Default Preflight Profiles Acrobat 9 Pro includes more than 50 prebuilt preflight profiles, which are designed to identify potential problems in specific workflows and, in some cases, fix problems. Included are profiles that check for font embedding, text using rich black, violations of total area coverage limits, and more. New fixups give you the ability to merge spot colors with different names, convert from and to spot colors, assign objects to layers, embed fonts, and much more. You can also customize a preflight profile to match your specific needs (see "Customizing a Preflight Profile" later in this chapter). Profiles are listed under categories: • Acrobat/PDF version compatibility: Checks for the version of Acrobat required to open the file. • Create PDF layers: Options include creating separate layers for vector, text, and image content, or placing objects on layers based on their transparency or overprint settings. • Digital printing and online publishing: Checks to see that a PDF file meets the requirements for common black-and-white or color digital printing conditions, or examines and optimizes a file for online use. • PDF analysis: Includes multiple profiles to check for common issues, such as fonts that are not embedded, white objects set to overprint, and low-resolution images, and more. • PDF fixups: Repairs common problems. Fixups can be used separately, or attached to a preflight profile, enabling you to automate some common edits, such as converting RGB content to CMYK. • PDF/A compliance: Checks for compliance with PDF/A-1a or PDF/A-1b specifications. Fixups to convert files to compliant files (when possible) are also listed in this category. (The PDF/A specifications are for archival storage of PDF files.) • PDF/E compliance: Includes checks for compliance with the Engineering standard, plus fixups to convert a file to PDF/E if possible, or remove PDF/E information if necessary. • PDF/X compliance: Checks for compliance with PDF/X-1a, PDF/X-3, PDF/X-4, PDF/X-4p, PDF/X-5g, or PDF/X-5pg specifications. Fixups to convert files (when possible) to compliant files are also available in this category. • Prepress: Includes profiles geared toward magazine ads, sheetfed offset, web offset, and newspaper conditions. Using Preflight Profiles To preflight an open PDF document with an existing profile: 1. Choose Advanced > Preflight, or click the Preflight button ( ) in the Print Production toolbar. 2. Choose the category that most matches your needs-Acrobat/PDF version Compatibility, Create PDF layers, Digital printing and online publishing, PDF Analysis, PDF fixups, PDF/A compliance PDF/E compliance, PDF/X compliance, or Prepress-and click the triangle to the left of the category to reveal the profiles within the category. If you have imported profiles, you will have an Imported profiles category as well. And if you have created custom profiles, you will also have a Custom profiles category. 3. Select a preflight profile that matches your output criteria. The profile description appears under the profile name. You can also click the Further Options triangle at the bottom of the panel, to specify whether to run the preflight check just for visible layers, or to limit the preflight to just a range of pages. 4. Click Analyze or Analyze and Fix. Adobe Creative Suite 4 Printing Guide 104
