Guilloche and microtext
Intricate patterns of lines down to 20 µm and text legible only under a loupe. They cannot be reproduced by copiers.
Guilloche is a mathematically computed weave of fine lines. We generate the patterns programmatically, so every customer receives a unique rosette that cannot be reproduced by a scanner or printer.
Microtext is embedded in the pattern lines and field borders. When copied it collapses into a solid line — the first sign of forgery for an examiner.
