Abstract (en)
The present invention relates to a method for the manufacture a carbonizable polymeric substrate having a tactile relief marking with an emboss effect, in particular a data carrier substrate for documents with security features, the method comprising securing the carbonizable polymeric substrate of step b) by applying to the substrate a marking in the form of a relief with an emboss effect, by spot irradiation of a carbonizable polymer substrate by means of a computer-controlled RGB laser, the beam of which modifies the carbonizable polymer substrates at least in a part of the area, preferably over the entire area, the markings being obtained in the form of a relief with an emboss effect are obtained by creating punctual protrusions.
