It's worth noting the following when attaching profiles:
PostScript files can contain calibrated color information. However, they do not contain
•
ICC profiles. Instead, images that use device-independent colors (such as those tagged
with ICC profiles) are saved in a device-independent CIE color space in PostScript.
Images using device-dependent colors remain as they were. No color information is lost
in the resulting PostScript file.You can use the Color dialog box to attach new, and even
different, ICC profiles to the distilled PDF file.This action doesn't alter the colors, it just
calibrates them to different profiles.
When tagging for color management, Distiller attaches a separate profile for each color
•
space in a file. For example, a document might contain five images: one in Grayscale,
and two each in the RGB and CMYK color spaces. In this case, Distiller would attach a
separate ICC profile to calibrate the color for each color space, for a total of three
profiles.
Note: To ensure that the final printed output is the color you want, it is a good idea to
consult your printer or service bureau and specify color options based on their recommen-
dations.
Setting the Distiller Color job options
Whether you elect to use color management information in the PostScript file, use Distiller
CSFs, or define custom settings, you set all the color management information for Distiller
in the Color tab of the Job Options dialog box.
To set the Color job options:
1 Select an existing set of job options from the Job Options menu in the Acrobat Distiller
dialog box to use as a starting point.
2 Choose Settings > Job Options.
3 Click the Color tab.
4 Choose a value from the Settings File menu.This menu contains a list of color settings
that are also used in major graphics applications, such as Photoshop and Illustrator. For a
description of the color settings, see
setting you choose determines the other options available in this dialog box. For example,
if you choose anything other than None, all options other than those for Device-
Dependent Data are predefined and are grayed out.You can edit the Color Management
Policies and Working Spaces settings only if you select None for Settings File.
5 If you selected None from the Settings File menu, choose a color management policy
from the pop-up menu:
Leave Color Unchanged.This option leaves device-dependent colors unchanged and
•
preserves device-independent colors as the nearest possible equivalent in PDF. It is a
useful option for print shops that have calibrated all their devices, used that infor-
mation to specify color in the file, and are only outputting to those devices.

bility selected in the General job options, the Tag Everything for Color Management
option lets you embed an ICC profile when distilling files and calibrates color in the
images, making colors in the resulting PDF files device-independent. With Acrobat 3.0
compatibility selected, Convert Everything for Color Management does not embed ICC
profiles in the files. However, device-dependent color spaces in files (RGB, Grayscale,
