About masks and weighted optimization

Photoshop and ImageReady automatically generate masks when you create a type layer or a shape layer. You can also manually create masks and store them in alpha channels. When you use a mask to apply optimization settings, the white areas of the mask describe the highest level of image quality, while the black areas for the mask describe the lowest level of image quality. (The level of optimization in gray areas of the mask decreases by a linear scale.)

Weighted optimization is available for specific settings in the Optimize panel/palette, as indicated by the mask button J. To access the weighted optimization dialog box, simply click the mask button.
