Dot peening is a laser marking process which presses a marker-stylus against the surface of the material. Color is then added to the depressions. Typically, dot peening is used to produce alphanumeric characters, bar codes, custom graphic and logos on hard or metal surfaces. Dot peen marking is an impact-marking technique that produces a series of closely-spaced dots which resemble a solid line. The workpiece must have sufficient hardness so that the material's memory does not return the surface to its original condition. Dot peen marking is suitable for metals in the range of 62 Rockwell, and can be used with plastics and hardwoods.
