Digital BW, The Print

wow I guess everybody is tired of this topic on this group.  I found 
out that 2 piezotone ink can be used in the epson 4000 at the same 
time.  So I am going to use 3 printers total. One for netural bw k7 
ink, cool/warm netual bw, and the third for sepia ink(sundance).  Does 
anybody know of anyother company that makes sepia ink for inkjet? 
Since back in wet darkroom days selenium tone was caused by a 
protective coating, I am going to use Bradford Brilliant White paper 
for that effect.  Starting off with quadtone RIP then studioprint.  If 
I am missing anything somebody please let me know.
