A method for producing graphic signs on a covering material envisages providing a substrate (10) and depositing on said substrate (10) a particulate material (14) that is able to define the graphic sign. In a preferred way, the particulate material (14) is deposited on the substrate (10) in a substantially uniform way, and is then impressed (16) selectively (18) in the substrate (10) so that (20) where it is subjected to impression (16) the particulate material (14) is fixed to the substrate (10). Then the particulate material (14) is removed (22) from the areas where it is not fixed to the substrate (10). The particulate material is then anchored to the substrate (10) so that the particulate material (4) anchored to the substrate (10) defines the desired graphic sign. |
