Use the QuarkXPress or Adobe InDesign software to change a multi-page job into multiple single-page files before bringing it into Prinergy.
This may require a third-party utility.
Follow the instructions for the software that you're using:

• For InDesign—http://indesignsecrets.com/page-exporter-utility-peu-5-script-updated-for-cs3.php. New files use the naming convention <filename>.P02.pdf.
• For QuarkXPress 7—From the Edit menu, select Output Styles. Select the PDF Output Style that you want to use. In the Pages pane, select Export pages as separate PDFs. New files use the naming convention filename (Page 02).pdf.
• For QuarkXPress or InDesign—http://exportools.badiasoftware.com

Next: Make corrections to the job by overwriting a single page.
