ADOBE ACROBAT 3D VERSION 8 103 User Guide See also "PDF/X- and PDF/A-compliant files" on page 512 "Find PostScript font names" on page 115 General panel options Use this panel to select a version of Acrobat for file compatibility and other file and device settings. (The panel appearance differs in Windows and Mac OS.) Compatibility Sets the compatibility level of the PDF. Use the most recent version (in this case, version 1.7) to include all the latest features and functionality. If you're creating PDFs that will be distributed widely, choose an earlier level, to ensure that all users can view and print the document. Object Level Compression Compresses structural information (such as bookmarks, accessibility, and noncom­ pressible objects), making this information neither visible or usable in Acrobat 5.0 or Reader 5.0. Tags Only compresses structural information; Off applies no compression. Auto-Rotate Pages Automatically rotates pages according to the direction of text. • Collectively By File Rotates all pages to match the orientation of the majority of text in the document. • Individually Rotates each page based on the orientation of the text on that page. • Off Prevents pages from rotating. Note: If Process DSC Comments is selected in the Advanced panel and if %%Viewing Orientation comments are included, these comments take precedence in determining page orientation. Binding Specifies whether to display a PDF with left-side or right-side binding. The Binding setting affects the display of pages in the Two-Up Continuous view and the display of thumbnails side by side. Resolution Use for PostScript files to emulate resolutions based on the printer they are printing to. Permitted values range from 72 to 4000. Use the default setting unless you plan to print the PDF on a specific printer while emulating the resolution defined in the original PostScript file. Note: Increasing the resolution setting increases file size and may slightly increase the time required to process some files. Pages Specifies which pages to convert to PDF. Embed Thumbnails Embeds a thumbnail preview for each page in the PDF, increasing the file size. Deselect this setting when users of Acrobat 5.0 and later will view and print the PDF; these versions generate thumbnails dynam­ ically each time you click the Pages panel of a PDF. Optimize For Fast Web View Restructures the file for faster access (page-at-a-time downloading, or byte serving) from web servers. This option compresses text and line art, overriding compression selections on the Images panel. Default Page Size Specifies the page size to use when one is not specified in the original file. EPS files give a bounding box size, not a page size. Images panel options The options in the Images panel specify compression and resampling for color, grayscale, and monochrome images. You may want to experiment with these options to find an appropriate balance between file size and image quality. The resolution setting for color and grayscale images should be 1.5 to 2 times the line screen ruling at which the file will be printed. The resolution for monochrome images should be the same as the output device, but be aware that saving a monochrome image at a resolution higher than 1500 dpi increases the file size without noticeably improving image quality. Images that will be magnified, such as maps, may require higher resolutions.
