Thermography (raised-letter printing) is a printing process that produces a look that is similar to copperplate engraving. Thermography is fast becoming a popular choice for invitations and announcements because of its ability to enhance the printed text and overall stationery quality. Quite often, thermography appears even more raised than some engraved printing.

Immediately after printing, the (still wet) ink is dusted with a powder resin. The powder is then removed, so that it remains only on the inked areas. The printed piece then passes under heaters, which melts the resin and fuses it to the ink - producing a "raised" image or text!
