Issued on UN World Tuna Day in May, the new Solomon Island five-dollar banknote is the world’s first circulating note to feature SUSI Flip™, our advanced UV phosphorescent security feature.

SUSI-Flip™ combines high security with striking effects thanks to an innovative UV treatment.

A mono-colour design seen under daylight (image A) “switches” to a three-colour image under UV (image B). This effect is achieved by juxtaposing very fine lines of two complementary UV colours, giving the impression of a third colour.

“This element exploits the full potential of the SIMULTAN’s offset precision in same-side registration,” says Hervé Guillerey, head of banknote innovation & design services at KBA-NotaSys. “Due to its configuration and complexity, SUSI Flip™ is more advanced than any other offset UV feature on the market. It is virtually impossible to reproduce using commercially available technologies and thus very difficult to counterfeit. Furthermore, the feature is easy to recognise and understand for the public.”

According to the Central Bank of Solomon Islands, the new note promotes a strong sense of community and social cohesion by communicating important national issues. “We are also very proud to be the pioneer in using SUSI Flip™, which combines a very high security level with a strong visual impact,” explains Daniel Haridi, chief manager for currency, banking & payments.

SUSI Flip™ is compatible with all substrates and offers complete freedom in terms of its design and placement, while generating no additional operating costs on a SIMULTAN printing press.
