Bingo! A QTR Create ICC/ABW flow that works . . .

After Steve's last suggestion (thank you Steve!) that I check the monitor black on an i1 calibration, I started to think about that. What I stumbled on has, for the first time, produced a nearly perfect screen to print match--astonishingly useful and very simple. The answer was: After monitor calibration, the contrast control on this Sony 19" LCD has to be turned down to 50% of whatever value was required for black point calibration with the i1. I have no idea why this works, but when you get down to that 50% figure, the print literally snaps onto the screen in an incredibly convincing way. The only thing that is not (of course) previewed is the hue of the paper white. On the chance that this workflow would be useful to someone else (unlikely, I guess, given all the discussions on the forum), here it is. 1. I1 monitor calibration to 65K and gamma 2.2. After calibration, the monitor contrast is reduced to 50% of the level required during the calibration. This 50% figure is a bit flexible, but not much on this monitor maybe + or - 2 %. A calibration to 50K will also work but results in a very warm screen image after contrast reduction. 2. Letting Photoshop manage color through an ICC profile created with the i1 and the QTR Create ICC Profile (which includes BPC in my version). (Thank you Roy and I will be sending money immediately.) Rendering is Perceptual and BPC is checked, though I don't think the latter matters with the version of QTR CICCP I am using. 3. A gamma 2.2 workspace. 4. A Soft Proof view that uses the ICC profile, perceptual rendering and BPC and Simulate Paper color checked (though I don't think the BPC matters). This Soft Proof provides a slight, but useful, improvement over the workspace view, pareticularly in the mid to high tones. 5. Epson ABW driver settings of "Neutral," which is to say no tweaks to the driver at all. I am printing on VFA and EEM for proofing and the two are virtually identical (except that the VFA has deeper and smoother blacks). I have also done profiles for the "Neutral" + light (driver neutral is "darker") but the prints are identical done through their respective profiles, so I'm just sticking with the standard Epson settings. Hey guys and gals, I'm thrilled! After four months working with this printer, it all finally fell into place. I hope someone else finds this useful. Walt
