Web Graphics Defaults
Manages color for content that will be published on the World
Wide Web.
When you choose a predefined configuration, the Color Settings dialog box updates to
display the specific color management settings associated with the configuration.
About working spaces
Among other options, predefined color management settings specify the color profiles to
be associated with the RGB, CMYK, and Grayscale color modes. The settings also specify
the color profile for spot colors in a document. Central to the color management workflow,
these profiles are known as
working spaces
. The working spaces specified by predefined
settings represent the color profiles that will produce the best color fidelity for several
common output conditions. For example, the U.S. Prepress Defaults setting uses a CMYK
working space that is designed to preserve color consistency under standard Specifica-
tions for Web Offset Publications (SWOP) press conditions.
A working space acts as the color profile for untagged documents and newly created
documents that use the associated color mode. For example, if Adobe RGB (1998) is the
current RGB working space, each new RGB document that you create will use colors within
the Adobe RGB (1998) color space. Working spaces also define the destination color space
of documents converted to RGB, CMYK, or Grayscale color mode.
About color management policies
When you specify a predefined color management setting, Photoshop sets up a color
management workflow that will be used as the standard for all documents and color data
that you open or import. For a newly created document, the color workflow operates
relatively seamlessly: the document uses the working space profile associated with its
color mode for creating and editing colors.
However, 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 has been created using different color management settings, or a
document that has been scanned and tagged with a scanner profile.
In either case, Photoshop must decide how to handle the color data in the document.
A
color management policy
looks for the color profile associated with an opened
document or imported color data, and compares the profile (or lack of profile) with the
current working space to make default color management decisions. If the profile is
missing or does not match the working space, Photoshop displays a message that
indicates the default action for the policy. In many cases you will also be provided with the
opportunity to choose another action. For detailed information on the color management
decisions associated with different policies, see
“Specifying color management policies”
