With all foiling and diecutting jobs, the stock must be bigger than the die. Provide accurate artwork for image placement. We need a combination negative to accurately place multiple foil images and foil images that register with printing. Foil stamping and embossing are low resolution processes. We cannot foil lines thinner than 1 point or keep reverses open finer than two points.
Coated stocks hold better foil detail.
Avoid embossing fine lines. Die wear out. Magnesium dies are delicate and easily damaged. They may not be suitable for some applications. Always store dies individually in protective wrappers or padded envelops.
