Foil stamping is a mechanical process, not a printing one. A die is made in the shape of your artwork, heated, and pressed through a roll of foil onto the board. The heat and pressure release the foil layer from its carrier film and bond it to the surface, in exactly the shape of the die. What you get is a genuinely reflective surface that no ink can match.
How a foil job runs
- The foil artwork is supplied as its own layer, in solid black, positioned on the dieline.
- A stamping die is produced from that layer.
- The sheets are printed and, if required, laminated first.
- The die is heated and the sheets pass through the press, applying the foil.
- The sheets are then die cut, folded and glued as normal.
Types of foil worth knowing
| Foil | What it looks like | Note |
|---|---|---|
| Bright metallic | Mirror gold, silver, copper, rose | The most common choice, highest contrast on dark board |
| Matte metallic | Brushed, softer reflection | Reads more restrained, hides fingerprints better |
| Pigment foil | Flat colour with no metallic sheen | Useful for solid white or black on kraft or textured board |
| Holographic | Rainbow diffraction pattern | High impact, harder to keep on brand |
Design rules that keep foil sharp
- Avoid hairlines. Very thin strokes either fill in with foil spread or break up entirely.
- Keep small type simple. Serifs with fine hairlines are the first thing to close up at small sizes.
- Leave gaps between separate foil elements. Two shapes close together can bridge.
- Think about the surface underneath. Foil sits best on a smooth or laminated surface. Heavily textured board and some coatings resist adhesion, so flag your stock early.
- Large solid foil areas show every imperfection in the board beneath them. Small, deliberate foil usually looks more expensive than a fully foiled panel.
Foil, emboss and the combination die
Foil can be flat, or it can be combined with an emboss so the foiled area is also raised. That needs a combination die cut to do both jobs in one hit, which keeps the foil and the relief in perfect register. It costs more than flat foil and it is the most convincing premium detail available on a printed carton. Blind embossing, with no foil at all, is the quiet version of the same idea.
What it adds to a job
Foil adds a pass, and a pass adds time. Build that into your schedule rather than into your rush budget. The minimum is 100 boxes, pricing starts from about $0.48 per unit at bulk volumes and is confirmed on your written quote, and turnaround is quoted per product across three lanes: rush, which is expedited production plus air freight and carries a premium of roughly 7 to 25 percent depending on the job, standard on air, and cost saver on sea, from about 7 business days in production plus 2 to 5 days for delivery. Specialty finishes on imported constructions can run up to about 12 weeks.
Before you build the file, what bleed is in packaging artwork covers how the foil layer should sit on the dieline. For a construction that shows foil off well, see custom rigid gift boxes, or send your artwork with a quote request and we will tell you what the foil will do at that size.
