Why do anti-aliased images created in PhotoShop have a white fringe?
PhotoShop delivers a perfect visual image, and a perfect anti-aliased image. Unfortunately, what you need is a perfect antialiased image and an edge-biased visual image. Do the biasing yourself by painting your PhotoShop document on a background almost the same color as your image. For instance, if you’re painting black text, paint it on a 99.5%-black background.
