Title:
ブロンジング指標値算出方法、及びブロンジング指標値算出装置
Document Type and Number:
Japanese Patent JP5682759
Kind Code:
B2
Abstract:
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.
