Printing color PDFs (Adobe Acrobat Pro)

Acrobat supports host-based separations and in-RIP separations. The main difference between them is where the separations are created—at the host computer (the system using Acrobat and the printer driver) or at the output device’s RIP.

For host-based separations, Acrobat creates PostScript information for each of the separations required for the document and sends that information to the output device. For in-RIP separations, the work of separating a file is performed by the RIP. This method often takes less time than creating host-based separations, but it requires a PostScript 3 output device with in-RIP separation capability. To produce in-RIP separations, you need a PPD file that supports in-RIP separations, and any PostScript 3 output device or a PostScript Level 2 device whose RIP supports in-RIP separations.
