UV security
Fibres, inks and hidden marks that appear only under an ultraviolet lamp.
Fluorescent inks are invisible in daylight and glow under 365 nm UV. We use rainbow multicolour compositions, hidden marks and microtext, as well as fibres and planchettes in paper.
UV features are the second level of verification at banks, borders and document issuing offices.
