In QuarkXPress 8.1 and later, transparency effects no longer need to be flattened. QuarkXPress 8.1 can output native PDF 1.4 transparency, which works well with Prinergy. You can configure this by creating a new PDF style in QuarkXPress, and then going to the Transparency panel and selecting the Export Transparency Natively option. Be sure to check the other tabs to ensure the correctness of those settings. For more information, consult your QuarkXPress help.
