To produce in‑RIP separations,
you need the following software and hardware:
-
A PPD file that supports in‑RIP separations.
-
Any PostScript 3 output device, or a PostScript Level 2 device
whose RIP supports in‑RIP separations. If the document contains
duotones from Photoshop 5.0 or
later, a PostScript 3 device is required to generate in‑RIP separations.
Note: Depending on the prepress software available,
a service provider may be able to perform such prepress activities
as trapping, imposition, separating, and OPI replacement at the
output device’s RIP. Therefore, your service provider may prefer
to receive a composite PostScript file of the document optimized
for in‑RIP separations, rather than a preseparated PostScript file.
