Yes to a color-managed workflow, I have a Gretag Macbeth eye-one to profile my monitor.
I am using the default Epson profiles on epson premium luster.
Also on Ilford Smooth Pearl with the Ilford-supplied profile.
I have some of the new Harman FB Al, but have only done B&W with the ABW driver.
I've had the 3800 for about 8 months, I'm very comfortable with soft-proofing, printing from Photoshop CS2 and Lightroom. Michael's camera-to-print videos gave me some of the final tidbits I needed, especially with the soft-proofing.
The only thing I really knew to try was to get some custom profiles made.
