KURZ Moves on With KINEGRAM DYNAMIC®

Foil and thin film technology company KURZ has been a pioneer in the use of diffractive optical anti-counterfeit features on banknotes since its earliest developments. Now, KURZ has made another step forward, with OVD Kinegram (OVDK), a member of the KURZ Group since 1999, in introducing its latest optical technology, KINEGRAM DYNAMIC®.

The introduction of KINEGRAM DYNAMIC technology is the next building block in KURZ’s modular banknote protection strategy as it introduces micro-lens based features into the anticounterfeit module.

Unlike some micro-fabrication techniques that rely on a regular array, KINEGRAM DYNAMIC has a structure where the lenses are arranged in a freeform array and the shape and size of the lens surface can be individually adapted to the customer’s requirements. The resulting properties of the array allow design control over the multiple colours, movement, depth, magnification, inversion and light & shade of image elements.

To help launch KINEGRAM DYNAMIC, KURZ ran a webinar on 16 February for a vetted audience of central bank officials and industry partners, during which Dr Harald Walter (Head of Micro & Nano Engineering at OVDK) confirmed that the novel technology is a micro-lens based optical feature that provides multi-coloured deep 3D dynamic movement effects, allowing limitless design integration. It can be applied in the normal patch or registered stripe form factors that you would expect on banknotes. Threads are likely to follow in a second phase of development.
