Right now we only document the first step, but we'll add notes for the others later. If you have not created a custom preset path you should probably do so. If you have not saved an emphasis curve then you should do so. You want to adjust the curve so that anything that is somewhat dark is made really dark, and anything else is made white. Anything above the middle intensity is made completely dark, and anything below the middle intensity is made completely light.
Suggestions Use unlined paper.
When the paper has lines they can show up just as strongly as the writing. The digitizing process can make the images a bit rough around the edges and hard to read. Making your handwriting easier to read can compensate for this. The scanned images should not be wider than 700 pixels. If they are any wider, Netscape will use 2 pieces of paper to print it, which generally wastes paper and the students' printing allocation.
