Method for marking references on a flat article and related system

A method for marking references on a flat article, comprising steps of:

• a) predisposing, on a detecting plane, a model provided with at least a through-opening, the model exhibiting a same peripheral profile as a flat article to be marked;
• b) detecting the peripheral profile of the model with respect to a reference system and storing the peripheral profile in a memory of a processing device;
• c) detecting a profile of the through-opening and the relative positioning with respect to a reference system;
• d) predisposing the flat article on a marking plane;
• e) detecting a peripheral profile of the flat article to be marked;
• f) replicating the peripheral profile of the model detected on the marking plane, in such a way as to superpose it on the peripheral profile of the flat article to be marked;
• g) replicating also the profile of the through-opening of the detected model on the marking plane, taking account of the relative positioning with respect to a reference system and taking account of the positioning of the peripheral profile of the model with respect to the peripheral profile of the flat article;
• h) contactless marking of at least a reference on the flat article at the profile of the through-opening which has been replicated.
