Color management
Last updated 10/11/2011
If you open a document embedded with a color profile that doesn’t match the working space profile, the application
uses a color management policy to determine how to handle the color data. In most cases, the default policy is to
preserve the embedded profile.

Working space options
Select the Color Management category of the Preferences dialog box.
To view a description of any profile, select the profile and then position the pointer over the profile name. The
description appears at the bottom of the dialog box.
RGB Determines the RGB color space of the application. In general, it’s best to choose Adobe RGB or sRGB, rather
than the profile for a specific device (such as a monitor profile).
sRGB is recommended when you prepare images for the web, because it defines the color space of the standard
monitor used to view images on the web. sRGB is also a good choice when you work with images from consumer-level
digital cameras, because most of these cameras use sRGB as their default color space.
Adobe RGB is recommended when you prepare documents for print, because Adobe RGB’s gamut includes some
printable colors (cyans and blues in particular) that can’t be defined using sRGB. Adobe RGB is also a good choice
when working with images from professional-level digital cameras, because most of these cameras use Adobe RGB as
their default color space.
CMYK Determines the CMYK color space of the application. All CMYK working spaces are device-dependent,
meaning that they are based on actual ink and paper combinations. The CMYK working spaces Adobe supplies are
based on standard commercial print conditions.
Grayscale Determines the grayscale color space of the application.
Note: You can use the color space in an embedded output intent instead of a document color space for viewing and
printing. For more information on output intents, see Acrobat Help.
Adobe applications ship with a standard set of working space profiles that have been recommended and tested by
Adobe Systems for most color management workflows. By default, only these profiles appear in the working space
menus.
About missing and mismatched color profiles
For a newly created document, the color workflow usually operates seamlessly: Unless specified otherwise, the
document uses the working space profile associated with its color mode for creating and editing colors.
However, some existing documents may not use the working space profile that you have specified, and some existing
documents may not be color-managed. It is common to encounter the following exceptions to your color-managed
workflow:
• You might open a document or import color data (for example, by copying and pasting or dragging and dropping)
from a document that is not tagged with a profile. This is often the case when you open a document created in an
application that either does not support color management or has color management turned off.
• You might open a document or import color data from a document that is tagged with a profile different from the
current working space. This may be the case when you open a document that was created using different color
management settings, or scanned and tagged with a scanner profile.
