Thermography

Raised, glossy ink—the business-card classic.

1306

Wet ink is dusted with thermographic resin powder, then heat-fused to swell into a raised, glossy surface mimicking engraving.

Sprinkle resin powder on wet ink, then heat it. The powder melts and puffs up into raised, glossy text.

  • Cheap way to fake the look of engraving for business cards.
  • Powder only sticks to wet ink, so the rest brushes off.
  • Heat is what makes it puff and shine.

History

Developed in the early 20th century as a low-cost alternative to copperplate engraving. Standard for wedding stationery and corporate cards through the 1990s, still used widely today.
