That would be great.  I'd love to see some more comparisons.

The test file is at:
http://harrington.com/technical.psd.zip

All prints were done with no manipulation of the file.  All full page.
They were are scanned using an Epson 3200 at the 1200 dpi setting.
using the ordinary Twain plugin of Photoshop.  I let the software
pick the endpoints with Auto -- I think you need the full page to get
good endpoints so the preview can see the full range of densities.
