In the paper ‘Structural Colours – Powerful & Self-explaining Design Elements’, Eduard Miloglyadov from OVD Kinegram (OVDK) told the story of his team’s work to make colours without using inks. The structural colours they create cover the whole visible spectrum and can be made a part of a transparent security feature as well as being observable in reflection on metal layers. The motivation for the research is not only to remove the reliance on inks but to create distinctive security features that are perfectly integrated with the design, without the need for mechanical registration.
