Spectrum Fibres™

One fibre, six colours. Our newest multi-colour and multi-effect fibres fluoresce in the six main spectral colours of red, orange, yellow, green, blue and violet.

Security features must be counterfeit-proof, yet identifiable beyond any doubt. It is therefore so important for them to incorporate eye-catching colours to attract your attention.

Spectrum Fibres™ are completely invisible in normal light but under UV light, they fluoresce in the six main spectral colours along the length of the fibre in the same order.

Our new Spectrum Fibre™ combines the whole range of spectral colours making this fibre almost impossible to counterfeit. The unique and eye-catching ‘spectrum’ appearance makes it easy to describe and for the observer to identify.  

Your fibres will be unique to you and the colours chosen can be personalised and coordinated according to the colours on the flag of your country

These fibre properties and fibre size make it ideal for applications such as passports, banknotes and other Government documents
