5.2.4.2 Adjusting Method of the Colorimetric Calibration
When color measurement is performed at the same place as the repair work
site, calibration is batch-processed. When color measurement is performed at
a place different from the repair work site, calibration is performed by separate
processes. The following illustrates the overall workflow.
