
After the foil station, the substrate continues through the remaining print units, where CMYK inks can overprint the metallic area to shift its color, add texture, or combine with process artwork — all in the same press pass.
Cold foil vs hot foil vs digital foil: at a glance
| Attribute | Cold Foil Stamping | Hot Foil Stamping | Digital Foil (e.g. Scodix) |
|---|---|---|---|
| Tooling | Flexo/offset plate (~$80–$300) | Engraved brass or magnesium die (~$150–$1,200) | None |
| Heat required | No (ambient) | Yes (100–150 °C) | No |
| Press speed | 150–300 m/min | 30–80 m/min | 20–60 sheets/min |
| Best run length | 10,000+ | 500–50,000 | 1–3,000 |
| CMYK overprint | Yes (inline) | Limited (offline) | Yes |
| Registration accuracy | ±0.15 mm | ±0.10 mm | ±0.05 mm |
| Cost per 1,000 units (at 100k run) | $18–$32 | $45–$78 | $120–$240 |
| Fine detail (< 0.3 pt) | Good | Excellent | Excellent |
Bottom line: Cold foil wins on speed, cost, and CMYK integration for long runs. Hot foil wins on fine detail, embossed relief, and short-run flexibility. Digital foil wins on zero setup and personalization for very short runs.

Where cold foil stamping is used
Cold foil is now the dominant metallic decoration process for flexible packaging and pressure-sensitive labels worldwide. According to Smithers' 2025 Future of Metallic Effects report, cold foil accounts for ~62% of all metallized decoration in flexo label production and is growing 6.8% CAGR through 2028.
Typical applications include:
- Beverage labels — beer, wine, spirits, energy drinks (metallic sunbursts, foil borders, brand marks)
- Beauty and personal care — shampoo, cosmetics, fragrance cartons
- Confectionery and snack packaging — chocolate wrappers, premium biscuit boxes
- Nutraceutical and pharma cartons — brand differentiation and anti-counterfeit patterns
- Greeting cards, gift wrap, and stationery — full-flood metallic backgrounds
- Security and authentication — holographic cold foil on tickets, tax stamps, IDs
What substrates and inks work with cold foil?
Cold foil bonds best to smooth, low-porosity surfaces. The following table summarizes suitability:
| Substrate | Suitability | Notes |
|---|---|---|
| BOPP film | Excellent | Standard for pressure-sensitive labels — see our Cold Foil on BOPP Labels guide |
| PET film | Excellent | Widely used for premium labels |
| Coated paper (SBS, C1S, C2S) | Excellent | Requires ≥ 120 gsm and calendered surface |
| Uncoated paper | Poor | Absorbs adhesive — foil coverage suffers |
| Kraft board | Fair | Needs pre-coating or primer |
| Metallic substrates | Not recommended | Adhesion issues; use hot foil instead |
UV inks must be cold-foil compatible — some standard UV formulations inhibit adhesive cure or leave a residue that prevents foil adhesion. Always request a cold-foil compatibility statement from your ink supplier, or use a certified UV cold foil adhesive system.
Cost, run length, and economics
Cold foil's cost advantage comes from eliminating tooling and eliminating a finishing pass. A typical cost curve versus hot foil:
- Setup cost: cold foil ~$120–$350 (plate + web setup) vs hot foil ~$250–$1,500 (die + press setup).
- Per-impression cost above 25,000 sheets: cold foil is 35–60% cheaper.
- Break-even run length vs hot foil: typically 8,000–15,000 impressions depending on coverage.
- Per-impression cost below 3,000: hot foil or digital foil wins because cold foil's foil-web waste dominates.

Design rules for cold foil artwork
To get clean cold foil results, designers should follow these limits:
- Minimum line weight: 0.25 pt (0.09 mm)
- Minimum text size: 5 pt for sans-serif, 6 pt for serif
- Minimum negative space between foil elements: 0.3 mm
- Maximum coverage per plate: 85% (higher risks foil starvation)
- Trap for CMYK-over-foil: 0.15 mm overlap on the foil edge
- Avoid: ultra-fine hairlines under 0.15 pt, isolated dots below 0.3 mm
Cold foil is a spot color in prepress — request a dedicated PANTONE spot channel named "COLDFOIL" in your artwork file, and the printer will map it to the adhesive plate.
Sustainability and recyclability
Modern cold foil systems are more sustainable than hot foil for three reasons:
- No heat energy — a typical inline cold foil unit draws ~30–40% less power than a hot foil finisher.
- Foil waste is recoverable — the peeled foil web (typically 88–95% of the raw foil consumed) is rewound and can be sent to specialist recyclers such as Foilex Recycling Scheme or downcycled into industrial fillers.
- Substrate recyclability — because cold foil adheres in thin discrete areas, foil-decorated paper and board typically remain recyclable under the 4evergreen Alliance recyclability protocol when foil coverage is below ~5% of surface area.
Frequently asked questions
Frequently asked questions
What is cold foil stamping in one sentence? +
Cold foil stamping is an inline printing process that bonds a thin layer of metallized polyester foil to a substrate using a UV-cured adhesive applied through a flexo or offset plate at room temperature — no heated die and no engraved tooling required.
Why is it called "cold" foil? +
It is called cold foil because, unlike traditional hot foil stamping, the process uses no heat to transfer the metallic layer. Bonding is achieved by a UV-curable adhesive activated with ultraviolet light, so the foil, adhesive, and substrate all remain at ambient temperature throughout the transfer.
Is cold foil stamping cheaper than hot foil? +
For runs above roughly 10,000–15,000 impressions, cold foil is typically 35–60% cheaper per unit than hot foil because it eliminates the engraved die, runs 3–6× faster, and integrates into the same press pass as CMYK printing. For runs under 3,000, hot foil or digital foil is usually more economical.
Can you print CMYK over cold foil? +
Yes. One of cold foil's key advantages is that the metallic area can be overprinted with CMYK inks in the same press pass, allowing a single silver foil to be transformed into gold, copper, rose, teal, or any custom metallic color — without a separate finishing operation.
What is the minimum text size for cold foil? +
Recommended minimums are 5 pt for sans-serif and 6 pt for serif typefaces, with a minimum line weight of 0.25 pt (0.09 mm). Below these limits, foil coverage becomes inconsistent and fine detail may drop out during the peel step.
What substrates work best with cold foil? +
Cold foil performs best on smooth, low-porosity substrates — coated paper (SBS, C1S, C2S ≥ 120 gsm), BOPP film, and PET film. Uncoated paper, kraft board without primer, and metallic substrates are not recommended because they either absorb the adhesive or prevent proper bonding.
Is cold foil recyclable? +
Cold-foil-decorated paper and board are generally recyclable under the 4evergreen Alliance protocol when foil coverage is below approximately 5% of surface area. The unused foil web peeled off during production (typically 88–95% of raw foil consumed) is also recoverable through specialist recycling schemes.
