You can change the default behavior to embed or not to embed profiles as you save a
document. Changing the default behavior, however, is recommended only for advanced
users who are very familiar with color management.
document. Changing the default behavior, however, is recommended only for advanced
users who are very familiar with color management.
To change the embedding behavior of a profile in a document:
1 Choose File > Save. Name the document, specify a file format, and click Save.
2 In the file format options dialog box that appears, select or deselect Embed ICC Profile.
3 Click OK to save the document.
Obtaining, installing, and updating color profiles
Precise, consistent color management requires accurate ICC-compliant profiles of all of
your color devices. For example, without an accurate scanner profile, a perfectly scanned
image may appear incorrect in another program, simply due to any difference in gamuts
between the scanner and the program displaying the image. This misleading represen-
tation may cause you to make unnecessary, time-wasting, and potentially damaging
“corrections” to an already satisfactory image. With an accurate profile, a program
importing the image can correct for any gamut differences and display a scan’s actual
colors.

Once you obtain accurate profiles, they will work with all applications that are compatible
with your color-management system. You can obtain profiles in the following ways, with

with your color-management system. You can obtain profiles in the following ways, with
the most precise methods listed first:
•
Generate profiles customized for your specific devices using professional profiling
equipment.
•
Check with your service provider. Some providers will use their equipment to create a
profile for your equipment.
•
Obtain a profile created by the manufacturer. Unfortunately, such profiles do not
account for individual variations that naturally occur among machines (even identical
models from the same manufacturer) or from age.
models from the same manufacturer) or from age.
•
Substitute an available profile that may be appropriate given information you have
about the device’s gamut. For example, many Mac OS scanners have been optimized
for an Apple RGB monitor gamut, so you might try using an Apple monitor profile for
these devices. Be sure to proof images created with the profile before using the profile
in production. This workaround is unlikely to produce results suitable for professionally
color-managed work.

Adding device profiles to the color management system
The Illustrator installer lets you choose from manufacturer-supplied device profiles for
some commonly used equipment. This is useful if you don’t have access to hardware-
based calibration tools. It is not possible for the installer to supply profiles for all devices.
If the installer did not install a profile for your device, create one or contact the device
manufacturer to obtain one.

To minimize confusion when working with profiles, delete any profiles for devices not
used by you or your workgroup.

In Mac OS, you can organize the ColorSync Profiles folder by creating additional
folders within it, or adding aliases to other folders.
