Leonhard Kurz, a supplier of security elements, has further developed its Trustseal optical authentication device, with the aim to make it more difficult to counterfeit.
“Anyone who rests on their laurels for too long allows counterfeiters time to imitate security features,” says Juergen Metzger, global sales manager for the product protection division at Kurz. “That’s why we are continuously developing our brand protection solutions. This enables us to stay at least one step ahead of the counterfeiters.”
Three new elements: Nanopic; Latent Contrust; and Overlapping Dynakey have been incorporated in the Trustseal OVD (Optically Variable Device). The Nanopic feature consists of images with a resolution, in part, of over 50,000dpi that can be combined with existing Trustseal features, and authenticated using a high powered magnifier.
Dynakey is a hidden element that becomes visible only when a special filter is placed over it. The new Overlapping Dynakey feature is superimposed on the main Trustseal motif, without obscuring the main visual design, and shows a striking movement effect when viewed through the filter.
Latent Contrust is a development of the earlier Contrust Trustseal element, a naked eye feature that exhibits a positive-negative light-dark contrast inversion when rotated by 90 degrees. The new Latent Contrust element is invisible when the OVD is viewed normally, and takes up no space from the main naked eye design. However the feature suddenly appears when the OVD is tilted to an extremely low viewing angle. When the design is turned by 90 degrees at this low angle, the contrast inversion is seen as a secondary effect.
Kurz will be present at drupa 2008 in hall 3, on stand 3C46.
