The recently launched NanogravureTM security element for banknotes has become possible by introducing XXI century nanotechnology methods into image origination. Owing to this unique methodology proprietary to Optaglio, NanogravureTM is a single-source technology, which is extremely counterfeit resistant and will remain so for the foreseeable future.
The NanogravureTM technology is non-holographic and is aimed to significantly enhance banknote security. It is a nanotechnology-based imaging method enabling to create a portrait or object-based feature with a highly unusual visual appearance, which will ensure reliable visual authentication by the public and experts alike, and also to incorporate a wide range of forensic features. NanogravureTM is optimised for poor lighting conditions, which makes it ideal for public recognition in everyday life, and is extremely resistant crumple and wear. NanogravureTM cannot be counterfeited using other imaging techniques available at this time.
The key to authenticating a NanogravureTM image is what we call “visual tactility” - a unique combination of visual impression and tactility, somewhat similar to the intaglio print in principle, but working in reverse. Whereas a fine-line apparently flat intaglio printing gives a “raised” feel to the touch, a NanogravureTM image appears mechanically engraved or embossed i.e. gives a visual impression of being raised above or sunk below the surface of the note, while it is completely flat to the touch. This simple and efficient authentication method is a result of a complex nanostructure that is assembled at ultra-high resolution using our proprietary methodologies. NanogravureTM is an example of how simplicity is achieved through extreme complexity.
NanogravureTM is available exclusively to Central Banks, banknote paper mills and banknote printers as an origination and/or as a finished component for application onto banknotes (in the form of hot-stamping foil stripe or registered patch).
