AgiLite™: A Novel OVD Security Feature for Document Protection

SECTAGO’s AgilLiteTM technology is based on an innovative method to create a novel type of diffractive origination. Its creation involves unique mastering equipment, proprietary materials and software. The OVD image derives from a large number of diffractive surface elements which are designed to sophistically interact: Upon illumination the image is synthesized from individually generated light points which are directed towards the viewer’s eye.

The image appears bright-white and is customisable within a high degree of freedom, including the representation of numbers, figures, logos, etc. By tilt or rotation of the device the displayed image shows continuous, coordinated motion at high agility, additionally exhibiting a distinct 3D-effect. Hence, it combines the mobility and optical depth of lens-supported security features with the thin diffractive optic of hologram-type devices.

The gratings are generated by a mask-less lithographic process with pitch values ranging from <300nm to >5,000nm. Parameter settings are highly variable: pitch, depth and vector angle of the gratings are individually chosen and matched to each other to create the unique optical properties of the feature. Despite its complex origination, manufacturing of this OVD feature has been proven to be cost competitive by means of either standard UV-casting or hot- embossing processes.

The basic concept of this new origination technology and a selection of AgilLiteTM examples will be presented. Distinguishing well from other diffractive security features, they are optically attractive, easy to communicate and difficult to counterfeit, altogether making them well suited for the protection of high security documents.

AgilLite®: A Novel Security Feature for High Security Documents

AgilLite® technology is based on an innovative method to create novel diffractive originations distinguishing from all other known DOVID features. It involves one-of-a-kind mastering equipment as well as proprietary materials and software.

The visible information is built on diffractive surface elements sophistically designed to compose an image which, upon illumination, is projected towards the observer. This image appears bright-white and is customizable within a high degree of freedom including the representation of numbers, figures, graphical elements etc. ("Symbols"). By tilt or rotation of the device the displayed Symbols reveal continuous, coordinated motion at high agility to the authenticator, additionally exhibiting a distinct 3D-effect. Hence, it combines the mobility and optical depth of lens-based (refractive) security features with the thin diffractive optic of hologram type devices.

Despite its outstanding optical characteristics, manufacture of this new DOVID has been demonstrated to be cost competitive: Starting from its origination master, pilot production has been successfully performed by means of either standard uv casting or hot embossing processes on roll-to-roll equipment. The paper applied AgilLite® foil passed standard PCR tests for banknote application.

A selection of examples based on AgilLite® origination technology will be presented. They are unique, optically attractive, easy to communicate and difficult to counterfeit, making them ideally suited for the protection of high security documents.
