Thermochromic inks

Thermochromic inks change color due to a change in temperature. (Change is reversible.)

  • Cold (0°C, 5°C, 10°C, 15°C) and warm (20°C, 25°C, 27°C, 37°C) temperature types are colored below the temperature and change to colorless above the temperature.
  • For graphical or textile water-based applications.
  • Screen and flexographic printing.
