Abstract

Many samples with various color and gloss grades were measured by the spectrophotometer with integrating sphere, of which light trap size was variable. Samples include white plaques, ceramic tiles, paint panels, ink-jet printings, textiles and metal surfaces. For these samples, lightness and chromaticness change with light trap size, which is relate to the elimination of surface reflection, was examined. In case of color measurement, using integrating sphere, colorimetric values are affected by the light trap size, when gloss grade of sample is different.
