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...
