I'll hazard two guesses --

    1. The Epson drivers "know" the native gamma of the platform they are
running on (Windows @ 2.2, Mac @ 1.8), and are compensating for that as they
send the data to the printer.

    2. The users of these curves (and I have no direct experience myself)
have not calibrated their monitors, and so the curves are compensating for
*both* the characteristics of the ink *and* the characteristics of the
monitor.  However, I can't see how this would produce decent results, since
uncalibrated monitors will be different even on the same platform.
