Criteria for Color Verification
During color verification, the average and maximum delta E values in color deviation
are evaluated using the standard and the tolerance values specified by the selected
color space. The color chart used for verification is reprinted with the ICC profile
resulted after the color adjustment and does not guarantee conformance with various
verification standards.
