To trap documents using the InDesign built‑in engine, you need a PPD that supports separations.

To trap documents using the Adobe In‑RIP Trapping engine, you need the following software and hardware:

• An Adobe PostScript Level 2 or later output device that uses a RIP that supports Adobe In‑RIP Trapping. To find out if a PostScript output device supports Adobe In‑RIP Trapping, contact the manufacturer or your prepress service provider.

• A PPD (PostScript Printer Description) file for a printer that supports Adobe In‑RIP Trapping. You must select this PPD when you install the printer.
