Sorry Jim, this suggestion is incorrect. The issue with scanning 300 DPI
line art is that typically (and I know this to be the case with Umax
scanners using Umax software) the image is scanned as a binary black and
white image.
Now when you "reduce" it to 72 - 100 DPI (which is screen resolution) if
you retain the black and white mode then you will get crap. This is because
you lose a lot of information. However, if you change the image to be an 8
bit grey scale image at the same time you resample it, then it will look
reasonable because the program can use antialiasing techniques to preserve
the information in the image.
