You can also check "All Spots to Process" to output all spot inks as process. This is a nondestructive option: the spot inks are not actually redefined as process colors, but print and export as process builds (all conversions and ink alias operations performed in the Ink Manager are nondestructive). Caution: if there are several different definitions of what should be one spot color, outputting the colors as CMYK may result in inconsistent color, even if you've mapped all the extra spot colors to one ink. If this is the situation, the best way to achieve color consistency is to edit all objects and placed artwork to use one spot color or one consistent CMYK recipe. This may require that you edit placed artwork in the original applications, such as Photoshop and Illustrator, to achieve consistent color. About InDesign Program Versions InDesign CS4 can open a file created in any previous version of the program, with certain considerations. For example, in some environments, customers may request that the printer return final versions of files, reflecting any corrections requested by the customer or performed by the printer to facilitate imaging. If you haven't updated all of your workstations to CS4, beware of attempting to work on customer files with an older version of InDesign. While it's possible to export a file from InDesign CS4 as an InDesign Interchange file, opening that file in InDesign CS3 may result in some content being modified-or lost. Some content, such as Conditional Text, doesn't exist in CS3; hidden conditional content will be deleted when an Interchange file from CS4 is opened in InDesign CS3. All of the conditional attributes will be lost if the file is opened in InDesign CS3, resaved, then reopened in InDesign CS4. Thus, file fidelity will be lost in attempting to "round-trip" such files. Consequently, it's best to keep InDesign files in their original version throughout the life of the job. Cross-platform issues While InDesign files and popular graphics formats originating on a PC can be opened on a Mac (and vice versa), fonts can still be an issue. Windows-format TrueType fonts can be used under Macintosh OS X, and OpenType fonts are fully cross-platform. PostScript Type 1 fonts, however, are platform-specific. Attempting to replace a font with what seems to be the cross-platform equivalent can easily result in a changed appearance, or worse, text reflow. Using a font-conversion utility to convert a PC font to a Mac font (or vice versa) may result in a font with changed font metrics, which may result in text reflow. Additionally, you may find that the End User License Agreement (EULA) for the font forbids such conversions. It is strongly recommended that you keep files on their original platform unless you've determined that OpenType fonts are used throughout the job. Managing missing fonts When you open an InDesign file that's missing fonts, the Missing Fonts alert lists those fonts needed by InDesign that are not available. Note, however, that this initial list does not reference any fonts needed by placed graphics. Clicking the Find Font button takes you to the Find Font dialog box, in which all fonts required by the document itself are listed, as well as fonts needed by placed art (indicated by an icon). Click the Find First button to navigate to the first use of the font in the document. (The Find Font dialog box is available at any time by choosing Type > Find Font.)
