Thermography
Thermography produces raised printing similar in appearance to engraving but using a different process and is more economical as no dies are involved. In thermography, a special resin powder is applied to the ink printed on the paper. The printed piece is heated and the powder and ink mixture dries to form a raised effect on the paper.
Thermography is often used in place of the more expensive engraving process to produce wedding invitations, business cards, and letterhead. It is economical, a faster process, no drying time, and any ink color can be used. You can add a clear thermo coating to create special effects. Thermography is not laser printer compatible and will not hold fine detail. Screens are not recommended in the use of thermography.
