Specifying anti-aliasing

Anti-aliasing lets you produce smooth-edged type by partially filling the edge pixels. As a result, the edges of the type blend into the background.

When creating type for online use, 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 reduce the optimized file size, and may cause stray colors to appear along the edges of the type. When file size and limiting the number of colors are most important, leaving type without anti-aliased edges may be preferable, despite the jagged edges.

To apply anti-aliasing to a type layer:

Select the type layer in the Layers palette and do one of the following:
