Hmm, wouldn't it rather be the printer with the smallest gamut?

However, inkjets CAN be made to match each other, for example,
within the
same company. It all depends what you want to achieve. If you
are doing
inkjet production printing it makes sense to be able to send
jobs to any
printer with the same result. In this case you'd profile the
printer with
the largest color gamut and use that as a source profile
through which you'd
convert files going to the other printers, each of which of
course would
have its own output/paper profile. Matching all printers to a
common RGB
working space like Adobe RGB makes little sense for reasons I
won't go into
here.

Good question. You may end up having to choose between doing the best
you can to match the "best" output or "dumbing down" all the color to
match the "worst" in the interest of consistency. The solution may
also depend on just how different the color capabilities of the
printers are. In a typical proofing scenario it's as you describe
because the only output that counts is in fact the one with the
smallest gamut, i.e., the press. In that case we hope that all the
proofing devices can reproduce the target gamut as well as match all
the tints and overprints in the reference set to a low dE. Here one
can safely point all the printers at the CMYK reference profile and
rely on the accuracy of the RIP and profiles (optimization, etc.) to
deliver visually indistinguishable results without resorting to
printer-printer matching.
