John,
We haven't experienced any problem scanning 1-bit stuff with Microtek's
DA (or with VersaScan, their dedicated program that we've used for years
previous to the new DA) at all. It's _very_important_ to keep the glass on
your scanner clean, and dirty glass is about the only problem we've ever
had with crud in the white spaces (although there is occasionally a wee bit
of flack – it's easily ignored by Streamline, or "erased" before the file
is saved).
When preparing photos for Lino (or CG) output, we follow a pretty
simple procedure. First, we invoke Digital Darkroom, and scan out of that.
When the picture is scanned, we then adjust brightness and contrast to
provide optimal appearance.
We then "flash" the photo, duplicating with DD what printers do in the
darkroom. This drops off the top and bottom 10% of the blacks and whites,
providing a less harsh appearance and eliminating "holes." To do that,
choose "Modify Main Map (CMD M)" and change the values from 1 to 256 with
values from 25 to 225. This will soften or "flash" the picture. Choose
"Map to Image" to make the change permanent, and then save crop and save
the image with the appropriate name. Between this and XPress's new
built-in dot-gain correction for Lino's, we're getting great halftones!
