Xerox technology tricks counterfeiters; personalized information on printed page is only visible under infrared light

    -   The News: Xerox scientists can print variable text visible only under
        infrared light. It's a smart, low-cost way to authenticate
        information and make documents more secure.

    -   The Context: Because security printing technologies have been
        expensive, their use has been restricted to applications where
        documents have very high value or where the cost can be spread over
        long run lengths.

    -   Why It Matters: The cost-effective technology can be used to thwart
        counterfeiters of tickets, coupons, certificates, licenses and other
        documents that have been profitable to forge.

    GRENOBLE, France, Oct. 4 /CNW/ - Xerox Corporation (NYSE:   XRX) today
introduced a new security technology that prints variable text that can't be
read under normal light, but can be read when exposed to infrared light. The
technology can be used to authenticate tickets, coupons, certificates,
licenses, identification papers and other high-value documents.
    InfraredMark Specialty Imaging Font does not require special ink, but is
printed with ordinary toner, the "dry ink" that forms xerographic images. It
can be produced on standard Xerox digital systems using standard papers. In
addition, if the document is copied or altered, the infrared text will become
substantially distorted under infrared light and therefore illegible.
    InfraredMark technology complements the company's existing specialty
imaging effects, such as MicroText marks and Glossmark(R) text, which provide
a cost-effective way to make documents more secure. Developed by scientists in
the Xerox Innovation Group, this research aligns with Xerox's goal of
developing smarter documents to make information-based work easier, more
efficient and more effective.
    According to Raja Bala, a principal scientist in the Xerox Research
Center Webster (N.Y.) and a co-inventor of the process, protecting sensitive
documents from unauthorized duplication or alteration is an ongoing challenge.
Traditional security printing is costly and reserved for documents of very
high value, such as passports, and/or very long run lengths, such as currency.
However, digital printing and specialty imaging effects make security printing
easy and affordable for run lengths of one to many.
    The new technology takes advantage of the way Xerox's xerographic colour
systems work. Every colour is made by mixing toner of four hues: cyan,
magenta, yellow and black, known by the initials CMYK.
    "There are multiple ways to mix these toners to create a single colour,
like teal blue. But since each of the individual toner colours reacts
differently to infrared (IR) light, some combinations are detectable under
infrared light and others are not," Bala said. "Xerox uses that effect to
create infrared text that is invisible to the human eye, but visible to an
infrared camera."
    "Another way to describe the process," Bala continued, "is that we can
develop a pair of cyan, magenta, yellow and black toner mixtures, one with
very little infrared absorption and the other with a lot of infrared
absorption. They will appear very similar to the eye under normal light, but
very different under IR light. If one CMYK mixture is used as the background,
and the other mixture as the text, then the result is a text message that is
invisible or at least illegible under normal light, and easily detectable
under IR light."
    The new technology is incorporated in Xerox's FreeFlow(R) Variable
Information Suite 6.0, which was announced in September. The software
streamlines the process of producing customized documents, and its specialty
fonts can be used to help thwart counterfeiting. With variable printing, these
security features can be personalized for each document, making it easier to
authenticate and reducing the incentive for forgery.
    Xerox researchers have worked for a number of years to develop
authentication technologies that help make documents more secure. In addition
to the InfraredMark technology, specialty imaging technologies include
MicroText, which prints text smaller than 1 point size; Glossmark text, which
prints text visible when the paper is tilted; FluorescentMark, which prints
text visible only under ultraviolet light; and Correlation Mark text, which
prints text visible only when a "key" overlay is superimposed.
    "These specialty imaging technologies offer new, inexpensive ways for our
customers to produce fraud-sensitive applications such as security badges,
tickets, coupons, invitations, and more through multiple, individualized,
linked and layered options," said Deborah Cantabene, vice president, workflow
marketing, Xerox Corporation.
