Just to "ditto" much of what Martin mentioned....
I've no clue what Epson offers out-of-the-box for driving the SpectroProofer.....my experience is with GMG ColorProof.
With GMG, it's *primarily* used for auto-recalibration (unattended if you wish on a schedule that you can set).
It can also be used for creating GMG MX4 profiles if you wish but the target choices are somewhat limited, particularly for the "gamut" files that GMG uses for calibration and profile calculation. I think a lot of us GMG installers use the built-in spectro for calibration but largely make our MX4 and ICC profiles "off-line" using an iSis or some other spectro. Reason for this would be for speed, convenience and a wider choice of targets. The Spectroproofer, along with GMG ProofControl, can also be used for in-line proof verification. Once the proof is finished printing, the Spectroproofer can measure the media wedge/control bar, send the data to ProofControl which will then pass/fail the proof and optionally print the label right on the proof.
As for making ICC printer profiles, theoretically you could do this with GMG by capturing the measurement data from the SpectroProofer and then converting/exporting the data to CGATS format and then importing this to the profile application of your choice. Not done often with GMG since their MX4 profiles tend to do a superior job over ICC profiles but it's possible.
