Anti-aliased text is text that uses color variations to make its jagged angles and curves look smoother. Director activates anti-aliasing by default. You can change this setting on the Text tab of the Property inspector (for more information, see Setting text or field cast member properties). Anti-aliasing functions the same way for embedded fonts and for system fonts that have not been embedded (see Embedding fonts in movies).
Using anti-aliased text dramatically improves the quality of large text on the Stage, but it can blur or distort smaller text. Experiment with the size settings to get the best results for the font you are using.
Director can anti-alias all outline (TrueType, PostScript, and embedded) fonts but not bitmap fonts. When you select a font that can't be anti-aliased, the message "This font can't be anti-aliased" appears in the Font dialog box below the font list. (Display the Font dialog box by selecting text or a text sprite and then selecting Modify > Font.)
