Color management part 4
To customize color settings
For most color-managed workflows, it is best to use a preset color setting which has been tested by Adobe Systems. Changing specific options is recommended only if you are knowledgeable about color management and very confident about the changes you make.
After you customize options, you can save them as a preset. Saving color settings ensures that you can reuse them and share them with other users or applications.
• To save color settings as a preset, click Save in the Color Settings dialog box. To ensure that the application displays the setting name in the Color Settings dialog box, save the file in the default location. If you save the file to a different location, you must load the file before you can select the setting.
• To load a color settings preset that’s not saved in the standard location, click Load in the Color Settings dialog box, select the file you want to load, and click Open.
About color working spaces
A working space is an intermediate color space used to define and edit color in Adobe applications. Each color model has a working space profile associated with it. You can choose working space profiles in the Color Settings dialog box.
Aworking spaceprofile acts as thesourceprofile fornewlycreated documentsthatuse theassociatedcolor model. For example, if Adobe RGB (1998) is the current RGB working space profile, each new RGB document that you create will use colors within the Adobe RGB (1998) gamut. Working spaces also determine the appearance of colors in untagged documents.
If you open a document embedded with a color profile that doesn’t match the working space profile, the application uses a color management policy to determine how to handle the color data. In most cases, the default policy is to preserve theembeddedprofile.For more informationonsetting up colormanagementpolicies.
Working Space options
To display working space options, choose Edit > Color Settings. To view a description of any profile, select the profile and then position the pointer over the profile name. The
description appears at the bottom of the dialog box.
RGB Determines the RGB color space of the application. In general, it’s best to choose Adobe RGB or sRGB, rather than the profile for a specific device (such as a monitor profile).
sRGB is recommended when preparing images for the web, because it defines the color space of the standard monitor used to view images on theweb.sRGBisalsoagood choice when workingwithimagesfromconsumer-leveldigital cameras, because most of these camera use sRGB as their default color space.
Adobe RGB is recommended when preparing documents for print, because Adobe RGB’s gamut includes some printable colors (cyans and blues in particular) that can’t be displayed using sRGB. Adobe RGB is also a good choice when working with images from professional-level digital cameras, because most of these camera use Adobe RGB as their default color space.
CMYK Determines the CMYK color space of the application. All CMYK working spaces are device-dependent, meaning that they are based on actual ink and paper combinations. The CMYK working spaces Adobe supplies are based on standard commercial print conditions.
Gray (Photoshop) Determines Grayscale color space of the application.
Spot (Photoshop) Specifies the dot gain to use when displaying spot color channels and duotones.
Adobe applications ship with a standard set of working space profiles that have been recommended and tested by Adobe Systems for most color management workflows. By default, only these profiles appear in the working space menus. To display additional color profiles that you have installed on your system, select Advanced Mode (Illustrator and InDesign) or More Options (Photoshop). A color profile must be bi-directional, that is, contain specifications for translating both into and out of color spaces in order to appear the working space menus.
