To investigate the relationship between colorimetric values of a CRT display and colored papers when their color appearances are matched in practical situations, color matching experiments were conducted under ldquo;The recommended condition for color matching between self-luminous displays and hard-copiesrdquo; that has been proposed by the Illuminating Engineering Institute of Japan.The experiments were performed under five CRT screen conditions: 1) CRT monitor shaded by a small hood, 2) shaded by a large hood, 3) without a hood, 4) without a hood but with a black border on the CRT bezel and 5) shaded by a large hood with a white surrounding. Conditions 1 to 4 are expected to cause different contrast effects, but Condition 5 is not.The results show that the colorimetric values of a color-matched CRT display and colored papers are not equal in practical situations, and that the disagreement is caused by the contrast effectsbe tween the CRT screen and its surroundings, and also by other effects. The contrast effect can be predicted from the luminance value of the CRT screen surroundings.These results suggest that the CRT screen surroundings be carefully considered for accurate cross-media color reproduction.
