[Exact Color]
Overview
Carry out calibration using Exact Color.
The normal calibration adjusts the gradation output density for each single color (CMYK) while the Exact Color calibration adjusts the mixed colors (color with 2 or 3 colors mixed or gray balance), enhancing the color reproduction accuracy.
Tips
- A colorimeter is required to carry out [Execute Wizard of Exact Color]. For details about the colorimeter settings, refer to [Settings].
