Producing Consistent Color (Photoshop)
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 approximately 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.
Also, be sure to use only one calibration utility to
display your profile; using multiple utilities can
result in incorrect color.

versus characterizing a monitor," "About
monitor calibration settings," "Guidelines for
creating an ICC monitor profile," and "Calibrating
with Adobe Gamma" in online Help.
