Comments To change the default settings for soft proofing to something other than the default (CMYK), close all images and select View > Proof Setup > Custom. Enter the desired Proof Condition, click the Save button, give your custom setting a descriptive name and click Save. Your newly created settings will automatically be at the top of the Custom Proof Condition drop-down menu. Click Ok to exit the Customize Proof Condition dialog and return to View > Proof Setup and select your settings. Now, when you open your file and choose View > Proof Colors (Command (Mac) / Control (Win) + Y), your custom setting will be the default device to simulate.
