Stabilizing Colors (Color Calibration Execution Guide Settings)
It is important to carry out color calibration because color tones change as a printhead ages and the environment
changes.
This printer has a function that notifies when it is recommended to execute color calibration. This prevents forgetting to
carry out color calibration and allows you to continuously reduce variations in color tones.
In the CCMC color management utility, Advisability of executing color calibration is displayed as a progress bar.
This allows you to manage color efficiently because you can visually check roughly how long until color calibration is
executed next.
For a detailed explanation, see the following.
