    Xerox creates infrared text technology
    Xerox Corp. said Thursday it will introduce a new, inexpensive technology to help thwart counterfeiters.
    new technology allows customers to print pages with variable text
    visible only under infrared light. Xerox says the technology could be
    used to authenticate tickets, coupons, certificates, license and other
    identification papers that have been profitable to forge.The specialty
    imaging font is printed with ordinary toner and can be produced on
    standard Xerox digital systems using regular paper.If a document with
    the special font is copied or altered, the text becomes distorted and
    illegible under infrared light.

    Xerox Technology Tricks Counterfeiters
    2007 Xerox 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® 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
    color systems work. Every color 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 color, like teal
    blue. But since each of the individual toner colors 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.”

    new technology is incorporated in Xerox’s FreeFlow 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,”
