Digital BW, The Print

For what it's worth, over the past three months I have now printed many 
hundreds of 13 x 19 prints on a 2400 in ABW Neutral.  The yellow ink 
usage is quite minimal in terms of ink actually used (as opposed to a 
microscopic examination of a print where yellow is visible).  Over 
about 100 cartdrige changes, the yellow has been changed at almost 
exactly the same rate as the cyan and magenta--which is to say that 
most of the yellow seems to go into cleaning cycles.  Because of these 
pesky little cartridges and the need to keep them in inventory, I have 
an exact record of usage for each of the eight.  The CMY cartridges are 
used at about one-quarter the rate of the others, with the LK being the 
most used of all inks.  After that, in descending order of use, it's 
LLK, MK, LC, LM.


To be specific on the driver settings, I am using:  
ABW, "neutral," "light," MK, and VFA or EEM.
