The high-resolution security features, optical effects and sharpness are also retained during transfer, making the films suitable for processing security labels and security related materials, the company said. 
 
As with hot stamping foils, advast suisse also offers a range of existing generic designs for holographic cold foils. For individual, customer-specific implementations, both conventional hologram mastering as well as high-resolution Nanocrypt mastering are available.  
 
Nanocrypt is claimed to be one of the most secure and technologically advanced nano-optical imaging systems. With resolutions up to 640,000dpi, nano-structures and anti-counterfeiting security features can be achieved which cannot be reproduced by conventional mastering systems making the OVD designs unique, the company said.  
 
Cold foil application makes it possible to achieve holographic effects and security features for short runs. In comparison to the hot stamping process, initial costs for stamping dies and additional embossing are eliminated. Further cold foil stamping is said to not cause any deformation of the substrate – embossed counterfeit-proof security features such as nanotext and microtext remain visible and can be authenticated.
