Guidelines for creating an ICC monitor profile
The following guidelines can help you create an accurate monitor profile.
Keep your monitor's user guide handy while using a monitor calibration utility.
Calibrate your monitor regularly, using an ICC-compliant calibration utility; your
•
monitor's colors will shift over time.
If you have the Mac OS Gamma control panel (included with Adobe Photoshop 4.0 and
•
earlier) or the Monitor Setup utility (included with PageMaker 6.0) for Windows, remove
it; it is obsolete. Use the latest Adobe Gamma utility instead.
Make sure that your monitor has been on for at least half an hour. This gives it sufficient
•
time to warm up, for a more accurate color reading.
Make sure that your monitor displays thousands of colors or more.
•
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, refer to the
manual for your operating system.
If your monitor has digital controls for choosing the white point from a range of preset
•
values, set those controls before starting the calibration tool. Later, in the calibration
utility, you'll set the white point to match your monitor's current setting. Be sure to set
the digital controls before you start the calibration utility. If you set them after you
begin the calibration process in the utility, you'll need to begin the process again.
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
The ICC profile you get by using Adobe Gamma uses calibration settings to describe how
your monitor reproduces color. For more information on using Adobe Gamma, see the
technical guides in the Support area of adobe.com.
To use Adobe Gamma:
1 In Windows, double-click Adobe Gamma, located in the Control Panel (Start >
Settings > Control Panel).
Note: If a recent version of Adobe Gamma exists on your Mac OS system, you can start it in
the Apple menu. Choose Control Panels > Adobe Gamma.
2 Do one of the following:
To use a version of the utility that guides 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.
