FWIW, SWOP ink black (not rich black) is pretty light.
I have heard that before, but can't find anyone who agrees with it.
I guess you haven't talked to anyone who owns a densitometer,
colorimeter, or spectrophotometer.
0CMY100K is not a value you're going to get from any reasonable
RGB-to-CMYK conversion. If you spec 100K in an RGB document, you
don't get 100K, you get the RGB equivalent, which is substantially
lighter than RGB 000. Any time you specify a color in a mode other
than the document's native one, the app figures the Lab equivalent of
what you specified (which in the case of SWOP coated is Lab 12,2,0),
and translates it to the native mode of the document. In Adobe RGB,
SWOP coated 100K translates to RGB 39,36,37).
If you want to preserve 0CMY 100K across applications, you need to
start out in a CMYK document. (There is every reason in the world for
Photoshop to interpret an RGB color that you specifed as 0CMY100K as
a gray. If it did otherwise, you'd get no shadow detail in images...)
