• Color Images: Bicubic downsampling to 300ppi; Compression = Automatic (JPEG); Image Quality = Maximum. • Grayscale Images: Bicubic downsampling to 300ppi; Compression = Automatic (JPEG); Image Quality = Maximum. • Output: Convert to destination color space; no embedded profiles. PDF/X-3:2002 The specification for PDF/X-3 builds on PDF/X-1a, adding support for embedded color profiles and thus allowing RGB and Lab content in addition to the color spaces supported by PDF/X-1a. Use this format in a color-managed workflow Setting include: • Compatibility: Acrobat 4.0 (PDF 1.3). Transparency will be flattened. • Color Images: Bicubic downsampling to 300ppi; Compression = Automatic (JPEG); Image Quality = Maximum. • Grayscale Images: Bicubic downsampling to 300ppi; Compression = Automatic (JPEG); Image Quality = Maximum. • Output: No color conversion; embedded profiles. PDF/X-4:2008 PDF/X-4 extends the PDF/X-3 specification, adding support for live, unflattened transparency, as well as layers. The inclusion of layers and live transparency may make PDF/X-4 files inappropriate in workflows using older devices and processes. Consult the documentation for your RIP and any other steps in your workflow, such as imposition, to determine if PDF/X-4 files can be processed correctly. Part of the PDF/X-4 standard is the requirement that a "conforming reader" application shall be used to properly process it, which may mean that you need to obtain a patch or upgrade for your RIP or other processes (such as trapping and imposition) that will handle PDFs (RIPs using the Adobe PDF Print Engine can correctly process PDF/X-4 files). Settings include: • Compatibility: Acrobat 5.0 (PDF 1.4). Live transparency is maintained. (Note that, while the official PDF/X-4 specification allows Acrobat 7.0 [PDF 1.6] compatibility, CS4 applications use Acrobat 5.0 compatibility.) • Color Images: Bicubic downsampling to 300ppi; Compression = Automatic (JPEG); Image Quality = Maximum. • Grayscale Images: Bicubic downsampling to 300ppi; Compression = Automatic (JPEG); Image Quality = Maximum. • Output: No color conversion; embedded profiles. Managing custom PDF presets Supplied PDF presets are stored in one common location for access by Illustrator, InDesign, Photoshop and Distiller (with the exceptions of application-specific presets noted previously). Because the presets are stored in a common repository, if you attempt to delete a preset, you'll receive an alert that deletion will affect more than the application you're using at the moment. User-created custom presets are also available to Illustrator, InDesign, Photoshop and Distiller, but are stored in a separate location from the factory presets. On the Mac, you'll find custom settings in [user]/Library/Application Support/Adobe/Adobe PDF/Settings. On a PC, they're stored in C:\Documents and Settings\[user]\Application Data\Adobe\Shared Documents\Adobe PDF\ Settings. As you establish methods for the creation of PDFs for your particular workflow, standardize all of your prepress workstations, and share those methods and the correct presets with your customers to ensure submission of appropriate PDF files as final job files. You can provide the correct PDF presets to your customers as *.joboptions files; they simply double-click the file and it's automatically installed in the correct location. The methods for exporting and importing saved PDF presets varies slightly by Creative Suite 4 component; see this document's section on the individual component (or consult the Help menu for the application) for specifics.
