User Guide
Loading a separation table overrides any options
in the CMYK Setup dialog boxes. To use the
dialog box settings again, you must choose File >
Color Settings > CMYK Setup, and select Built-in
or ICC.
Managing ICC profiles in files
To manage color effectively across systems and
applications, it is important to embed (or tag) ICC
profiles into files. The ICC profiles then indicate
the correct color space for the file. When another
ICC-aware application opens a properly tagged
image file, that application knows what if any color
conversions are required.
The Profile Setup dialog box lets you specify how
Photoshop uses ICC profiles when opening and
saving files. This controls what color spaces are
assumed when you exchange files between appli-
cations and devices.
The default settings for Profile Setup are designed
to properly tag files in other applications and to
correctly convert files from Photoshop 4.0 and
earlier, which may have been created using a
different color space than in Photoshop 5. As a
result, entering Profile Setup information is
optional, particularly if you left the Profile Setup
dialog box at its default settings.
Note: When opening files, you may see a status bar
indicating that Photoshop is performing this
conversion. This conversion generally happens the
first time you open a file that is tagged with a
different ICC profile.
The following information can help you in speci-
fying Profile Setup options:
•
Embedding profiles increases the file size.
•
Embedding profiles provides color consistency
when a file is opened in another application or on
another system.
•
The Embed Profiles option affects how files are
saved.
•
Assumed Profiles and Profile Mismatch
handling options affect how files are opened.
•
File formats that support embedding include
EPS, JPEG, PCT, PDF (only for RGB and Grayscale
images), PSD, and TIFF.
•
Some applications require you to choose which
profile to associate with a file when opening the
file. To create an ICC profile for your RGB or
CMYK settings, see the instructions about loading
settings in “Entering RGB setup information” on
page 84 and “Using color separation tables” on
page 98.
To specify how Photoshop should interact with ICC
profiles:
1 Choose File > Color Settings > Profile Setup.
2 For Embed Profiles, select the types of files into
which you want to embed ICC profiles: RGB,
CMYK, Grayscale, Lab, or none at all. ICC profiles
will then be embedded when you save those types
of files.
Note: Deselecting the Embed Profiles option marks
the file as intentionally untagged, which disables the
assumed profile feature when the file is reopened.
This will prevent the file from being converted each
time you open it.
