A Journey Through the Design of Structural Colour on DOVIDs

At the Security Designers Forum 2026 held in Istanbul, Laurence Launay, Graphic Studio Manager at IN Groupe, presented 'A Journey Through the Design of Structural Colours on DOVIDs: Bridging Aesthetics and High-Tech Security'. Her presentation explored how structural colours are changing the way designers approach DOVIDs. A brief excerpt for readers is provided here.

At the heart of the approach is a clear distinction between security and attractiveness. The primary function of the DOVID is to provide a robust security effect that is easy to identify and explain, while remaining difficult to counterfeit. The design challenge is then to integrate this complex technology into a clear and coherent visual narrative. This is where structural colours offer a different approach to conventional security design.
