USING ACROBAT X PRO 87 Creating PDFs Advanced panel options The Advanced options specify which Document Structuring Conventions (DSC) comments to keep in a PDF and how to set other options that affect the conversion from PostScript. In a PostScript file, DSC comments contain information about the file (such as the originating application, the creation date, and the page orientation) and provide structure for page descriptions in the file (such as beginning and ending statements for a prologue section). DSC comments can be useful when your document is going to print or press. For more information, see the documents on the Adobe PDF Technology Center at www.adobe.com/go/learn_acr_pdftechnology_en (PDF, English only). Note: The ASCII Format option has been removed from Distiller, but is still available as a Distiller parameter. Allow PostScript File To Override Adobe PDF Settings Uses settings stored in a PostScript file rather than the current PDF settings file. For more information about customizing PDF settings, see the SDK information on the Acrobat Developer Center at www.adobe.com/go/learn_acr_devcenter_en (PDF, English only). Allow PostScript XObjects PostScript XObjects store fragments of PostScript code to be used when a PDF is printed on a PostScript printer. Use only in controlled workflows where there is no other option. Available when the Standard or Smallest File Size is selected from the Default Settings menu. Convert Gradients To Smooth Shades Converts blends to smooth shades for Acrobat 4.0 and later, improving quality and reducing file size of PDFs. Distiller converts gradients from Adobe Illustrator, Adobe InDesign, Adobe FreeHand®, CorelDraw, QuarkXPress, and Microsoft PowerPoint. Convert Smooth Lines To Curves Reduces the amount of control points used to build curves in CAD drawings, which results in smaller PDFs and faster on-screen rendering. Preserve Level 2 Copypage Semantics Uses the copypage operator defined in PostScript Level 2 rather than in Language Level 3 PostScript. If you have a PostScript file and select this option, a copypage operator copies the page. If this option is not selected, the equivalent of a showpage operation is executed, except that the graphics state is not reinitialized. Preserve Overprint Settings Retains any overprint settings in files being converted to PDF. Overprint settings create color by printing one ink on top of another ink. Overprinting Default Is Nonzero Overprinting Prevents overprinted objects with zero CMYK values from knocking out CMYK objects beneath them. Save Adobe PDF Settings Inside PDF File Embeds the settings file (.joboptions) used to create the PDF as an attachment. (To view the settings file, choose View > Show/Hide > Navigation Panes > Attachments in Acrobat.) Save Original JPEG Image In PDF If Possible Processes compressed JPEG images (images that are already compressed using DCT encoding) without recompressing them. When deselected, performance improves because only decompression, not recompression, occurs. Save Portable Job Ticket Inside PDF File Preserves a PostScript job ticket in a PDF. Job tickets describe the PostScript file and can be used later in a workflow or for printing the PDF. Use Prologue.ps and Epilogue.ps Sends a prologue and epilogue file with each job. These files can be used to add custom PostScript code that you want to have executed at the beginning or end of every PostScript job being converted. Sample Prologue.ps and Epilogue.ps files are located in (Windows) /Documents and Settings/All Users/Application Data/Adobe/Adobe PDF/Distiller/Data, (Vista) /Users/All Users/Adobe/Adobe PDF/Distiller/Data, or (Mac OS)/Library/Application Support/Adobe/Adobe PDF/Distiller/Data. In Windows Explorer, the Application Data folder is typically hidden; to make it visible, choose Tools > Folder Options, click the View tab, and select Show Hidden Files And Folders. Or, you can type the path into the Address text box. Last updated 10/11/2011
