We propose a design method that processes the surface of Urushi, a Japanese traditional coating material, with computer technology and ultraviolet (UV) light control. Urushi changes their physical condition by absorbing UV light energy. Our research introduces design method with this physical feature for digital fabrication. Our contribution is to realize imprinting method on urushi coated surface with computerdesigned pattern. We use two methods to control of the light. One method is laser method that uses laser and galvanomirror. The other one is mask method that uses a lamp and mask pattern. We introduce suitable material and procedure for these methods, and demonstrate the potential of them.
