Foil stamping uses a metal die and foil film to apply a metallic or pigmented finish to specific areas of a printed piece. It is a separate pass from ink; the foil is pressed into the substrate with heat and pressure. It adds cost and is best for accent areas, not full coverage.
When foil makes sense
Foil works well for logos, borders, type, and small accent areas. It creates a premium look and stands out on matte or uncoated stock. Full-bleed foil or very large areas are possible but cost more and can have registration or coverage limits.
Process and cost
A die is made for the foil area; each color or finish may need a separate die. Setup cost is fixed per die; run cost depends on sheet count and foil type. Short runs absorb more setup per unit; long runs spread the cost.
Before you specify foil
• Confirm the substrate is suitable for foil (see foil-substrate-limitations).
• Keep foil areas defined; avoid hairline detail that may not stamp cleanly.
• Ask for die cost and run cost so you can budget.
Common mistake
Assuming foil is "just another color" and can go anywhere. Foil requires a die, compatible substrate, and correct file setup (knockouts, traps). Plan for it from the start.
