Hot foil stamping

Example

A winery orders 3,000 labels for a new range. The wine name is stamped in matt gold, the rest prints in two colours on a textured stock. A metal die is cut from the vector of that name — paid for once and kept for the years after. The press heats it to somewhere around 100–150 °C, presses the foil ribbon against the paper, and the foil stays only where the die lands. Foil spreads under that pressure, so thin strokes are strengthened to come out solid and tight gaps inside letters are opened up so they do not fill; anything under 0.3 mm does not stamp reliably. The next vintage needs a new plate for the year only — the gold die stays as it is.

Why it matters for a business

Foil is visible across a room and obvious in the hand, which is why it turns up where products are chosen off a shelf or given as gifts: wine and spirits, cosmetics, boxes, invitations. It also works as a price signal — a foiled pack reads as a more expensive product without a word being written. The cost comes from three places: the die, the extra pass through the press, and the material used up in make-ready. So foil is a decision about one or two accents, not about a whole page. On plastics and laminated surfaces it needs a different foil grade, so the material has to be named up front.

What to ask

• What is the smallest detail the die will hold, and will the thin parts of the type survive?
• Which foil — gloss, matt, coloured, holographic — and is there a sample on our own stock?
• Who makes and stores the die, and does it carry over to the next run?
• Can it be combined with relief in a single pass, and what does that do to the schedule?
• How does the foil behave when folded, laminated, or in contact with moisture or grease?
