Anti-aliasing bad for fonts at small size.

I made a font but when viewed at a size less than 20, the anti-aliasing ruins the look of it. The text you are reading right now looks like it is bit-mapped. How do I make it so that my font doesn’t use anti-aliasing for small displays too?

Its to do with lack of hinting.

Please read the Frequently Asked Questions sticky thread at the top of this forum. Perhaps you can improve things by adding greyscale values.
