Any RIP that will pass the Altona or Ghent Work Group test suites will work just fine. If you don't want to buy a RIP but need something to generate "high res" bitmaps from PDF's then use callas pdfToolbox Server to convert each page to a high res CMYK TIFF.
A Harlequin low res RIP (up to 1500 dpi) will work just fine and make bitmaps or direct drive the printer. Just about any modern RIP will work great.
To me it sounds like a lot of "Bachelor of Science" if you get my drift... Feel free to contact me offline if you like.
