Foil stamping is somewhat similar to letterpress, in that the color is applied to paper with pressure using a metal die. The foil (not ink) leaves a shiny, luxurious impression in both the look and feel of your invitations. Foil Stamping is labor intensive and therefore it is more expensive than other printing methods but its worth every penny!
Letterpress is a time consuming and artful printing process that has grown in popularity, especially the deeper, debosed impression that people want and love. The process uses polymer plates, custom mixed inks, and a printing press. Every color is printed individually so its important if budget is a concern to limit your colors to one or two. Letterpress is a time and skill heavy process and therefore is not cheap.
Thermography is a specialized process that combines offset printing ink with a powdered resin which is baked so that the resin rises to give the ink a raised, textured effect. Thermography, is a cost-effective alternative to achieve a raised effect similar to engraving and embossing.
