When Performing Color Adjustment and Color Verification
- When Color Adjustment is not performed: Perform Color Adjustment.
- When Color Adjustment is performed already (when a profile is created and registered): Perform Color Verification. However, perform Color Adjustment, and then perform Color Verification again, when the result of Color Verification is determined to be NG.
During color verification, the average/maximum delta E values in color deviation are evaluated using the standard and tolerance values of the colors that are specified in the selected print standard. Note that the color chart used in the evaluation is modified for use on the machine and does not guarantee conformance with various certification standards.

The color deviation and judgment result (OK/ NG) displayed in Post-judgment might differ from those when a different colorimeter is used.
