Font, OPI, and flattening options for PDFs

You can set the following options in the Advanced area of the Export Adobe PDF dialog box.

Subset Fonts When Percent Of Characters Used Is Less Than
Sets the threshold for embedding complete fonts based on how many of the font’s characters are used in the document. If the percentage of characters used in the document for any given font is exceeded, then that specific font is completely embedded. Otherwise, the font is subsetted. Embedding complete fonts increases file size, but if you want to make sure you completely embed all fonts, enter 0 (zero). You can also set a threshold in the General Preferences dialog box to trigger font subsetting based on the number of glyphs a font contains.

OPI
Lets you selectively omit different imported graphics types when sending image data to a printer or file, leaving only the OPI links (comments) for later handling by an OPI server.

Preset
If Compatibility (in the General area of the dialog box) is set to Acrobat 4 (PDF 1.3), you can specify a preset (or set of options) for flattening transparency. These options are only used when exporting spreads with transparency in artwork.
Note: Acrobat 5 (PDF 1.4) and later automatically preserve transparency in artwork. As a result, the Preset and Custom options are not available for these levels of compatibility.

Ignore Spread Overrides
Applies the flattener settings to all spreads in a document or book, overriding the flattener preset on an individual spread.

Create JDF File Using Acrobat
Creates a Job Definition Format (JDF) file and starts Acrobat Professional for processing the JDF file. A job definition in Acrobat contains references to the files to be printed as well as instructions and information for prepress service providers at the production site. This option is only available if Acrobat 7.0 Professional or later is installed on your machine. For more information, see Acrobat Help.
