The invention provides a method for conducting CD pattern corrosion machining and laser cutting on the surface of a base material to form a LOGO. The method comprises the first step of mask plate manufacturing, the second step of light resistance film coating and baking, the third step of exposure and baking, the fourth step of developing and baking, the fourth step of etching and the sixth step of laser cutting. The method is high in efficiency and precision and wide in application range. Due to the fact that the surface of the base material is polished, and CD patterns are provided with many convex blocks microcosmically, irradiation of light to the surface of the base material is equivalent to the fact that chromatic dispersion of many small prisms can occur, and different colors are presented. Due to the fact that the CD patterns are etched on the base material, the risk of falling cannot happen, and the colorful effect is more lasting.
