We revisit the classical color shift for security threads by engaging the viewer with aesthetically pleasing color change effects, which can be combined with eye-catching movements to increase the complexity against counterfeiters.
COSMIC stands for a metallic color shift within the security thread that creates a further barrier to the counterfeiter, as well as an obvious invitation to the banknote user to inspect the note more closely. The technology offers a large variety of switching color shades, and can easily be combined with striking optical security effects such as KINEGRAM® FLUX Effect.
Our diffractive security threads are able to complement the principal colors of each individual banknote design or to match a surface-applied security feature for visual cross-referencing. It takes only a flick of the wrist to check the moving and color shifting security thread. 3D images, microtext, nanotext, and also magnetic, IR, UV, taggant-based or other covert and machine-readable features can be included. Partial demetallization in a customized pattern can add an additional layer of complexity.
