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 the whole document or for a specific type of object within the document. Color Type Specifies the color space for conversion. Text Size Specifies the minimum and maximum text size for text objects. 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 color objects in that color space (or alternate space, if one is specified for a spot color). 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 convert every object to the output intent. An output intent describes the color reproduction characteristics of a possible output device or production environment in which the document is printed. 8 Specify the pages to convert. 9 Select a conversion option if applicable: Preserve Black Preserves the color values of 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. 10 Click Document Colors to see a list of color spaces and spot colors in your document.
