I'll send you my odd-looking Arches HP profile for the 7500.  I don't 
think I sent that one previously.  I printed 21-step curves for all 
the "colors" of Eboni-6 and then made the profile largely based on 
smoothness.  The ink distribution is distinctly different than the 
usual profile.  For uncoated paper, a modern printer really is needed 
for better quality, however.  

I'll be interested in what you come up with for un-coated paper.  In 
my ideal world, that is what I'd like to use.  On the other hand, in 
my fade testing the best coated papers (like Premier Art HP) did 
better than the Arches HP un-coated.

Aside from the fact that I use 220 printers for intitial development, 
I've never tried to precisely match that printer to the others.  
After an inkset works well on the 220, however, I have high 
confidence it'll work well on most of the Epson 3 pl and up hextones 
we usually print with.  For monotone inskets, the k2 and k3 printers 
are essentially the same when inksets with near standard densities 
are used.  

After an inkset works well in the 220, I go to a 2200 for more 
closely matching the k2 group that I think is the prime printer group 
for B&W dedicated inksets in large format.  Hopefully, what I make 
for my 2200 will be very useably for the 7600 etc.  For example, 
since I use the 2200 for actual production work with the Carbon-6 
inkset, in my normal course of printing I'll be pumping out profiles, 
etc. for that inkset and k2 printers.  The profiles (ICCs), in fact, 
appear to work even on the 2400 with C-6 as is.

I'm not sure this is really responsive to your earlier question, but 
for what it's worth ...

Good luck with the project.
