VTT Double / Triple Latent Image
The overlapping of two or three images with a predefined scrambling of the involved structures creates a visual shift between all images. Each of the images can hence be seen from different angles with a clear shift. The complexity of the manufacturing starting of with the generation of the graphical integration of the individual images gives an exceptional level of fraud resistance while visual inspection is quick and efficient. The application range is not limited to the use of specific materials which clearly adds to the flexibility of this secure element.
The combination with other elements such as e.g. VTT ODI will further complicate the fraudulent replication of the document.
