Phil, does the scanning software have a setting for "greyscale" or "8
bit greyscale" or "256 shades of greyscale" ? I find using the
greyscale setting makes a better picture of a schematic then "black &
white". B&W won't give you any grey areas in the lines for your eyes to
blend in and make the lines look smooth, whereas 256 shades of greyscale
will leave shades between white and black in the lines, and your eyes
will blend these shades together and make lines look smooth. A good
example is the circle around a transistor symbol on a schematic. With
B&W setting, the circle might look jagged, whereas it will look smoother
using greyscale.
Using greyscale over B&W will make the file size larger though.
