Fluorescent, Semi-Transparent Window Boosts Banknote Security

In the July edition of Holography & Optical Technology News®, we spotlighted Q&T Hi-Tech Polymer’s POLYSECURE SHIELD – the polymer banknote substrate with an embedded OVD. In this issue, we continue our coverage of banknote anticounterfeiting innovations with a look at the CBRI’s new approach to window security features, blending fluorescent effects with fine-pattern transparency directly in paper substrates.
