Just for for clarification, the default CMYK profile Steve refers
to is
InDesign's document CMYK profile (see ID's Assign Profiles dialog)
and not
the application's Working Space set in Color Settings. These two
profiles
are usually the same but sometimes not.
----------------------------------------------------------------
InDesign will assume the document color space, but there's a bug.
In a quick test I placed an untagged Illustrator element, the same
Illustrator element with a profile (a G7 profile), and a box in
InDesign. All 3 elements were colored 50c, 40m, 40y, 0k. I assigned
the US SWOP v2 profile to the document. I printed the file, using the
same G7 profile for the printer profile. In the resulting PDF the
untagged Illustrator element and the InDesign element did not come
out the same. They should have.
The InDesign element was transformed using the Perceptual intent
(which is what I had specified in the preferences). The Illustrator
element used relative colorimetric.
My take is that Ignore Linked Profiles is the appropriate setting
when your intention is that the CMYK values are to be passed to the
output device. If Ignore Linked Profiles is disabled, you should
expect that CMYK images containing a profile which does not match
the document-assigned CMYK profile will be converted to the
document-assigned profile, and the black channel will be
recalculated (which could be bad for certain images).
Only if you instruct InDesign to convert at some point. "Ignore
Linked Profiles" is not the same as "Convert to Working Space"
