Choosing advanced color management settings
When you choose color profiles, colors are matched between devices as closely as possible by the color management module (CMM) of the Kodak Color Management System, which is the default CMM. Color management modules are also known as “color matching modules.”
You can also use one of the following color matching modules:
•
|
|
Adobe CMM if it is installed on your computer. To download and install the Adobe CMM, visit the Adobe Web site.
|
Note that the Microsoft ICM, Windows Color System, and Adobe CMM do not change the color profiles that are used by CorelDRAW. If you want the application to use the same color profiles as those of the selected color management module, you must select the appropriate color profiles in the Color Management dialog box.
Out-of-gamut colors and rendering intents
Color gamut is the range of colors that devices such as monitors or printers can reproduce. Colors that cannot be reproduced by the output device are called out-of-gamut colors. Such colors need to be replaced by colors from the color gamut of the output device. To determine how out-of-gamut colors are replaced, you can choose one of the following rendering intents:
•
|
|
Absolute colorimetric — rendering intent that lets you simulate the output of one device, such as a CMYK printer, on another device, such as a monitor or inkjet printer. This rendering intent preserves the white point through conversions. For example, to render the bluish white of a source to an output on yellowish-white paper, cyan ink is added to the white areas of the output.
|
•
|
|
Automatic — default setting, which uses the Saturation rendering intent for vector graphics and the Perceptual rendering intent for bitmaps.
|
•
|
|
Saturation — rendering intent for vector graphics (lines, text, and solid colored objects), business graphics, and elevation maps. Vivid colors are reproduced by converting saturated colors in the source to saturated colors in the output, but often at the expense of color accuracy.

By enabling the gamut alarm, you can preview which on-screen colors cannot be printed accurately. The colors that cannot be reproduced are highlighted.
The gamut alarm highlights colors that a printer cannot reproduce accurately.
Embedding color profiles
When you import or export graphics, you can embed or attach color profiles. By embedding a color profile, you can ensure color integrity; anyone viewing or printing your work will use the same colors that you used.
Settings for separations and composite printers
There are advanced settings for separations and composite printers. You can link a color profile to a specific printer.
Color management styles
When you use color management styles, you can turn off color management or optimize the color display for different outputs.
To choose a color engine and rendering intent |
3.
|
|
In the Advanced settings dialog box, choose a rendering intent from the Rendering intent list box.
|
To enable the gamut alarm |
If you want to show CMYK in percentages, enable the Show CMYK in percentages check box.
|
•
|
|
You can map spot colors into the CMYK gamut by enabling the Map spot colors into CMYK gamut check box.
|
•
|
|
You can change the warning color of the gamut alarm by opening the Warning color picker and choosing a color.
|
To embed color profiles |
•
|
|
When you enable the Always convert using import options, as well as the Always embed using export option, you can choose a profile from the list box.
|
•
|
|
When you enable the Embed internal RGB profile or the Always embed using export options, certain file formats are exported with an embedded ICC profile. These file formats are TIFF, encapsulated PostScript (EPS), Corel PHOTO-PAINT (CPT), CorelDRAW (CDR), JPEG, Portable Document Format (PDF), and Adobe Photoshop (PSD).

To choose advanced printer settings |
•
|
|
If you choose an advanced setting, that setting overrides the profile that appears under the printer icon in the Color management dialog box.
|
To use color management styles |
•
|
|
Some color management settings, such as Default, Optimized for desktop printing, and Optimized for professional output, can cause on-screen colors to appear dull. This dullness is due to an on-screen printer simulation of the output. For more information, see “Displaying colors for different types of output.”
