Decorative products created by lazing graphics and patterns directly on substrates with painted surfaces
A painted surface is processed by a laser beam to remove at least one layer of paint. The surface that is exposed may be the raw substrate material, e.g., wood or wood laminate, or may be another painted surface. The laser may engrave a pattern, e.g. a wood grain pattern.
1. A method comprising:
applying and moving a laser beam having a power level between 500 and 5,000 watts and a speed between 0.5 and 65 meters per second relative to a painted substrate comprising a substrate layer, a first layer of paint overlaying the substrate layer, and a second layer of paint overlaying the first layer of paint, wherein the first layer of paint has a first color and the second layer of paint has a second color different than the first color; and
etching the painted substrate with the laser beam to form a graphic, the laser beam fusing the first layer of paint and the second layer of paint together.
2. A method as in claim 1 , wherein the substrate layer comprises wood fiber.
3. A method as in claim 2 , wherein the graphic is a wood grain pattern.
4. A method as in claim 1 , wherein the substrate layer comprises at least one member selected form the group consisting of steel, metal and alloy.
5. A method as in claim 1 , wherein the substrate layer comprises at least one member selected from the group consisting of plastic, PVC, and urethane.
