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.

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.

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 determine. It’s the semi-public security feature no one expects and yet everyone will remember.

Use Spectrum Fibres™ as un upgrade to an existing security paper without having to change your design. Add them to the pulp and make your paper unique!
