This is the profile that will be used to convert any device CMYK
color in the Bitmap to a device independent color. This is the case
when the output color space is device independent, for example Lab.
This also happens when EmbedColorProfile is set to "standard" or to
the path of a color profile. This always indicates that the output
will be device independent.
You can set this property to the path of a color profile, or to
"device" or to "standard". See the discussion in
EmbedColorProfile for further details.
