    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.
