Calibrating and Profiling Your Display
To color calibrate your display, you must use a third-party color management system.
Calibrating and profiling your display with a color management system is fairly easy.
Today, color management systems do most of the work for you. Color calibration
systems often come with an optical device that you place over the screen to read the
display’s output.
To calibrate and profile your display:
1 Install the software that came with your color management system.
2 Open the color calibration software application.
3 Attach the optical device to your display, and follow the instructions that came with
your color management system.
When the application has finished calibrating your display, it asks you to save the
custom ICC profile created during the calibration process. This profile is saved at Users/
username/Library/ColorSync/Profiles/. Now your display is calibrated.
If you have a second display, you can calibrate it as well.
