Abstract (en)
The feature has a carrier substrate on which a continuous-tone image is printed. The continuous-tone image is transferred into a high-resolution bar element by a morphologic transition, which takes place in predetermined portions e.g. depth or interior, in the image. The bar element is mathematically defined by a guilloche function or a polygonal function. A carrier foil e.g. flexible plastic foils, is utilized as the carrier substrate and has a thickness of 5-700 micrometers preferably 12-50 micrometers.
