ABSTRACT:
The present invention is directed to a system for marking objects for their identification. The inventive system includes a laser that emits a select band of radiation and a coating system for application to an object or workpiece to be marked. The coating system is composed of two contrasting coats of paint, a topcoat and a basecoat, which have been coated sequentially on the workpiece. The topcoat, while still wet, can be ablated by the beam of said laser while the basecoat, while wet, dry or tacky, is refractory to the beam of said laser. The laser, thus, can generate alphanumeric and graphic characters (product identification indicia) on the workpiece by its beam being directed onto the coating system for ablating the topcoat to reveal the basecoat to generate the characters by dint of the visible contrast between the two coats of paint.
