This is just a shot in the dark but sounds like there are subtile shifts
in the white areas of your image caused by your scanner. This is
assuming the work was scanned as continuous tone instead of line art. If
this is the case, a quick solution is to simply increase the tolerance
of the paint bucket in the options pallete. A better solution is to scan
as line art (straight b&w) at a minimum of 300dpi. It won't look as good
on the screen but your printer will love it.
