For those who have a 4800, or those who are simply interested in the tonality of
the
Advanced B&W mode, you can download a set of soft proofs for Ilford Smooth Pearl
Paper
and Epson Premium Semi Gloss here:

http://homepage.mac.com/stevekale/stevekale2/FileSharing37.html

The .psf Adobe Photoshop soft proofing files have been constructed using a 256
step
wedge printed using:

• 4800 driver v2.33
• 2880dpi
• High speed off
• Fine detail
• Advanced B&W mode
• The noted hue (cool, neutral, warm or sepia)
• Darker

The soft proofs have:

• Preserve RGB numbers checked (PS CS2 lingo)
• Simulate Black Ink checked

The step wedge was measured using Gretag Macbeth's Eye One spectrophotometer.

On a Mac the .psf files should be placed in:

~/Library/Application Support/Adobe/Color/Proofing

I have done soft proofs for Ilford Smooth Pearl (ISP) and Epson Premium
Semi-gloss (PSG)
so far. I do not intend to do proofs for other options (eg dark, lighter) but
may add other
papers over time, eg some matte papers. The Darker setting produces very good
results
from a Gray Gamma 2.2 workspace and I would rather tweak a soft proof with a
"print
curve" than tweak at the driver level except for picking hue.

Even though images are printed with No Color Adjustment/Same as Source and hence
only
the file numbers are sent to the printer (no profile), the appearance of the
image on your
display depends on its embedded ICC profile. (Assign a new profile and the
colors
associated with the same file numbers change. Convert to a new profile and the
underlying file numbers are changed so that the image looks the same with the
new
profile). My assumption is that Epson worked with Adobe RGB (and hence its
subset Gray
Gamma 2.2) when creating the settings for the Advanced B&W driver. This seems
to be
born out experience thus far. Therefore I intend to use Gray Gamma 2.2 as my
B&W
workspace.
