Self Erasing Paper

This Paper Will Erase Itself in 24 Hours, ReUsable upto 100 Times



Have you ever printed out an e-mail message or meeting agenda, only to throw it out a few hours later? If Xerox researchers are to be believed, promiscuous printing happens all the time. Based on studies at their own office and elsewhere, the researchers claim that up to 40 percent of all documents printed in offices are discarded within a day.


The company has a solution: erasable paper. Hailed by Time magazine as one of the best inventions of 2007, Xerox has invented a new form of Self Erasable Paper Technology that would self erase anything printed on the surface of special type of paper within a time span of 24 hours, the paper can then be reused for upto 100 times. So you might ask what the use of this? well it can be used in offices, instead of trashing or recycling the paper, it can be used again and again for upto 100 times. This Reusable paper is environmentally safe, reduces paper waste and could also help in lowering overall paper costs.


How the technology works:


The paper is coated with a chemical that changes color when exposed to a certain wavelength of light but fades back to its original shade in 16 to 24 hours, making the paper reusable. The paper contains specially coded molecules that create a print after being exposed to ultraviolet light emitted from a thin bar in a printer. The molecule readjusts itself within 24 hours to its original form to delete the print, or heat can readjust the molecule instantly. Xerox developed the molecule. The ultraviolet bar itself is very small, so it can also be used in mobile printers.

Of course it doesn't last forever. Dirt happens. But a Xerox spokesman says the paper can survive about 50 passes through a printer.Erasable paper may save trees but not printers: Xerox research suggests you'll want to have a separate printer for disappearing documents. Send your document to the wrong printer, and you could turn your company's annual report into a daily report.—Dawn Stover
