Colour security

A security printing solution addresses the growing global problem of product and document counterfeiting.

Developed by Colour Secure, the company's 'colour signatures' promise to extend sophisticated anti-counterfeiting protection to a far wider audience than previously possible, and are verified by a colour reading terminal employing a novel form of spectrometer designed by Cambridge Consultants.

Colour Secure's technology uses special security inks that create unique and discreet colour signatures that can be printed onto labels or documents using standard printing technology. These signatures can hold encrypted information such as product ID, to combat attempts at forgery. The colour signatures are virtually impossible to copy and cannot be read by any other commercially-available terminal. The printing can even be done using a conventional office printer and security inks.

Cambridge Consultants' role has been to help combine the low-cost security technique with a simple colour recognition capability that can accurately measure invisible-to-the-eye information embedded in the colour signatures.
