Converting colors
If your Adobe PDF document will be output to a high-end output device or incorporated
in a prepress workflow, you can convert color objects in the document to CMYK or
another color space. Acrobat uses the source color spaces of objects in an Adobe PDF
document to determine what (if any) color conversion is required, for example, from RGB
to CMYK. If a PDF file contains objects with embedded color profiles, Acrobat manages
the colors using the embedded profiles rather than the default color spaces. You can
convert the colors of a single page or an entire document.
