Proofing color on screen (soft proofing)
QuarkXPress provides display simulation that is accurate enough for soft proofing a range of output. Using the information in the source setup, output setup, and any other custom settings (such as different profiles applied to pictures), the flexible simulation options show how the same layout will look when output to different media and for different printing methods.
To perform soft proofing, choose an option from the Proof Output submenu of the View menu. The menu lists all the output setups available in the layout, so if you have imported custom output setups from a color expert, they are listed here. When you choose an option, the entire layout displays in that color space — including the Colors palette (Window menu) and any color swatches shown throughout QuarkXPress.
The Proof Output submenu (View menu) provides display simulation options so you can see how colors will output. For example, if you plan to convert spot colors to process colors or output an entire RGB layout as grayscale, you can preview how your choice will look.
