Magic Printer Ink Developed In South Korea
South Korean researchers have developed a 'magic' printer ink, which they claim can produce full-colour pages in just a second.
M-Ink is made up of nanoparticles, a liquid for salvation and resin, and was developed by engineers at Seoul National University, New Scientist reports.
The magnetic nanoparticles, which measure between 100 and 200 nanometres across, form structures in a chain form when they come under an external magnet.
In turn, these structures reflect light and colour which people can see clearly.
Lead researcher Sunghoon Kwon explained that the ink can print off pages with colour from any part of the spectrum as it is based on the interaction of light rather than pigments.
"We first set the magnet to tune colour to red and then shine UV for 0.1 seconds [to fix the red areas of the image] and then change to blue, for 0.1 seconds again, then green," he told the publication.
"You can pattern A4-size full-colour prints within a second."
