Digital BW, The Print

Hi all,

A totally noob question here. I am trying to find an inkset that 
actually has 6 shades that are used together (e.g. not a variable mix 
set). The ones that I have looked at so far seem to either have only 
four tanks or double up on two of the shades. I have an Epson 1280, 
Bowhaus IJC, an X-rite 810, and some really nice Hahnemühle papers 
(Photorag, really heavy Photorag and Japan).

Any points in the right direction would be greatly appreciated.

Thank you
Dimitri Katsaros
