FluoroTrust technology is based on the formation of fluorescent microstructures in a polymer film upon exposure to arbitrarily structured light with a specific wavelength. These fluorescent entities can be used as labels for authentication, track-and-trace, and serialization purposes.
Key Advantages of FluoroTrust
- Labels can be made with sub-micrometer resolution.
- The microstructures are embedded in the polymer, making it difficult to remove the information.
- The fluorescence has a specific spectrum, which adds an extra level of security to the embedded information.
- The printing process does not emit ink aerosols or droplets, as the pattern is generated with a photoreduction process.
