Anti-Stokes Security Features

 

Security features printed using inks with anti-Stokes properties, often referred to as up-converting inks, are invisible to the naked eye and can only be visualised under high intensity IR illumination that causes them to emit a visible colour emission.

Used on a variety of high security documents including high denomination banknotes, travels documents and pharmaceutical labels, anti-Stokes security inks are manufactured using luminsecent materials containing rare-earth metals.

Anti-Stokes powders are also available for use in the development of latent fingerprints.
