Hot foil stamping is a method often used to embellish and emboss premium print media. It’s used on things like letterhead and wedding invitations to add a touch of luxury. The operation is actually quite simple, where a custom die is heated, pressed into a heat transfer foil, and then transferred on to the print media.

Converting Film Camera to Digital the Hard Way
