Digital BW, The Print

Roy,
I used PS with no dither to do the conversion to 8-bit.
With the 16-bit file it plotted as a smooth curve, more or less.  The 8-bit
file showed up as distinct groups of 4 readings, then a jump to the next
group.
The 8-bit file data also had areas of behavior beyond my time and ability to
understand, but it could have been related to the ink partitioning, or using
the i1 in scan mode.

Best regards,
John Moody

John,

Didn't the 8-bit version show the same steps?  It ought to do pretty well.
8-bit doesn't mean only 256 steps because of averaging multiple pixels.
But it is important that you convert to 8 bits with something like Photoshop
that does an "intelligent" mapping rather than simple truncation.
