چکیده
The main goal of this study is determination the effect of GCR (gray component replacement) levels on colorimetric characteristics of color proof. To determine the effect of GCR levels on colors of color proofs, a comparison of 2D and 3D color gamuts depending on GCR level have been performed. In addition to obtain better assessment of the effect of GCR levels on color gamut were calculate volumes of 3D color gamuts and 2D surface areas. In order to determine the effect of GCR on colorimetric characteristics is performed colorimetric evaluation, expressed as color difference ΔEab.

The colorimetric error depends on the spectrophotometric inaccuracy. In this paper, a new method is introduced for determining the relationship between spectrophotometric error and colorimetric inaccuracy. The error propagation in colorimetric parameter calculation is evaluated using a linear relation between variance of reflectance spectra and CIE tristimulus values. This linear formula ca...
