The method of applying a marking to a substrate comprises coating the general surface of the substrate, including the precise surface to be occupied by said marking, with a liquid substance which hardens and binds itself to the substrate, when subjected to a predetermined type of electromagnetic radiation; exposing the precise surface of the coated substance to be occupied by said marking to said predetermined type of electromagnetic radiation to cause said coated substance to harden and to bind itself to the substrate; and removing the portions of said coated substance not exposed to said electromagnetic radiation. |
