encounter it twice: once for the InDesign RGB working space and once for the InDesign CMYK working space. The Profile or Policy Mismatch dialog box appears when a document opens on a computer that uses different color settings than those used to create the document. There are two possible types of mismatches: profile mismatches and policy mismatches. A profile mismatch simply means that the RGB or CMYK working space of the user who saved the document is different than the working space of the user who is opening the document. A policy mismatch is a difference in how each user resolves a profile mismatch. For example, one user might preserve color numbers (by ignoring embedded profiles), while another user might preserve color appearance (by applying embedded profiles). Preserving color numbers is typically correct for CMYK, but preserving profiles is typically correct for RGB graphics with embedded profiles. When you see a mismatch alert message, you can take one of these actions: • Reconcile the root cause of the alert message: Click Cancel and determine why the customer is using color settings that don't match yours. Then you can open the document and make one of the choices in the alert message. If practical, have the customer and your shop use the same color settings so that mismatches don't happen in the future. • Assume the document's colors were correct in the customer's environment: For an RGB mismatch, if the document's policy was Preserve and the customer's placed RGB graphics include embedded profiles, you can select Leave the Document As Is. There is usually no need to change the RGB (working space) Profile. For a CMYK mismatch, you may need to change the CMYK (working space) profile to your shop's standard. If the document's policy was Preserve Numbers and the customer's placed CMYK images do not include embedded profiles, you can select Leave the Document As Is. If the document's CMYK policy was Preserve, you may want to consult with the customer to confirm that they intended to use the Preserve policy, because it is not CMYK-safe. If the document contains CMYK objects with embedded profiles, the Preserve policy keeps them, which may result in CMYK color conversions at output time. If that was not what the customer intended, simply choose Ignore Embedded Profiles to open the document in a safe CMYK mode. • Defer the decision until later: Select Leave The Document As Is, but at a later time be sure to choose Edit > Assign Profiles to verify that the profile assignments for both RGB and CMYK are appropriate, and then, if necessary, change the profiles. Caution: If there was a policy mismatch, be aware that saving the document on your computer applies your current color settings policy to the document. You can change the profile assignment of an individual image. For example, if you know that a placed image was saved with the wrong profile, you can either assign the correct profile or simply ignore it if the correct profile would match the document's working space. Note: You can change the profile assignment of bitmap images only, such as Photoshop or TIFF files. You can't change the profile assignments of EPS or PDF files. To change the profile assignment of an individual image: 1. With the Direct Selection tool (white arrow), select an image. 2. Choose Object > Image Color Settings. 3. Assign the correct profile, and click OK. Assigning a profile to one graphic doesn't affect any other graphics and doesn't change the working space of the InDesign CS4 document. At any time you can use the Info panel to identify the color profile of a selected image. See the "Common Resources" chapter for more information about color management in Creative Suite 4.
