CCD resolution? Not a clue, but the optical resolution of the Scan Dual II
is something like 2820.

What's the ccd resolution of the scanner? I was hoping that the grain
aliasing, if that's really it is, was somehow 'tuned' to the size of a
4000 dpi scanner implying that you could avoid the problem either by
resolving the grain (not possible with current ccd scanners) or by going
below the treshold with a 2750 or whatever scanner.
