| 摘要 | Calculating a difference between a hue angle of a colorimetric value of a printed object with respect to diffuse reflection and the hue angle of a colorimetric value of the printed object with respect to specular reflection, calculating the difference between a standard chroma with respect to an observational light source and the chroma of the colorimetric value of the printed object with respect to specular reflection under the observational light source, and calculating a bronzing index value on the basis of a value obtained by multiplying the calculated difference of the hue angles by the calculated difference of the chromas. | ||

| 主权项 | 1. A bronzing index value calculation method, comprising: calculating a difference between a hue angle of a colorimetric value of a printed object with respect to diffuse reflection and a hue angle of a colorimetric value of the printed object with respect to specular reflection; calculating a difference between a standard chroma with respect to an observational light source and a chroma of a colorimetric value of the printed object with respect to specular reflection under the observational light source; and calculating a bronzing index value on the basis of a value obtained by multiplying the calculated difference of the hue angles by the calculated difference of the chromas. | ||
