Light Printed Rewritable Paper

[Paper That Can Be Printed With Light And Reused 80 Times]

Researchers from Shandong University in China, the University of California, Riverside and Lawrence Berkeley National Laboratory recently published a study detailing the invention of light-printable, rewritable paper.

Their invention employs the color-changing chemistry of nanoparticles, which can be applied via a thin coating to a variety of surfaces – including conventional paper.

The technology works simply enough: a UV light printer zaps the paper everywhere except where the text is meant to be. The text then boldly stands out against the clear, light-zapped background.

The new light-printable paper if perfect for applications where printed information is only needed for a short time.

Yadong Yin, professor of chemistry at the University of California, Riverside explains

We believe the rewritable paper has many practical applications involving temporary information recording and reading, such as newspapers, magazines, posters, notepads, writing easels, product life indicators, oxygen sensors, and rewritable labels for various applications.
