Rather than using metallic ink, you can create a very attractive effect with foil stamping. Gold foil is one of the most popular choices, however, it is not the only one. Silver and an assortment of colored metallic foils - along with special effect foils - are also available.
Similar to embossing, a die is created with a shape such as your logo or text, and is used to stamp the foil onto the paper. The size and complexity of the design can have a large effect on the cost of the die, as well as on the amount of foil used.
