By using a PVC (polyvinyl chloride) sheet with micro-embossed lines, it was attempted to imitate the complicated gloss of wood figure which is generated from the three dimensional grain inclination. The results of the measurements of light reflection showed that the micro-embossed surface had extreme anisotropy of light reflection. This suggests that the change of direction of the embossed lines can be used for imitating the anisotropy of gloss figures of wood.
As the examples of application of the micro-embossed lines, the glosses of wavy figure of Japanese horse chestnut and bird's eye figures of maple were imitated. The former was well imitated by using the micro-embossed lines of combined sine curves of different wave lengths. The latter was also skillfully imitated by using embossed lines with three different directions which were determined by three photos of a wood sample taken from three different directions of lighting.
