Scots uni’s new printing method ‘does not fade’

A new form of high-resolution “printing” which could be developed for anti-counterfeiting measures in banknotes has been discovered by scientists.

The nanoscale printing breakthrough could also have implications for data storage and digital imaging. Engineers from the University of Glasgow have developed“nano scale plasm onic” colour filters that display different colours depending on the orientation of the light which hits it.

This new technique allows the “printing” of two entirely different, but exceptionally detailed, fullcolour images

Lecturer Dr Alasdair Clark said: “There are a lot of potential applications. It’s ideal for long-term data archival due to its ultra-high resolution, and because the colours won’t fade.”
