Options Document Structuring Conventions Default Page Size The Advanced job options specify Docment Structuring Conventions (DSC) comments to keep in an Adobe PDF file and 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. When working with the Advanced job options, it is helpful to have an understanding of the PostScript language and how it is translated to PDF. See the PostScript Language Reference, Third Edition (Addison-Wesley), the Portable Document Format Reference Manual, and Updates to the Portable Document Format Reference Manual. (The latter two documents are available on the Adobe Web site at www.adobe.com.) Options Preserve Level 2 copypage Semantics uses the copypage operator defined in LanguageLevel 2 PostScript rather than in LanguageLevel 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. Save Portable Job Ticket inside PDF File preserves a PostScript job ticket in a PDF file. The job ticket contains information about the PostScript file itself, such as page size, resolution, and trapping information, rather than about content. This information can be used later in a workow or for printing the PDF. Illustrator Overprint Mode enables CMYK colors to overprint. Convert Gradients to Smooth Shades converts blends to smooth shades for Acrobat 4.0 and later, making PDF files much smaller and potentially improving the quality of final output. Create Adobe PDF Online converts gradients from Adobe Illustrator, Macromedia Freehand, CorelDraw, Quark XPress, and Microsoft PowerPoint. ASCII Format creates the PDF file in ASCII text format. This option is useful if you want to open the file in a text editor to read or edit it, or if you want to send a PDF file across networks or mail gateways that don't support binary files. You should normally leave this unselected to save the file in binary format and create a smaller file. Document Structuring Conventions Resize Page and Center Artwork for EPS Files centers an EPS image and resizes the page to fit closely around the image. This option applies only to jobs that consist of a single EPS file. Preserve EPS Information from DSC retains information, such as the originating application and creation date for an EPS file. With this option deselected, the page is sized and centered based on the top left corner of the top left object and bottom right corner of the bottom right object on the page. Preserve OPI Comments retains information needed to replace a For Placement Only (FPO) image or comment with the high-resolution image located on servers that support OPI versions 1.3 and 2.0. For more information on Open Prepress Interface (OPI), see http://partners.adobe.com/public/developer/main.html. Preserve Document Information from DSC retains information such as the title, creation date, and time. When you open a PDF file in Acrobat, this information appears in the Document Properties Summary dialog box ( File > Document Properties > Summary). Default Page Size To specify a default page size, enter a width and height, and choose a unit of measure. The maximum size is 200-by-200 inches (45-by-45 inches for Acrobat 3.0 compatibility). Create Adobe PDF Online uses this page size only if a PostScript file does not specify a paper size. Typically, PostScript files include this information, except for EPS files, which give a bounding box size but not a page size.
