XEROX INVENTS REUSABLE PAPER & USES UV-LIGHT AS INK
Palo
Alto Research Centre (PARC) which is a subsidiary of Xerox Inc has
developed a type of paper that, combined with a special printer, can
print documents that erase themselves after a day so that the paper can
be reused.According to Xerox almost 25 percent of all documents can be
recycled the same day they are printed, and that 44.5 percent are
intended only for a single viewing. Using the new printer and paper for
one-shot documents like daily menus, work summaries and office memos
could vastly reduce paper and energy use, the company said.”Think of
the Google map you printed to get here,” PARC Area Manager Eric Shrader
said at a product demonstration. “Thirty years ago, we said the future
was paperless.””Despite our reliance on computers to share and process
information, there is still a strong dependence on the printed page for
reading and absorbing content,” said Paul Smith, manager of Xerox’s new
materials design and synthesis lab.

The new paper is coated with
a chemical that turns dark upon exposure to ultraviolet (UV) radiation.
In order to create a document, the printer simply bombards the paper
with UV radiation in the appropriate places.While the “ink” will
eventually fade on its own, after 16 to 24 hours, the printer can also
be used to erase a page and print something new.Tests by Xerox found
that if it was not torn or crumpled, a single piece of paper could be
put through the print-and-erase cycle hundreds of times.The erasable
paper and ink are available in a variety of colors. Xerox expects to
take the new product commercial within the next few years.

Robert
Spinrad, 77, a computer designer who carried out pioneering work in
scientific automation at Brookhaven National Laboratory and who later
was director of Xerox’s Palo Alto Research Center, died of Lou Gehrig’s
disease on Wednesday in Palo Alto, Calif. Trained in electrical
engineering before computer science was a widely taught discipline,
Spinrad built his own computer from discarded telephone switching
equipment while he was a student at Columbia.
