Remove colorful background patterns on your monitor desktop. Busy or bright patterns
•
surrounding a document interfere with accurate color perception. Set your desktop to
display neutral grays only, using RGB values of 128. For more information, see the
documentation for your operating system.
If your monitor has digital controls for choosing the white point of your monitor from a
•
range of preset values, set those controls before starting the profiling utility. 6500 K is a
good white point for most uses; 5000 K is the common standard for U.S. prepress
providers.
Monitor performance changes and declines over time; recharacterize your monitor

every month or so. If you find it difficult or impossible to calibrate your monitor to a
standard, it may be too old and faded.
Calibrating with Adobe Gamma (Windows)
The ICC profile you get using Adobe Gamma uses the calibration settings to describe how
your monitor reproduces color.
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. Adobe Gamma's ability to calibrate settings depends on the video
card and video driver software. In such cases, some calibration options documented here
may not be available.
To use Adobe Gamma:
1 Start Adobe Gamma, located in the Control Panels folder or in the Program Files/
Common Files /Adobe/Calibration folder on your hard drive.
2 Do one of the following:
To use a version of the utility that will guide you through each step, select Step by Step,
•
and click OK. This version is recommended if you're inexperienced. If you choose this
option, follow the instructions described in the utility. Start from the default profile for
your monitor if available, and enter a unique description name for the profile. When
you are finished with Adobe Gamma, save the profile using the same description name.
(If you do not have a default profile, contact your monitor manufacturer for appropriate
phosphor specifications.)
To use a compact version of the utility with all the controls in one place, select Control
•
Panel, and click OK. This version is recommended if you have experience creating color
profiles.
At any time while working in the Adobe Gamma control panel, you can click the
Wizard button to switch to the wizard for instructions that guide you through the
same settings as in the control panel, one option at a time.
Saving and loading working space profiles
If none of the working space options in the Color Settings dialog box accurately describe
the color space of your particular output or display device, you can create a custom RGB,
CMYK, Grayscale, or Spot working space profile. Saving your custom profile ensures that
you can reuse it and share it with other users and other Adobe applications that use the
Color Settings dialog box.
