Rasterizing and anti-aliasing type

When you save artwork in a bitmap format--such as JPEG, GIF, or PNG--Illustrator rasterizes all objects at 72 pixels per inch and applies anti-aliasing to them. However, if your artwork contains type, the default rasterization and anti-aliasing settings may not produce the desired results. Illustrator provides several options specifically for rasterizing type. In order to take advantage of these options, you must rasterize type objects before you save the artwork.

To set rasterization and anti-aliasing options for type objects:

1. Choose a Rasterize command as described in Changing vector graphics into bitmap images.
2. Choose a method for rasterizing type from the Type Quality pop-up menu.
• Streamline to create slender, attenuated type.
• Outline to create slightly heavier type.
3. Choose an anti-aliasing option:
• None to apply no anti-aliasing and maintain the hard edges of type when it is rasterized.
• Type Optimized to apply anti-aliasing that is best suited to type. Anti-aliasing reduces the appearance of jagged edges in the rasterized image and gives type a smoother on-screen appearance. However, it can also make small text difficult to read.
