Digital BW, The Print

but if i'm actually printing with gray inks, or cool/warm grays, not 
color inks,  what good does having equal values of R.G.B do me? it 
doesn't mean my print will be neutral, only my photo in photoshop.

 does that make sense? after aplying an RGB curve to get the (gray) 
inks to "print" properly, the image is such a rainbow, the R=G=B -> 
neutral grey doesn't apply.

 or is there something i'm missing in you previous post?
 maybe i'm unsure of what you mean.
