In foil blocking, what is the role of the brass die?

• A. It heats the foil to transfer it.
• B. It applies pressure to transfer foil with heat.
• C. It provides pressure to transfer the foil without heat.
• D. It cuts the foil into desired shapes.

Answer: (C)

In foil blocking, the brass die is responsible for applying the pattern onto the surface through pressure alone, without using heat. This is the cold-foil/foil-blocking approach: the foil carries an adhesive or the surface is receptive to foil, and when the die and press come together, the foil is pressed into place in the exact shape of the engraved design. The brass die is chosen because it can hold a precise, fine impression and withstand repeated use while delivering clean, sharp results. This method relies on the force of contact to transfer the foil, not on heat, which is why it differs from hot foil stamping where heat is essential.
