A collaboration between the Xerox Research Centre of Canada and the Palo Alto Research Center has made a real break-through with a type of paper that can be used over and over again.


Scientist Paul Smith at Xerox has invented a way to embed paper with a material that changes colour when exposed to light and is projected onto it by an inkless printer. The text disappears in 24 hours, so the sheet can be reused. It is estimated that as many as two out of every five pages printed in the office are for what can be called “daily” use, like e-mails, web pages and reference materials that have been printed for a single viewing.

Although still in a preliminary state, Xerox has filed for patents on the technology, which it calls “erasable paper.” It is currently part of a laboratory project that focuses on the concept of future dynamic documents.
