Four color process—Four color printing works best for photos or designs with four or more colors.
PMS printing—PMS printing is best for non-photographic designs or those using three colors or less.
Foil stamping—Metallic foils are highly reflective, while non-metallic colors have the same smooth texture with less reflectivity.
Embossing—Embossing raises parts of the paper stock for visible texture. Long-fibered or textured stocks achieve the most dramatic effect.
Debossing—Debossing creates a recessed area in your paper stock. It also works best on long-fibered or textured stocks.
