German ink manufacturer Hubergroup has unveiled a new and unique security ink called mouveGSI. Developed by its Berlin-based security ink subsidiary Gleitsmann Security Inks (GSI), the daylight-clear ink appears under UV light in three different, moving colors.
This new safety device shows color impressions that permanently change from red to green to orange or yellow when exposed to simple UV light.
To create this "traffic light" effect with a single ink, GSI worked for a year with the German manufacturer of luminescent materials, special chemicals and pigments Leuchtstoffwerk Breitungen (LWB). The GSI movement ink can be applied by gravure and screen printing without the need for material modifications.
The ink mouveGSI (which comes from movable UV element) "cannot be imitated with commercially available printing inks or films, especially because counterfeiters do not have access to the special pigments used", says GSI. "This feature is attractive not only for banknotes, but also for any security printing, such as tax stamps and sovereign identity documents."
A banknote has already been issued with this secure printing ink. "We are honored and very proud that the National Bank of Cambodia has chosen to incorporate mouveGSI into its prestigious commemorative banknote. With the application of mouveGSI on a banknote only five months after the launch of this unique feature, I am confident that we will see this innovative ink on other banknotes very soon." said Ulrich Walter, Managing Director of GSI.
