Understanding Anti-Aliasing

Anti-aliasing improves the display of type against the background. You can use five anti-aliasing methods: None, Sharp, Crisp, Strong, and Smooth. An example of each method is shown in Figure 14. The None setting applies no anti-aliasing, and can result in type that has jagged edges. The

Sharp setting displays type with the best possible resolution. The Crisp setting gives type more definition and makes type appear sharper. The Strong setting makes type appear heavier, much like the bold attribute. The Smooth setting gives type more rounded edges.

QUICKTIP

Generally, the type used in your image should be the messenger, not the message. As you work with type, keep in mind that using more than two fonts in one image might be distracting or make the overall appearance look unprofessional.

Different strokes for different folks

You're probably already aware that you can use different methods to achieve the same goals in Photoshop. For instance, if you want to see the type options bar, you can either double-click a type layer or single-click it, then click the Horizontal Type Tool. The method you use determines what you'll see in the History palette. Using the double-clicking method, a change in the anti-aliasing method will result in the following history state 'Edit Type Layer'. Using the single-clicking method to change to the anti-alias method to Crisp results in an 'Anti Alias Crisp' history state.
