LCN Heat-Sensitive Postcards


Using thermo-sensitive black ink, Lin Chia Ning has fashioned a dynamic postcards set which the black varnish color fades at body temperature. Whenever the black ink part of the postcard is near to body temperature or heat, an image is produced. It is a dynamic, eye-catching, attention-grabbing and memorable way of sending your love to your friends or family. The amazing interactive element of this simple idea is both playful and intelligent.


How They Work?

The ink or dye is coloured when at room temperature and its high opacity hides anything printed on the layer below. But when heat is applied, either by the human hand or some other means - an increase in ambient temperature maybe, or the introduction of a warm liquid to a container - the dye becomes translucent, revealing the message, image, patterns or colours below.
