non-profiled Windows scanner, try substituting the sRGB color space. Be sure to proof
images created with the profile before using the profile in production.
Adding device profiles to the color management system
You can add color profiles to your system so that they appear as choices in the Color
Settings dialog box. To minimize confusion when working with profiles, delete any profiles
for devices not used by you or your workgroup. Once you have added a profile to the
recommended location on your system, you may need to load it or restart Photoshop so
that the profile appears in the Color Settings dialog box.
Note:
In Mac OS, you can organize the ColorSync Profiles folder by creating additional
folders within it, or adding aliases to other folders. However, nested folders may cause
conflicts with some applications, such as Adobe PressReady.
To add profiles to your system:
Copy profiles to one of the following recommended locations:
•
(Windows 2000) WinNT/System/Spool/Drivers/Color.
•
(Windows NT) WinNT/System32/Color.
•
(Windows 98) Windows/System/Color.
•
(Mac OS 9.x) System Folder/ColorSync Profiles.
•
(Mac OS X) Users/CurrentUser/Library/ColorSync.
Note:
If you use ColorSync 2.5 but have used earlier versions, some profiles may still be
stored in the System Folder/Preferences/ColorSync
™
Profiles folder on your hard disk.
For compatibility 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. Using an ICC monitor profile helps you eliminate any color cast in your
monitor, make your monitor grays as neutral as possible, and standardize image display
across different monitors.
On Windows, you can use the Adobe Gamma software (installed with Photoshop) to
create a monitor profile. On Mac OS, you can use the Apple calibration utility to create a
monitor profile. In addition, there are hardware-based utilities that you can use to create a
monitor profile. Be sure to use only one calibration utility to display your profile; using
multiple utilities can result in incorrect color.
