AVOIDING VOID PANTOGRAPH DRIVERS
– can be diffractive optical variable image features (found in holograms, kinegrams) or interference image structures (found in credit cards, drivers license, some banknotes). – impossible to reproduce or copied by photocopiers, scanners or digital image-capture equipment and have become a cornerstone for document security applications – changes in appearances (color or information) when viewed at different angles, when device is rotated, or when the color temperature or dominant wavelength is changed
