Digital BW, The Print

Ok, I was recently challenged toquestions, so the following is a 
couple that I have. 


My used 3000 is now producing fine prints after I did a stack of 
head adjustments. The Peizo inks that i had in my 1160 CIS system I 
transferred to some empty 3000 cartridges and everything is 
wonderful apart from a slight cast from the magenta postion. My 
question to the forum is, "Why use Joe Cones inks when I can get MIS 
inks much cheaper?" I am sure that there must be a good reason. 
If I do use the MIS inks will they intermix with the Joe Cone inks?

I notice in all the workflows that the conversion from RGB color to 
grayscale is easy using the mixer channel or using the desaturated 
color method. But some of my prints look muddy, when I tried to 
correct with the sliders,indeed when I did the RGB to grayscale 
conversion in PS I end up often with gaps in the histogram on the 
dark end, which resulted in the shadow area of my prints looking 
like they had been posterised. Selection and applying noise helped a 
bit, but not a great deal. Any comments on this one?

I also notice that the Photo section of this forum is empty,how 
about putting some examples of our work there to see what others 
might aspire to? 
My current interest is in infrared. I am personally new to using the 
Piezo/MIS system, but I feel that I am getting there!
