The (main) problem with using the Sun renderer (or the JPEDAL one, for that
matter) in this particular instance is that it/they render to RGB. In order to
do separations you need to render to a Device-N planar surface (aka CMYK +
spots).
Secondarily, of course, is the problem that you end up with a raster result -
but that's not necessary as bad if you have high enough resolution.

Why don't you go get the pdfrenderer and modify that?
https://pdf-renderer.dev.java.net/
I just got
that a few days ago and it was pretty easy to remove the gui
junk and now, by default for testing, it saves the pdf as a series
of jpeg's but it could just as easily be bmp files which would
be easy to "separate" or otherwise manipulate.
I'm hoping to get time to modify it to run on j2me but if
not, at least it leta me play with various rendering options
to reformat for smaller screens etc.
I personally am considering that java version as my normal viewer since
it seems to be faster and easier to use than Reader as well as being
open source. Someone just
sent me 3 pdf files that I have open and now firefox keeps
hanging ( memory shortages stupid OS contention? don't know
and don't care ). This happens all the time when people write
apps predicated on the mantra, " but memory is cheap" etc.
An app is not flexible if the "flexible" code depletes all the
system resources due to its flexibility and with open source I have
some chance of fixing that.
