Our Technology Product range consists of a palette of embedded, banknote security features.

OPTICALLY VARIABLE AND OTHER DEMETALLISED SECURITY THREADS

The use of demetallization in banknotes was pioneered by CRANE CURRENCY and now it can be found in most of the currency circulating world-wide. Demetallization is a fundamental element of many optical security materials, offering the general public immediate and simple validation without the use of any special tools. These security elements can be further enhanced through the addition of machine-readable characteristics. COMET™ The COMET (COded MEtallic) security thread embodies advanced counterfeit deterrence along with easy public and machine-recognition. COMET is based on the interplay between micro and macro demetallized elements where the micro elements contribute to a machine readable encoding scheme.   Public validation is simple, based on the macro elements, and can be authenticated in the same way as a watermark, with layers of added fine resolution detail seen under simple magnification.  The COMET security thread provides a solid foundation for building even higher levels of security and layered protection. DURAMET™ The DURAMET security thread is a wide windowed (3mm+) optically variable thread, incorporating enhanced durability characteristics. Using a layered security thread structure, it combines demetallization and lamination to encapsulate and protect the metal layer. DURAMET’s resistance to degradation is achieved through precise edge demetallization and periodic demetallization breaks, leaving the metal impervious, even to the strongest chemicals and mechanical wear. The striking optical effect is preserved throughout the entire life-cycle of the banknote. SWITCH™ SWITCH is a windowed diffractive security thread upon which two unique and easily recognizable diffractive elements are replicated. As the viewing angle is changed, a distinct switch between the two images is seen. Behind the SWITCH image, a diffractive background adds security and complexity, while enhancing the brilliance and overall aesthetics of the thread. SECURATEXT™ SECURATEXT is a demetallization technique that improves both the legibility and security of demetallized optically variable security threads. To create clearly visible lettering, the text is constructed from fine lines rather than traditional ‘clear text’. The full width of the thread can be used to convey a message in transmitted light without compromising the reflected light diffraction effects. SECURATEXT fine line demetallisation cannot be simulated by metallic ink or foil-transfer counterfeiting techniques.   info@cranecurrency.com
