Abstract:
1. A method for marking a manufactured article with a desired marking, the method comprising: applying an infusion dye to a dye pad shaped to correspond to the desired marking, applying an activation solution to the infusion dye, thereby forming an infusion dye mixture; placing the contact surface of the dye pad in contact with the discrete area of the outer surface of the manufactured article with the projection and the recess mated with each other; leaving the dye pad in contact with the outer surface of the manufactured article under room temperature and pressure, for a duration sufficient to allow the infusion dye mixture to open a polymeric structure of a material of the outer surface and to allow the infusion dye to penetrate the outer surface and form the desired marking within a substrate of the article; and removing the dye pad from the outer surface.
