Although the default PDF presets are based on best practices, you may discover that your workflow, or perhaps your printer’s workflow, requires specialized PDF settings that aren’t available via any of the built‑in presets. If this is the case, you or your service provider can create custom presets.
To create a new preset, click New. If you want to base the new preset on an existing preset, select the preset first.
To edit an existing custom preset, select the preset and click Edit. (You cannot edit the default presets.)
Alternatively, you can create a custom preset when you save a PDF file by clicking Save Preset at the bottom of the Save Adobe PDF dialog box.
PDF presets are stored in .joboptions files located in /Documents and Settings/All Users/Documents/Adobe PDF/Settings (Windows) or /Library/Application Support/Adobe PDF/Settings (Mac OS). All custom presets you save in these locations are available in your other Creative Suite applications.
