6 . . Use color management when printing and saving files.
Keeping the appearance of colors consistent across all of the devices in your workflow is the goal of color management.
Leave color management options enabled when printing documents, saving files, and preparing files for online
viewing. (See “Printing with color management” on page 392 and “Color-managing documents for online viewing” on
page 390.)
Synchronize color settings across Adobe applications
If you use Adobe Creative Suite, you can use Adobe Bridge to automatically synchronize color settings across
applications. This synchronization ensures that colors look the same in all color-managed Adobe applications.
If color settings are not synchronized, a warning message appears at the top of the Color Settings dialog box in each
application. Adobe recommends that you synchronize color settings before you work with new or existing documents.
1 Open Bridge.
To open Bridge from a Creative Suite application, choose File > Browse. To open Bridge directly, either choose Adobe
Bridge from the Start menu (Windows) or double-click the Adobe Bridge icon (M a cOS).
2 Choose Edit > Creative Suite Color Settings.
3 Select a color setting from the list, and click Apply.
If none of the default settings meet your requirements, select Show Expanded List Of Color Setting Files to view
additional settings. To install a custom settings file, such as a file you received from a print service provider, click Show
Saved Color Settings Files.
Set up color management
1 Select the Color Management category of the Preferences dialog box.
2 Select a color setting from the Settings menu, and click OK.
The setting you select determines which color working spaces are used by the application, what happens when you
open and import files with embedded profiles, and how the color management system converts colors. To view a
description of a setting, select the setting and then position the pointer over the setting name. The description appears
at the bottom of the dialog box.
Note: Acrobat color settings are a subset of those used in InDesign, Illustrator, and Photoshop.
In certain situations, such as if your service provider supplies you with a custom output profile, you may need to customize
specific options in the Color Settings dialog box. However, customizing is recommended for advanced users only.
Note: If you work with more than one Adobe application, it is highly recommended that you synchronize your color
settings across applications. (See “Synchronize color settings across Adobe applications” on pag e389.)
Managing process and spot colors
When color management is on, any color you apply or create within a color-managed Adobe application automatically
uses a color profile that corresponds to the document. If you switch color modes, the color management system uses
the appropriate profiles to translate the color to the new color model you choose.
Keep in mind the following guidelines for working with process and spot colors:
• Choose a CMYK working space that matches your CMYK output conditions to ensure that you can accurately
define and view process colors.

• Select colors from a color library. Adobe applications come with several standard color libraries, which you can load
using the Swatches panel menu.
• Use Lab values (the default) to display predefined spot colors (such as colors from the TOYO, PANTONE, DIC,
and HKS libraries) and convert these colors to process colors. Using Lab values provides the greatest accuracy and
guarantees the consistent display of colors across Creative Suite applications.
Note: Color-managing spot colors provides a close approximation of a spot color on your proofing device and monitor.
However, it is difficult to exactly reproduce a spot color on a monitor or proofing device because many spot color inks exist
outside the gamuts of many of those devices.
Color-managing imported images
Using a safe CMYK workflow
A safe CMYK workflow ensures that CMYK color numbers are preserved all the way to the final output device, as
opposed to being converted by your color management system. This workflow is beneficial if you want to
incrementally adopt color management practices. For example, you can use CMYK profiles to soft-proof and hard-
proof documents without the possibility of unintended color conversions occurring during final output.
You can override safe CMYK settings when you print a document or save it to Adobe PDF. However, doing so may
cause colors to be reseparated. For example, pure CMYK black objects may be reseparated as rich black. For more
information on color management options for printing and saving PDFs, search in Help.
Preparing imported graphics for color management
Use the following general guidelines to prepare graphics for being color-managed in Adobe applications:
• Embed an ICC-compliant profile when you save the file. The file formats that support embedded profiles are JPEG,
PDF, PSD (Photoshop), AI (Illustrator), INDD (InDesign), Photoshop EPS, Large Document Format, and TIFF.
• If you plan to reuse a color graphic for multiple final output devices or media, such as for print, video, and the web,
prepare the graphic using RGB or Lab colors whenever possible. If you must save in a color model other than RGB
or Lab, keep a copy of the original graphic. RGB and Lab color models represent larger color gamuts than most
output devices can reproduce, retaining as much color information as possible before being translated to a smaller
output color gamut.

