Digital BW, The Print

Hello Paul


Like everything else I sink my teeth into, I must try and find out 
what makes things tick.

What are the percentages of gray ink,  in each respective cartridge 
of the MIS UT-R2 inksets that go in the R220. Both the Neutral set 
and the Warm set.  Is there a difference between gray ink density,  
and ink percentage?  

Would you be kind enough to explain what the chemistry is that makes 
one set Neutral and one set Warm.

You suggest that by replacing the yellow positioned cartridge in the 
Neutral set,  with that of a respective Warm cartridge,  it will warm 
the Neutral prints.   Are there other combinations that you would 
recommend juggling?


Very much appreciated


Mike
