Zero ink (Zink) printing technology does not use the printer ink for
printing; it uses special ink instead.This device was first introduced by a company called Zink. Zink's first generation of printers could produce only 2 by 3 inch colour photographs and the second generation which is yet to roll out can produce the prints of size of upto 10 by 15 cm.
How Zink works
The system involves the use of a special type of paper which has minute dye crystals embedded in it. The printer head melts these tiny ink particles by sending out minute heat pulses. Depending on the length of the heat pulse, the different colour ink crystals present at the different layers will melt and will blend together to produce the required colour combination.
Each square inch of the print contains 300 printheads and the technology produces a precisely crafted heat pulse to produce the required colour. Thus 200 million pulses of heat needed to make a 2- by 3-inch print.
The three colour layers are arranged in the descending order: Yellow, magenta, cyan. the highest melting point and the shortest pulse is for yellow, then followed by that of magenta and then that of Cyan
