Convert object colors
If certain objects in the PDF don’t match the color space of the document, you can use the TouchUp Object tool
to correct them. Unlike the Convert Colors tool
, which changes the color space of all colors in a PDF, the
TouchUp Object tool can change the color space of selected objects. For example, if you place an RGB image in a
CMYK document, you can use this tool to change only the RGB image and not affect the colors in the rest of the
PDF. You can change the color space temporarily or embed the profile with the object.
Note: The TouchUp Object tool doesn’t let you change the output intent, because that affects the entire document.
1 Choose Tools > Advanced Editing > TouchUp Object tool, and select the objects you want to convert.
2 Right-click/Control-click the selection, and choose Properties.
3 Click the Color tab.
4 From the Convert To menu, choose the profile for specifying the color space of the object. The current color space
of a single object (or identical color spaces for multiple objects) appears at the top of the Color tab for reference.
Different color spaces for multiple objects aren’t shown.
5 From the Rendering Intent menu, choose the translation method appropriate for the object.
6 (Optional) To embed the profile with the object, select Embed Profile.
7 Click Convert Colors.
Ink Manager overview
The Ink Manager provides control over inks at output time. Changes you make using the Ink Manager affect the
output, not how the colors are defined in the document.
Ink Manager options are especially useful for print service providers. For example, if a process job includes a spot
color, a service provider can open the document and change the spot color to the equivalent CMYK process color. If
a document contains two similar spot colors when only one is required, or if the same spot color has two different
names, a service provider can map the two to a single alias.
In a trapping workflow, the Ink Manager lets you set the ink density for controlling when trapping takes place, and
it lets you set the correct number and sequence of inks.
Note: InDesign and Acrobat share the same Ink Manager technology. However, only InDesign has the Use Standard Lab
Values For Spots option.
