I wish to contribute my experience with regards to matching colors between
printers. At one time, I had a client with two Epson 10600 printers, both
driven by the same EFI Colorproof 2.6 RIP and both printing on the same garbage
Imation paper. Of course, my client expected both printers to be exact matches
of each other. In my experience, this was rarely the case. Even if I started
with the same Ink Limiting values on both printers, they would never -- if ever
-- matched each other. The best I was able to come with, at one point, was to
profile one of the two printer and use that as a Source instead of using
SWOP2006_C3. That technique worked once or twice (my client was quite
impressed!) but then, it gave me results no better than had I attempted to
profile each printer separately? It could have been the printers were
'unstable' but what was I or my client to do? I had limited time to work on
these machines. It could have been the DTP70? Or, later, the iSis? I'll never
know. I later used the exact same technique for another client who was running
three Epson 7600 printers, same papers, Onyx RIP. I used the first profiled
printer as the Source of the other two and that worked well "once". The other
times I tried to use the same technique, the results were not very good. Break
down of the theory? I'll never know. But it was pure hell.

I have prints from Printer A that I am trying to match on printer B-- I also
have a profiling chart I have printed THROUGH printer A's profile, on printer
A (via assigning in PS) -- a "round trip" describing the output of the
profile.
The one thing I DON'T have is the same color measuring device that made
printer A's profile originally-- This could easily be the main differential,
but this is also why I obtained the round trip profiling chart.
