Open a document.
Click the View menu, point to Proof
Setup, and then click Custom.
Click the Rendering Intent list
arrow, and then select from the
following options:
◆ Perceptual. Preserves the
natural colors of an image, as
viewed by the human eye,
sometimes at the expense of the
true color values. Good for
photographic images.
◆ Saturation. Produces vivid
colors in an image, without
paying attention to the original
color values of the image. Good
for business graphics, and
charts where you want the
colors to pop.
◆ Relative Colorimetric. Shifts the
color space of the document to
that of the maximum highlight
values of the destination. Useful
for photographic images, and
preserves more of the original
color than Perceptual.

◆ Absolute Colorimetric. Clips any
colors in the destination image
that do not fall into the color
gamut of the destination. Use to
proof images sent to devices
such as 4-color presses.
Click OK.

Rendering Intents define how the selected color profile is converted
from one color space into another. When you choose a rendering intent
you are specifying how the colors should be displayed, even at the
expense of the original gamut (range of colors) within the active docu-
ment. The rendering intent you choose depends on which colors are
critical in an image and on your preference of what the overall color
appearance of an image should be. Many times the intent of the
image's color gamut is different than how the original image was shot.

In the language of the print world, a soft proof is viewed on a monitor,
and a hard proof (sometimes referred to as a match print) is viewed on a

piece of paper, typically printed on a device such as an inkjet or laser
printer, that is less expensive than producing a hard proof from a print-
ing press. In the last few years, many inkjet printers now have the reso-
lution necessary to produce inexpensive prints that can be used as hard
proofs, which previously had to be printed on high-end printing presses,
or expensive high-resolution laser printers. A hard proof gives you
something you can hold in your hands, and is not only useful for viewing
colors, but even evaluating the layout. Since a monitor typically displays
a document at a different size than your printed document dimensions,
you now have an exact size to match to your final document and review
before going ahead with the final printing. When you select a printer in
the Preview Print dialog box, Photoshop automatically lists the profiles
installed for that printer at the top of the profile list (New!). If a printer
specific profile is available, Photoshop automatically selects it (New!)
for the best results, however you can change it as desired.

432 Chapter 18
Colors in an image will often look different when you view them using
different monitors. They may also look very different when printed on
your desktop printer or when printed on a professional printing press. If
your work in Photoshop requires you to produce consistent color
across different devices, managing color should be an essential part of
your workflow. Photoshop gives you a group of predefined color man-
agement systems, which are designed to help you produce consistent
color. These management systems are recognized by other Adobe
products, and by most professional printing services. In most cases, the
predefined sets are all you will need to manage color workflow or, as
you become more adept at managing color, they can be used as a basis
for creating your own customized sets. The power of color manage-
ment lies in its ability to produce consistent colors with a system that
reconciles differences between the color spaces of each device.

necessary to open a document).
Click the Edit menu, and then click
Color Settings.
Click the Settings list arrow, and
then select from the available

customized set (requires a
good knowledge of color
management and color theory).
◆ Monitor Color. For creating
content for video and onscreen
presentations.
◆ North America General

creating consistent workflow
with Adobe applications used
in North America.

Create your own customized color
sets using the following options:
◆ Working Spaces: Defines the
working color profiles for each
color model. Working Spaces
can be used for images that
were not previously color-
managed, or for newly created
color-managed documents.
◆ Color Management Policies:
Defines how the colors in a
specific color model are
managed. You can choose to
embed or convert the selected
profile, or to ignore it.
◆ Conversion Options: Defines
exactly how you want the
conversion process handled
using a color-defined Engine,
and color conversion Intent.

You can adjust for black point
when converting color spaces,
dither color channel
information when converting
between color spaces and
compensate for Scene-referred
Profiles.
◆ Advanced Controls: Desaturate
Monitor Colors gives you the
ability to control the viewing of
a color space on different
monitors; however, if activated,
images will print differently
than viewed. You can also
decide what Gamma level is
used when blending RGB
values.
To save col or sett ings as a pre se t,
click Save, and then save the file

Synchronizing Color Settings Across CS5
When you set up color management using Adobe Bridge, color set-
tings are automatically synchronized across all Adobe Creative Suite
programs, which makes sure colors look consistent. It's a good idea
to synchronize color settings before you work on new or existing
documents, so the color settings match from the start. To work with
color settings, click the Edit menu, click Creative Suite Color
Settings, select a color setting from the list, and then click Apply. If
the default settings don't suit your needs, select the Show Expanded
List of Color Settings Files option to view additional settings. To
install custom color settings, click Show Saved Color Settings Files.

When you work on a color document, you're viewing the image using
your own computer, with a specific version of Photoshop, and a unique
monitor calibration. What you need is a way to preserve the visual set-
tings of the document. In other words, you want someone else to see
what you see. The ICC (International Color Consortium) color profiles
provide a universal way of saving (called tagging or embedding) a
mathematical definition of a particular color space, and gives you a
reasonable certainty that the document will display correctly on other
devices. Although there are several file modes that accept ICC profiles,
the two most common are RGB and CMYK.

To save the fil e
with the newly created custom
profile, the file must be saved as
an EPS, DCS, or PDF.
Click the Save As (Win) or Where
