Wheeling, Illinois --- Micro Format, Inc. a specialty paper manufacturer and business forms distributor announced that patent number 5,636,874 has been issued for their Temperature Sensitive Security Document. This "pro-active" security feature incorporates the use of "temperature sensitive ink" printed on "at least a portion of one of the surfaces" to identify an original document. When touched or rubbed, the portion of the Temperature Sensitive Security Document on which the ink is printed, changes color, returning within moments to it's original color state.

This patent applies to checks, certificates, coupons, tickets and other "one-of-a-kind" valuable documents. Documents incorporating this unique color change capability, are impossible to accurately duplicate using a color copier or scanner.

Steve Singer, President of Micro Format, indicated that his patent application has been in process for many years. Now that the patent has been issued, he is currently investigating "partnering relationships" with companies interested in using his patented Color Change Document Security feature.

"When we first applied for the patent for our Temperature Sensitive Security Document invention" Said Singer, "Our focus was on developing unique business related products. The need for a way to easily identify an original document became apparent as low cost color copiers and color scanners entered the marketplace. Having had experience working with printed color change inks, we conceived the idea of combining temperature sensitive inks with security documents. Over the past five years, everyone has become aware of the need for protecting documents from forgery. This patented process can be used to protect Negotiable Documents including Checks, Tickets, Contracts, Coupons, Gift Certificates ... any valuable document.

The following abstract is from the documentation for United States Patent 5,636,874 .

Abstract

A single blank is provided with four removable sections which are sub-divided by lines of weakening and fold lines. The blank is foldable along a longitudinal line and transverse line to form the four sections into a four layer product. Upon removable from the blank, the four layer product may be manipulated to expose different sub-sections and, thus, provide different pictorial representations depending upon the imaging of the sub-sections. The sub-sections are imaged in a coordinated manner to produce different scenes.