Color-managing documents for online viewing
Color-managing documents for online viewing
Color management for online viewing is very different from color management for printed media. With printed
media, you have far more control over the appearance of the final document. With online media, your document will
appear on a wide range of possibly uncalibrated monitors and video display systems, significantly limiting your control
over color consistency.

When you color-manage documents that will be viewed exclusively on the web, Adobe recommends that you use the
sRGB color space. sRGB is the default working space for most Adobe color settings, but you can verify that sRGB is
selected in the Color Management preferences. With the working space set to sRGB, any RGB graphics you create will
use sRGB as the color space.
When working with images that have an embedded color profile other than sRGB, you should convert the image’s
colors to sRGB before you save the image for use on the web. If you want the application to automatically convert the
colors to sRGB when you open the image, select Convert To Working Space as the RGB color management policy.
(Make sure that your RGB working space is set to sRGB.)

Color-managing PDFs for online viewing
When you export PDFs, you can choose to embed profiles. PDFs with embedded profiles reproduce color consistently
in Acrobat 4.0 or later running under a properly configured color management system.
Keep in mind that embedding color profiles increases the size of PDFs. RGB profiles are usually small (around 3 KB);
however, CMYK profiles can range from 0.5 to 2MB.

Color-managing HTML documents for online viewing
Many web browsers do not support color management. Of the browsers that do support color management, not all
instances can be considered color-managed because they may be running on systems where the monitors are not
calibrated. In addition, few web pages contain images with embedded profiles. If you manage a highly controlled
environment, such as the intranet of a design studio, you may be able to achieve some degree of HTML color
management for images by equipping everyone with a browser that supports color management and calibrating all
monitors.
You can approximate how colors will look on uncalibrated monitors by using the sRGB color space. However, because
color reproduction varies among uncalibrated monitors, you still won’t be able to anticipate the true range of potential
display variations.
Proofing colors
About soft-proofing colors
In a traditional publishing workflow, you print a hard proof of your document to preview how its colors will look when
reproduced on a specific output device. In a color-managed workflow, you can use the precision of color profiles to
soft-proof your document directly on the monitor. You can display an on-screen preview of how your document’s
colors will look when reproduced on a particular output device.
Keep in mind that the reliability of the soft proof depends upon the quality of your monitor, the profiles of your
monitor and output devices, and the ambient lighting conditions of your work environment.

Note: A soft proof alone doesn’t let you preview how overprinting will look when printed on an offset press. If you work
with documents that contain overprinting, turn on Overprint Preview to accurately preview overprints in a soft proof. In
Acrobat, the Overprint Preview option is automatically applied.

Soft-proof colors
1 Do one of the following, depending on your version of Acrobat:
• (Acrobat 9) Choose Advanced > Print Production > Output Preview.
• (Acrobat X) Choose Tools > Print Production > Output Preview.
2 Choose the color profile of a specific output device from the Simulation Profile menu.
3 Choose a soft-proof option:
Simulate Black Ink
Simulates the dark gray you really get instead of a solid black on many printers, according to the
proof profile. Not all profiles support this option.
Simulate Paper Color
Simulates the dingy white of real paper, according to the proof profile. Not all profiles support
this option.
Color-managing documents when printing
Printing with color management
Color management options for printing let you specify how you want Adobe applications to handle the outgoing
image data so the printer will print colors consistent with what you see on your monitor. Your options for printing
color-managed documents depend on the Adobe application you use, as well as the output device you select. In
general, you have the following choices for handling colors during printing:
• Let the printer determine colors.
• Let the application determine colors.
Letting the printer determine colors when printing
In this workflow, the application does no color conversion, but sends all necessary conversion information to the
output device. This method is especially convenient when printing to inkjet photo printers, because each combination
of paper type, printing resolution, and additional printing parameters (such as high-speed printing) requires a
different profile. Most new inkjet photo printers come with fairly accurate profiles built into the driver, so letting the
printer select the right profile saves time and alleviates mistakes. This method is also recommended if you are not
familiar with color management.

