Digital BW, The Print

I have been using the Lysonic E (color ink) in an Epson 3000.  
Printing quite a lot (test prints mostly) and working towards a 
neutral (though it's not a concern for me at all).

The observation...

The black in is quite cool to blue therefore when working towards a 
neutral the printer is using a lot of magenta to balance.

Rational for the observation...I had acheived the 'neutral' I wanted 
and for fun printed one with black ink only to compare.  Been 
watching the ink monitor level on magenta drop at a faster rate than 
black.

Simple observation I know but one to consider when you get low on 
inks and need to order more ;-)
