Converting colors to a destination color space
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 working space RGB
profile to the CMYK gamut of the destination space. The same is done with untagged
CMYK (DeviceCMYK) and grayscale (DeviceGray) values.
Objects in device-independent color spaces (CalGray, CalRGB, or CIE L*a*b) can be
preserved or converted. If converted, Acrobat uses the device-independent object's
embedded profile information.
Objects set in spot colors (including Separation, DeviceN, and NChannel 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. (See
To open the Convert Colors dialog box:
Choose Tools > Print Production > Convert Colors, or select the Convert Colors tool
on the Print Production toolbar.
To convert a document's colors to a different color space:
1. In the Convert Colors dialog box, select an option from the list of color spaces and
colorants used in the document.
Color spaces with currently selected actions
2. Select an option from the Action menu:
Preserve keeps objects in the selected color space when outputting the document.
Convert uses the destination space profile to convert color objects to a common ICC
profile for an output device.
Decalibrate removes embedded profiles from the color objects in that color space.
Note: Spot colors can be mapped to the destination space by way of another ink, called an
alias.
3. Specify the space to which colors will be converted. The destination profile defines the
target output device for the converted color spaces.
4. Specify the pages to convert.
5. Select a conversion option:
Embed Profile As Source Color Space tags all images with the destination profile selected
in the Profile menu.
Embed Profile As OutputIntent uses the destination profile as the output intent.
Don't Embed Profile does not tag objects with the profile.
Preserve Black Objects preserves the color values of objects drawn in CMYK, RGB, or
Gray during conversion. This prevents text in RGB black from being converted to rich
black when converted to CMYK.
