Digital BW, The Print

I hate to beat this to death but once you select a printing
profile in the Print with Preview -- there is NO SUCH THING
as UNTAGGED RAW DATA.  If there is no embedded profile it will
use the Working Gray Space.  It has to have a source profile in
order to apply the print profile.  It's never one-sided.  There
no such thing as converting a raw file into a print profile.

So if you guys compare results when printing with ICC profiles
the source profiles make a difference and if you see Untagged
then the working space is critical.
