varifeye ColourChange Patch: Easy, Flexible, and Secure

Same technology, different size: varifeye ColourChange Patch is a brilliant solution for maximum design freedom, security, and attraction. The small foil motifs (“patches”) can be individually shaped and placed on banknotes. An astonishing front and back side color change from gold to blue in reflection and transmission views ensures clear and instant recognition.

Room for additional features on banknotes is often scarce. Therefore, size, shape, and location of the varifeye ColourChange Patch and its LaserCut or Filigram window are highly flexible and can be customized to suit the holistic banknote design. Through the customized integration into the overall layout and substrate, varifeye ColourChange Patch provides new opportunities for connecting eye-catching images on the front with contrasting shapes and effects on the reverse. The combination of thin-film and micro-mirror technologies ensures a color-intensive and convincing color change from gold to blue in reflection and transmission views. As the ambient light is almost entirely reflected, the effects are easily recognizable – even in low-light conditions.

Unlike most other foil elements, the Patch allows for the integration of additional high-tech design elements on the foil. This makes it possible to synchronize various optical effects within the banknote design. Registered application ensures uniform positioning of the feature on the banknote – thus allowing recognition of the full feature area from the bottom to the top and even on the reverse of the banknote. The application is on one side only. Proven sheet pile stability and processability reduces the need for process adaptation.
