This equipment enables us to produce "raised printing". After the business cards come out of the press, the sheets of paper are fed through this machine which spreads a light dusting of powder over the wet ink. The machine then heats the powdered ink and expands, creating the raised texture. When it comes out at the other end, it is dry.
Thermography is primarily used for business cards, but can also be used for invitations and stationery. Impress your clients after you give them your business card. Notice how "interactive" your card is to touch.
