Zink Imaging has developed the world’s first inkless printer. It uses special paper that is made of “micro-thin layers containing three types of colour-forming dye crystals – yellow on top, magenta in the middle and cyan on the bottom.” Best of all, you’ll only have to wait 30-seconds for a picture to print. Expect to shell out $200 for this device when it’s released. One more picture after the jump.

To bring out the correct colour at each pixel, the temperature and exposure to the heater element is precisely controlled. The crystals in the top yellow layer require the highest temperature and shortest time to melt and become coloured; the magenta middle layer a lower temperature and longer time; and the bottom cyan layer the lowest temperatures and longest exposure time
