My suspicion would be that QTR's output is more linear than the Epson driver, particularly if your setup was hardware linearized. Therefore, the fact that you prefer that particular file through the Epson driver only means it hasn't been optimized for QTR. Softproofing would help you, either a custom dot gain curve made by eye, or a real icc softproof profile of QTR output. That would help you get where you want faster, by adjusting your files apropriate to the more linear output. The fact that one arbitrarily matches your monitor better than the other is not conclusive. Is your monitor hardware calibrated? When you say it matches better, are you using some sort of softproof of the Epson output to compare? You see the complications here. The bottom line is that you should be able to tonaly come nearly indistinguishable between output systems one way or another. The dmax difference is another issue, but sometimes a conrastier print only appears to have higher dmax, and I believe the gimp drivers allow as much ink load and dot size as the Epson driver, Roy could speak to that.
