The marking mechanism were considered again, by pressing four kinds of fiber textures on two kinds of plates for automobile coating films. And the following results were obtained. 1. Fiber texture marks was the depression of the coating top layer. 2. The marks which resemble closely to those in traffic accidents could be formed on the following conditions. (1)Contacting time for fiber with the plate was 0.005〜0.01 sec. (2)Pressing vertical load for fiber to the films were 3.6〜9.1 MPa. (3)Friction coefficient between fiber and coating films was ca. 0.3〜0.5. (4)Sliding length for fiber on the films was ca. 0.018〜0.063 m. 3. The marks were influenced by the top layer of automobile coating films, fabric construction of cloth and another conditions. For example, metallic coating films which contains the top clear layer were printed more easily than the solid ones.
