Convert Colors

Acrobat X Pro adds many new features to the revamped dialog, including access to the Ink

Manager. Click the blue arrow under Document Colors to reveal or hide the color spaces and

spot colors lists.

To convert a document’s colors to a different color space:

1. Choose the Convert Colors tool in the Print Production task list.

2. In the Convert Colors dialog box, select a color type option from

the list of document colors. You can specify dierent conversion

options for dierent color spaces and colorants. For example, you

could embed separate color proles to calibrate color for grayscale,

RGB, and CMYK objects. is strategy could be useful if your RIP

color-manages PDF les or if you are sharing PDF les with others.

3. Select an option from the Action menu:

•Preserve: Keeps objects in the selected color space when you output

the document.

•Convert: Uses the destination space prole to convert color objects to

the chosen output prole.

•Decalibrate: Removes embedded proles from the color objects in

that color space.

•Map to: Maps a selected spot color to a specied process plate or

another spot color in the document.

4. Choose a destination prole that accurately denes the target out-

put device.

5. Specify which pages to convert.

6. Specify whether to embed the destination prole. If you embed

the prole as a source color space, Acrobat tags all images with

the destination prole. If you embed it as an output intent, Acro-

bat uses the destination prole as the output intent, replacing any

existing output intent.

Depending on the color spaces you select, the Convert Colors

command will preserve, convert, or map color values from the source

color space to the specified destination space as follows:

•Objects with untagged RGB data (DeviceRGB) convert from the work-

ing space RGB prole to the CMYK gamut of the destination space.

Untagged CMYK (DeviceCMYK) and grayscale (DeviceGray) values are

converted in the same way.

•Objects in device-independent color spaces (CalGray, CalRGB, or CIE

L*a*b) can be preserved or converted. If they are converted, Acrobat

uses the device-independent object’s embedded prole information.

•Objects set in spot colors (including Separation, DeviceN, and NChan-

nel color spaces) can be preserved, converted, or mapped (aliased) to

any other ink present in the document. Spot colors can also be

mapped to a CMYK process color, if the process color model of the

destination space is CMYK. Spot colors mapped to other inks can be

previewed in the Output Preview dialog box.

between the two applications. In Acrobat, you have the choice of
