I have two questions about those numbers. IIRC 2.0 or thereabouts was a 
fairly typical dMax number for silver papers and in actual printing 90% of 
dMax or roughly 1.8 was about the "blackest black" that was actually desired 
(because of the loss of detail in slighly lighter shadow areas printing the 
darkest  shadows at dMax caused). At least in part because of this, the ANSI 
standard for measuring silver papers' density range doesn't begin at dMax, 
ANSI uses 90% of dMax as the starting point.

With Eboni matte black ink in the 2200 and printing on EEM, I measure dMax 
at 1.8 or about the "blackest black" I would print at if I were making a 
traditional silver print (at least I think it is, dMax numbers of silver 
papers are from memory, it's been several years since I actually tested 
papers in a darkroom).

So I guess I'm asking two questions: (1) where does the 2.4 number in the 
quoted statement come from? (2) assuming it's a number you or someone else 
has obtained in printing a test strip or making a print, is it considered 
desirable in digital printing to print important shadow areas at that high a 
dMax (i.e. is digital printing different from traditional silver printing in 
that respect?).

Yes but why would you want to do black only with a 4800?  The Advanced B&W
output to photo paper is excellent and sooooo simple.  Dmax to matte paper
hasn't changed that much but a RIP will let you boost ink limits.  Still the
look of 1.7dMax is a long way off 2.4dMax.  BO's biggest strength is its
simplicity in achieving metamerism-free prints.  This is not an issue with
the 4800.

The bottom line is that the 4800 produces fantastic photo paper output
whereas the 4000 doesn't.  Toning is easy.  Matte paper output (other than
the toning through the driver) is not materially advanced in my view.