If you choose this method, it is very important that you set up printing options and turn on color management in your
printer driver. Search Help for additional instructions.
If you select a PostScript printer, you can take advantage of PostScript color management. PostScript color
management makes it possible to perform color composite output or color separations at the raster image processor
(RIP)—a process called in-RIP separations—so that a program need only specify parameters for separation and let the
device calculate the final color values. PostScript color-managed output workflows require an output device that
supports PostScript color management using PostScript Level 2 version 2017 or later, or PostScript Language Level 3.
Letting the application determine colors when printing
In this workflow, the application does all the color conversion, generating color data specific to one output device. The
application uses the assigned color profiles to convert colors to the output device’s gamut, and sends the resulting
values to the output device. The accuracy of this method depends on the accuracy of the printer profile you select. Use
this workflow when you have custom ICC profiles for each specific printer, ink, and paper combination.
If you choose this option, it is very important that you disable color management in your printer driver. Letting the
application and the printer driver simultaneously manage colors during printing results in unpredictable color. Search
Help for additional instructions.
Obtaining custom profiles for desktop printers
If the output profiles that come with your printer don’t produce satisfactory results, you obtain custom profiles in the
following ways:
• Purchase a profile for your type of printer and paper. This is usually the easiest and least expensive method.
• Purchase a profile for your specific printer and paper. This method involves printing a profiling target on your
printer and paper, and providing that target to a company that will create a specific profile. This is more expensive
than purchasing a standard profile, but can provide better results because it compensates for any manufacturing
variations in printers.
• Create your own profile using a scanner-based system. This method involves using profile-creation software and
your own flatbed scanner to scan the profiling target. It can provide excellent results for matte surface papers, but
not glossy papers. (Glossy papers tend to have fluorescent brighteners in them that look different to a scanner than
they do in room light.)
• Create your own profile using a hardware profile-creation tool. This method is expensive but can provide the best
results. A good hardware tool can create an accurate profile even with glossy papers.
• Tweak a profile created using one of the previous methods with profile-editing software. This software can be
complex to use, but it lets you correct problems with a profile or simply adjust a profile to produce results more to
your taste.

Color-managing PDFs for printing
When you create Adobe PDFs for commercial printing, you can specify how color information is represented. The
easiest way to do this is using a PDF/X standard; however, you can also specify color-handling options manually in the
Output section of the PDF dialog box. For more information about PDF/X and how to create PDFs, search Help.

In general, you have the following choices for handling colors when creating PDFs:
• (PDF/X-3) Does not convert colors. Use this method when creating a document that will be printed or displayed
on various or unknown devices. When you select a PDF/X-3 standard, color profiles are automatically embedded
in the PDF.
• (PDF/X-1a) Converts all colors to the destination CMYK color space. Use this method if you want to create a press-
ready file that does not require any further color conversions. When you select a PDF/X-1a standard, no profiles
are embedded in the PDF.
Note: All spot color information is preserved during color conversion; only the process color equivalents convert to the
designated color space.

Working with color profiles
About 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 between the scanner and the program displaying the image. This misleading
representation 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 device
differences and display a scan’s actual colors.
A color management system uses the following kinds of profiles:
Monitor profiles
Describe how the monitor is currently reproducing color. This is the first profile you should create
because viewing color accurately on your monitor allows for critical color decisions in the design process. If what you
see on your monitor is not representative of the actual colors in your document, you will not be able to maintain color
consistency.
Input device profiles
Describe what colors an input device is capable of capturing or scanning. If your digital camera
offers a choice of profiles, Adobe recommends that you select Adobe RGB. Otherwise, use sRGB (which is the default
for most cameras). Advanced users may also consider using different profiles for different light sources. For scanner
profiles, some photographers create separate profiles for each type or brand of film scanned on a scanner.
Output device profiles
Describe the color space of output devices like desktop printers or a printing press. The color
management system uses output device profiles to properly map the colors in a document to the colors within the
gamut of an output device’s color space. The output profile should also take into consideration specific printing
conditions, such as the type of paper and ink. For example, glossy paper is capable of displaying a different range of
colors than matte paper.
Most printer drivers come with built-in color profiles. It’s a good idea to try these profiles before you invest in custom
profiles.
Document profiles
Define the specific RGB or CMYK color space of a document. By assigning, or tagging, a document
with a profile, the application provides a definition of actual color appearances in the document. For example, R=127,
G=12, B=107 is just a set of numbers that different devices will display differently. But when tagged with the Adobe
RGB color space, these numbers specify an actual color or wavelength of light—in this case, a specific color of purple.
