抄録
The light reflective images of natural Japanese lacquer paints applied on a board were analysed in addition to their colour and gloss measurements, in order to clarify the optical characteristics of the paint, which craftspeople can distinguish. The distribution of luminance on sample images was obtained at two angles under visible light irradiation and the envelope intensity curve was taken from the luminance histogram for black natural-lacquer-painted and chemically coated boards. There are no distinguishing differences in the spectroreflectance and gloss characteristics for the three kinds of black sample boards. It was found by the Gaussian curve fitting for the reflected light profile in the vicinity of the edge of reflected light image on the samples that the glossy natural-lacquer-painted sample shows the smallest area and standard deviation value of the reflected light profile. The results show that the glossy natural-lacquer-painted board reflects light most regularly and the diffusion of the light is smallest. Further, the area and standard deviation values for only the glossy natural-lacquer-painted sample decrease with an increase in the angle between the directions of the normal to the plane of the sample and the reflected sample image.
