Preflight Audit Trail You may wish to embed an Audit Trail in a preflighted PDF to help keep track of the preflight results and the profile used. The Audit Trail feature will also reflect whether the PDF has been altered since the audit trail was embedded. PDF Fixups When Fixups are included in a Preflight profile, Acrobat will automatically repair some of the problems that the preflight process finds. Keep in mind that not all problems can be fixed in Acrobat. For example, image content of insufficient resolution can be pinpointed with Preflight, but there's no way to rectify such an issue within Acrobat. As with many problems in a PDF file, the origin of the issue lies much further upstream in the lifecycle of the job. It would be necessary to locate a high-resolution image, replace the low-resolution content in the original application, and generate a new PDF. A profile may contain a preflight check, a fixup, or both. To identify what components a profile contains, examine the icons to the left of the entry in the Preflight profile dialog box: • Preflight profiles which contain only checks will display a highlighted magnifying glass ( ) to the left of the name. • Fixups display a highlighted wrench ( ) to the left of the name. • Profiles that combine checks along with fixups will show both the magnifying glass and wrench highlighted ( ). Single Checks and Fixups Acrobat 9 Pro adds Single Checks and Single Fixups to streamline the finding and fixing of common problems, such as image resolution. Single Checks and Single Fixups can be run independently without needing to be incorporated into a Profile. Acrobat 9 Pro includes an extensive list of Single Checks, including checks for ink coverage, transparency, font embedding, text using rich black, black objects set to knock out, objects using Registration color, images below a threshold resolution, and many more. Single Fixups include convert Registration color to black, merge spot colors with different names, embed fonts, assign object types to layers for troubleshooting, and much more. You can also create your own Single Checks and Single Fixups. To create a single check: 1. In the Profiles panel of the Preflight dialog box, click the Select Single Checks button. 2. Choose Options > Create New Preflight Check. 3. On the right side of the dialog box, select a group, select a property for the group, and then click Add. The new single check appears in the group appropriate to its group and property. To create a single fixup: 1. In the Profiles panel of the Preflight dialog box, click the Select Single Fixups button. 2. Choose Options > Create New Preflight Fixup. 3. Name the fixup and specify the criteria. The new fixup appears in the group appropriate to its category and type. Layer Fixups Acrobat 9 Pro includes a new group of Fixups devoted to creating and manipulating Layers. Select the Single Fixup button for Fixups that create different layers for text, graphics, and images; create layer names for unnamed layers; put overprinting objects on a single layer, or put transparent object on a single layer. Think of these layers as "view groups" rather than layers as they exist in an Illustrator or Photoshop file: they enable you to selectively view components of a PDF, regardless of actually visual stacking order. For more information on creating, viewing, and printing PDF layers, see Acrobat 9 Pro Help, available under the Help menu. Adobe Creative Suite 4 Printing Guide 106
