You can set PDF options when you export to PDF or when you create or edit PDF presets. Adobe PDF options are divided into categories. The categories are listed on the left side of the Export Adobe PDF dialog box, with the exception of the Standard and Compatibility options, which are at the top of the dialog box. When you’re exporting to PDF, changing any of the options causes “modified” to appear at the end of the preset name.

Standard

Specifies a PDF/X format for the file.

Compatibility

Specifies a PDF version for the file.

General

Specifies basic file options.

Compression

Specifies if artwork should be compressed and downsampled, and if so, which method and settings to use.

Marks and Bleeds

Specifies printer’s marks and the bleed and slug areas. Although the options are the same as in the Print dialog box, the calculations are subtly different because a PDF is not output to a known page size.

Output

Controls how colors and PDF/X output intent profiles are saved in the PDF file.

Advanced

Controls how fonts, OPI specifications, transparency flattening, and JDF instructions are saved in the PDF file.

Security

Adds security to the PDF file. Security options are not available when you create or edit a PDF preset.

Summary

Displays a summary of the current PDF settings. You can click the arrow next to a category (for example, General) to view individual settings. To save the summary as an ASCII text file, click Save Summary. A warning icon  appears with explanatory text if a setting in the selected preset cannot be honored and must be remapped. For example, if a preset specifies source profiles that don’t match the current color settings file, then the profiles specified by the color settings file will be used.
