Abstract
The invention relates to a security marking printed via intaglio process. The security marking includes multitone 2D intaglio patterns of intaglio modules containing encoded data according to specific encoding symbols. The decoding of the symbols, together with measured tone values for tiny shifts around their positions at decoding stage on a digital image of the intaglio patterns in correlation with the symbols, provides a robust and precise estimation of a register error between modules of distinct tones, thus allowing to easily detect any fake marking obtained via offset printing, even with a smartphone.
