ABSTRACT:
A method is provided for marking a molded hand grip such as a golf grip (100) with specialized information such as a personalized signature. The method utilizes a laser marking device (50) that is operative to provide an optical beam (8) having power and optical wave length characteristics effective to vaporize a continuous groove or trench and/or adjacently positioned dots in a target region ("R") on the hand grip to which beam (8) is exposed. The marked grip is then removed from device (50) and a selected colorant (16) such as paint or ink of desired color is then deposited in the marking that is preferably bondable to the desired extent to the material from which the hand grip is molded after which any excess colorant is then removed to provide the finished hand grip having the specialized information marked thereon.
