Digital BW, The Print

Dear Friends,

I could use advice. When I print using the Epson 2400 native black and 
white mode, I get a nice neutral colored print, but the darks are too 
dark (e.g., irises in eyes end up looking like extended pupils -- too 
dark). The QuadTone RIP does a noticeably nicer job separating 
intensity levels, but (at least when using a 50/50 blend of warm and 
cool -- on epson enhanced matte) it produces colors with a noticably 
greenish tint. I'd really like to get the best of both worlds: neutral 
color but the right curves. And thoughts or advice? I assume QTR uses 
color inks, and the Epson driver doesn't, leading to the difference I 
see in tonality. Is that right? What am I missing? Thanks!
