John,

No it has not been confirmed by Jon to my knowledge.

I my statement regarding the green content of the ink is based on 
viewing the results of Paul Roark's test comparing the magenta 
position inks of MIS VM and Piezo. From the group homepage go 
to "Files" then to "Message Related Files". You will find three jpeg 
files "Piezo-MIS dots" showing the two inks side by side on a piece 
of kleenex. As you can see the ink appears to be rather green. The 
green in these images is very close in shade to the green cast I 
personally see in Piezo prints under tungsten light. The Piezo prints 
look excellent in daylight to my eye by the way.

My thought that the green was added to balance an unwanted color 
shift in the opposite direction is speculation only.
