To add profiles to your system:
Do one of the following:
In Windows NT or 2000, copy profiles into the WinNT\System32\Color folder.
In Windows 98, copy profiles into the Windows\System\Color folder.
In Mac OS, copy profiles into the ColorSync Profiles folder in the System Folder 
(ColorSync 2.5 or later).
Note: If you use ColorSync 2.5 but have used earlier versions, some profiles may still be 
stored in System Folder/Preferences/ColorSync
 Profiles on your hard disk. For compati-
bility with ColorSync 2.5 or later, store profiles in the ColorSync Profiles folder in the System 
Folder.
Updating profiles
The color reproduction characteristics of a color device change as it ages, so recalibrate 
devices periodically and generate updated profiles. Profiles should be good for approxi-
mately a month depending on the device. Some monitors automatically compensate for 
phosphor aging.
Also, recalibrate a device when you change any of the factors that affect calibration. For 
example, recalibrate your monitor when you change the room lighting or the monitor 
brightness setting.
Creating an ICC monitor profile
Your monitor will display color more reliably if you use color management and accurate 
ICC profiles. The Adobe Gamma utility, which is automatically installed into your Control 
Panels folder, lets you calibrate and characterize your monitor to a standard and then save 
the settings as an ICC-compliant profile available to any program that uses your color 
management system. This calibration helps you eliminate any color cast in your monitor, 
make your monitor grays as neutral as possible, and standardize image display across 
different monitors.
Although Adobe Gamma is an effective calibration and profiling utility, hardware-based 
utilities are more precise. If you have a hardware-based utility that can generate an ICC-
compliant profile, you should use that instead of Adobe Gamma. 
Depending on your workflow scenario, an ICC monitor profile can be either a source 
profile, a destination profile, or both. 
Note: Adobe Gamma can characterize, but not calibrate, monitors used with Windows NT. 
In addition, the ICC profile you create with Adobe Gamma can be used as the system-level 
profile in Windows NT. Its ability to calibrate settings in Windows 98 depends on the video 
card and video driver software. In such cases, some calibration options documented here 
may not be available.
