In-Depth Information
But not all RGB and CMYK gamuts are alike. Each monitor and printer model
differs, and so each displays a slightly different gamut. For example, one brand of
monitor may produce slightly brighter blues than another. The
color space
for a
device is defined by the gamut it can reproduce.
The color management system in Photoshop uses International Color Consortium
(ICC)-compliant color profiles to convert colors from one color space into another.
A color profile is a description of a device's color space, such as the CMYK color
space of a particular printer. You specify which profiles to use to accurately proof
and print your images. Once you've selected the profiles, Photoshop can embed
them into your image files, so that Photoshop and other applications can accur-
ately manage color for the image.
For information on embedding color profiles, see Photoshop Help.
Before you begin working with color management, you should calibrate your
monitor. If your monitor doesn't display colors accurately, color adjustments you
make based on the image you see on your monitor may not be accurate. For in-
formation about calibrating your monitor, see Photoshop Help.
Specifying color-management settings
In order to accurately preview your colors onscreen, you need to set up color man-
agement in Photoshop. Most of the color-management controls you need are in the
Color Settings dialog box.
By default, Photoshop is set up for RGB as part of a digital workflow. If you are
preparing artwork for print production, however, you'll want to change the set-
tings to be more appropriate for images that will be printed on paper rather than
displayed on a screen.
You'll create customized color settings.
