Digital BW, The Print

Looks like this has been or will shortly be released for the 2200/7600 
printers.  There is a link on the following web site to a pdf 
description of the system (software, inks, papers).  They don't say 
specifically what the 7 inks are, but it appears as though they might 
be the quad blacks (neutral or warm?) plus C, M , and Y inks for 
toning.  Perhaps Antonis can elaborate on the composition of this 
inkset.
