Print From Your Computer : Macintosh Printing (Mac OS X 10.5)

Manage Color
You can manage how colors are handled in your photos by selecting Color Management options from the Print window.
Select Color Management from the pop-up menu.
Color Controls lets you select a color Mode for printing the colors in photos and graphics: EPSON Vivid or AdobeRGB.
Gamma adjusts the midtone density in the print.
Advanced Settings adjust Brightness, Contrast, Saturation, and individual Cyan, Magenta, and Yellow color tones.
Fix Photo automatically analyzes your photos and, if necessary, adjusts the brightness, contrast, and saturation.
Fix Photo uses a sophisticated face recognition technology to optimize photos that include faces. For this to work, both eyes and the nose must be visible in the subject’s face. If your photo includes a face with an intentional color cast, such as a statue, you may want to turn off Fix Photo to retain the special color effects.
Off (No Color Adjustment) turns off printer software color adjustments so you can use the color adjustments in your program only.
When you’re finished, you’re ready to print.
