Note: Adobe cannot ensure the compatibility of PDF content being moved into and out of QuarkXPress since it does not use Adobe PDF creation technology or the Adobe PDF library. file and one application to manage. If the artwork requires layout, Adobe InDesign allows you to simply place the native Illustrator file, retaining its editability and live transparency. QuarkXPress version 6 can place PDF content into QuarkXPress documents. Because QuarkXPress does not share transparency-flattening models with Adobe products, the PDF file must be flattened before it is placed. Since the exact resolution and capabilities of the 12 end printing device are not necessarily known during the design process, you should use the highest resolution possible in the PDF flattening settings. This will result in large, uneditable files. A better practice is to place these files into InDesign, which can properly place and output PDF files, even those with live transparency, spot colors and duotones.
