You need to create what Photoshop calls a soft-proofing custom condition. Go to View Proof Setup Custom. This brings up a small dialog window.
How To Install Icc Profiles In Photoshop Cs3
Select 'Custom' in the Custom Proof Condition drop-down list. Then pick your output profile from the Device to Simulate list, and choose your Rendering Intent and Black Point Compensation settings. (I normally use the Relative Colorimetric RI and select BPC; the Perceptual RI is often used as well.) Do not check Preserve RGB Numbers; make sure that box is cleared.Once that is all set, click the Save button and enter a good name for this combination of settings so you can find it again later. Once you have saved it, the new condition will now show up under that name in the list at the bottom of the View Proof Setup menu.
