creating type for display on the web, consider that anti-aliasing
greatly increases the number of colors in the original image. This
limits your ability to reduce the number of colors in the image
and thus to reduce the size of the image file. Anti-aliasing may
also cause stray colors to appear along the edges of the type. When reducing
file size and limiting the number of colors are most important,
it may be preferable to avoid anti-aliasing, despite the jagged
edges. Also, consider using larger type than you would use for print.
Larger type is easier to view on the web and gives you more freedom
in deciding whether to apply anti-aliasing.
