Zero ink printing or liNK in short is a technology that has been researched and developed by liNK Imaging. Pioneered by a group of scientists this awe inspiring. technology provides an easy and convenient alternative to bulky printers and. ink cartridges while maintaining high quality printing.

Mechanism of Zero ink printing

liNK uses a special paper with embedded dye crystals known as 'Amorphocromic' crystals which stimulates into different colors on heating. These crystals respond differently to heat impulses of varying duration and intensities, due to which they take on different colors.

This paper is typically made up of five layers, The first layer which is known as the 'Base layer' consists of an adhesive substance in which these crystals are placed. The second layer is known as the 'Cyan Imaging layer' which when affected low temperature releases a cyan dye that is formed into the image.

The third layer, which is the 'Magenta imaging layer' releases a magenta dye but only when heated at a medium temperature. The 'Yellow imaging layer' which is the fourth layer tends to release a yellow dye when heated at a high temperature. And last but not the least comes the 'Overcoat layer' which protects the image from any sort of damage once it has been printed.
