• Objects set in spot colors can be preserved, converted, or mapped (aliased) to any other ink present in the document.

Objects include Separation, DeviceN, and NChannel color spaces. 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.

Note: If you want to convert specific spot plates, use Ink Manager in combination with the Convert Colors tool. To convert

only specific spot plates to process, map them to process in Ink Manager. Otherwise, all spots in the document are converted

to process if you have selected Spot Color as the color type.

Convert document colors

1 In the Convert Colors dialog box, select a conversion command. If the list contains no existing commands, click Add

to add the default conversion command.

2 Select the conversion command that you want to edit, and then select an option from the Matching Criteria:

Object Type Specifies if you want to convert the colors for all objects or for a specific type of object within the

document.

Color Type Specifies the color space of the objects to be converted.

Text Size Specifies the minimum and maximum text size for text objects to be converted.

3 Select one of the available convert commands:

Preserve Keeps objects in the selected color space when the document is output.

Convert To Profile Uses the destination space profile to convert color objects to a common ICC profile for an output

device.

Decalibrate Removes embedded profiles from the matching objects.

4 Specify the conversion profile.

5 Select the rendering intent to use for conversion. The default is Use Document Intent. If you select any of the other

intents, the selected intent overrides the document intent for the conversion.

6 Select Embed to embed the profile. Selecting Embed tags all objects with the selected conversion profile. As an

example, a document can contain five objects: one in grayscale and two each in the RGB and CMYK color spaces.

In this case, you can embed a separate color profile to calibrate the color for each color space, for a total of three

profiles. This process is useful if your RIP performs color management of PDFs or if you are sharing PDFs with other

users.

7 Select Convert Colors To Output Intent and specify the output intent profile to be used instead of the document’s

current output intent. An output intent describes the color reproduction characteristics of a possible output device

or production environment in which the document is printed. This choice is not available if the document does not

have an output intent. (PDFs that don't comply with standards, such as PDF/X or PDf/A, often lack an output

intent.)

8 Specify the pages to convert.

9 Select any additional conversion options:

Preserve Black Preserves any black objects drawn in CMYK, RGB, or grayscale during conversion. This option

prevents text in RGB black from being converted to rich black when converted to CMYK.

Promote Gray To CMYK Black Converts device gray to CMYK.

Preserve CMYK Primaries When transforming colors to prepare CMYK documents for a different target print

profile, preserves primaries. For colors with just one colorant, Acrobat uses that colorant. For colors with more than

one colorant, Acrobat finds the color with the smallest color difference.
