Missing Profiles: Ask When Opening Displays a message whenever you open an untagged document. You will be given the option to override

the policy’s default behavior. Select this option if you want to ensure the appropriate color management of documents on a case-by-case basis.

Color conversion options

Color conversion options let you control how the application handles the colors in a document as it moves from one color space to another.

Changing these options is recommended only if you are knowledgeable about color management and very confident about the changes you make.

To display conversion options, choose Edit > Color Settings, and select Advanced Mode (Illustrator and InDesign) or More Options (Photoshop). In

Acrobat, select the Color Management category of the Preferences dialog box.

Engine Specifies the Color Management Module (CMM) used to map the gamut of one color space to the gamut of another. For most users, the

default Adobe (ACE) engine fulfills all conversion needs.

To view a description of an engine or intent option, select the option and then position the pointer over the option name. The description

appears at the bottom of the dialog box.

Intent (Photoshop, Illustrator, InDesign) Specifies the rendering intent used to translate one color space to another. Differences between

rendering intents are apparent only when you print a document or convert it to a different working space.

Use Black Point Compensation Ensures that the shadow detail in the image is preserved by simulating the full dynamic range of the output

device. Select this option if you plan to use black point compensation when printing (which is recommended in most situations).

Use Dither (Photoshop) Controls whether to dither colors when converting 8-bit-per-channel images between color spaces. When the Use Dither

option is selected, Photoshop mixes colors in the destination color space to simulate a missing color that existed in the source space. Although

dithering helps to reduce the blocky or banded appearance of an image, it may also result in larger file sizes when images are compressed for web

use.

Compensate For Scene-Rendered Profiles (Photoshop) Compares video contrast when converting from scene to output profiles. This option

reflects default color management in After Effects.

About rendering intents

A rendering intent determines how a color management system handles color conversion from one color space to another. Different rendering

intents use different rules to determine how the source colors are adjusted; for example, colors that fall inside the destination gamut may remain

unchanged, or they may be adjusted to preserve the original range of visual relationships when translated to a smaller destination gamut. The

result of choosing a rendering intent depends on the graphical content of documents and on the profiles used to specify color spaces. Some

profiles produce identical results for different rendering intents.

In general, it is best to use the default rendering intent for the selected color setting, which has been tested by Adobe Systems to meet industry

standards. For example, if you choose a color setting for North America or Europe, the default rendering intent is Relative Colorimetric. If you

choose a color setting for Japan, the default rendering intent is Perceptual.

You can select a rendering intent when you set color conversion options for the color management system, soft-proof colors, and print artwork:

Perceptual Aims to preserve the visual relationship between colors so it’s perceived as natural to the human eye, even though the color values

themselves may change. This intent is suitable for photographic images with lots of out-of-gamut colors. This is the standard rendering intent for

the Japanese printing industry.

Saturation Tries to produce vivid colors in an image at the expense of color accuracy. This rendering intent is suitable for business graphics like

graphs or charts, where bright saturated colors are more important than the exact relationship between colors.

Relative Colorimetric Compares the extreme highlight of the source color space to that of the destination color space and shifts all colors

accordingly. Out-of-gamut colors are shifted to the closest reproducible color in the destination color space. Relative Colorimetric preserves more

of the original colors in an image than Perceptual. This is the standard rendering intent for printing in North America and Europe.

Absolute Colorimetric Leaves colors that fall inside the destination gamut unchanged. Out-of-gamut colors are clipped. No scaling of colors to

destination white point is performed. This intent aims to maintain color accuracy at the expense of preserving relationships between colors and is

suitable for proofing to simulate the output of a particular device. This intent is particularly useful for previewing how paper color affects printed

colors.

Advanced controls in Photoshop

In Photoshop you display advanced controls for managing color by choosing Edit > Color Settings and selecting More Options.

Desaturate Monitor Colors By Determines whether to desaturate colors by the specified amount when displayed on the monitor. When selected,

this option can aid in visualizing the full range of color spaces with gamuts larger than that of the monitor. However, this causes a mismatch

between the monitor display and the output. When the option is deselected, distinct colors in the image may display as a single color.

Blend RGB Colors Using Gamma Controls how RGB colors blend together to produce composite data (for example, when you blend or paint

layers using Normal mode). When the option is selected, RGB colors are blended in the color space corresponding to the specified gamma. A

gamma of 1.00 is considered “colorimetrically correct” and should result in the fewest edge artifacts. When the option is deselected, RGB colors

are blended directly in the document’s color space.

Note: When you select Blend RGB Colors Using Gamma, layered documents will look different when displayed in other applications than they do

in Photoshop.
