Depending on which Fiery RIP, it may use ICC profiles directly and can do
a reasonably good job of simulating whatever you want (within limits of
the DocuColor). It supports an uploading of ICC profiles for the printer
and for conditions you want to simulate (press, or standard proofs). It's
nice to be in a position to feel comfortable editing a PPD file so you
can take the "Custom 1, Custom 2, Custom 3, etc." pop-up options and
rename them to the kind of simulation you've created. Otherwise you have
to create cheat sheet on paper (oooh bad) for everyone that tells them
"Custom 1" means simulate Commercial Matchprint, for example.
The older Fiery RIPs would use separate software that would create a
PostScript CSA from an ICC profile. An outstanding question is how to get
a profile for the actual proofer itself uploaded (not just the profile
for the output you want to simulate). I haven't heard an answer to this
yet.
For the Tektronix 780 you can only use PhaserMatch that comes with which
is essentially an OEM'd version of Monoco EZ Color. There is no point
using anything else unless you plan on training everyone how to cross
render, or get a copy of Compass Pro XT, or a separate color processing
software. If you want to use the device's built-in capabilities, you have
to use PhaserMatch.
The reason why is because PhaserMatch is essentially broken. PhaserMatch
does three things. Let's you build profiles, select a source &
destination ICC profile which are converted into a CSA and CRD then
inserted into the printer's PPD file, limited profile editing. The second
feature is broken in PhaserMatch. It will let you select any ICC profile
as a source (press profile for example), but will only let you select a
destination ICC profile (for the Tektronix printer) made with PhaserMatch.
This means that you wan't make custom profiles for the Phaser 780 with
any program other than PhaserMatch if you want to use the Phaser 780's
built-in color management capability (PostScript color management). At
least, not unless you know how to create your own CRD for the Phaser 780
and insert it properly into the PPD file.

Be aware that both of the toner based printers are CMYK printers. Also be
aware that Aurelon software comes with prebuilt proprietary profiles for
the inkjet printer. You will not need to create profiles for the inkjet.
I recommend using Mitsubishi paper with either printer, not Epson paper.
Aurelon has a prebuilt profile for the Mitsubishi paper.

Expect the behavior of the toner devices to fluctuate hourly, daily and
weekly. It's up to the color and toner gods as to how big of a deal this
fluctuation will be (and the customer's tolerances of course).
