Process for the synchronised embossing of a extensible printed film (F) or of a laminate product (LM) comprising an extensible printed film, comprising at least the steps of: pre-heating the film; possible coupling of the pre-heated film with a substrate, passage of the film or of the laminate between an engraved embossing cylinder (201), and a pressing counter-cylinder (202), in which the extensible film is subjected to a controlled elongation (”L), in the longitudinal direction only, during the pre-heating step, during which the film is in a thermoplastic state, and said controlled elongation is such as to synchronise the decoration printed on the film with the position of the embossing cylinder. |
