The revolutionary AURORA™ feature uses high-security colour-switching ink pairs. When direct light catches the feature, the two distinct colours switch to appear to be in a similar tonal range, creating a striking visual effect.
STRONG COUNTERFEIT RESISTANCE
AURORA™ utilises an optical effect called angular metamerism in which an ink pair will appear as one colour at a certain angle of light, then a totally different colour at another angle of light. Two colour-switching ink pairs designed together, create enormous complexity for a would-be counterfeiter.
As a printed ink feature visible on both sides of the banknote, AURORA™ plays an integral role in a design that integrates both aesthetics and security. AURORA™ can be printed in a half window or full window and is designed into a single visual narrative with other security features.
