I believe PDF is Postscript Level 3. When .ps files are sent to a
Postscript Level 3 RIP, the ps is converted to PDF in the
"normalizer". So
you can save some conversions by dropping a PDF directly into the hot
folder
on a PS3 RIP.
PDF is a superset to PostScript. There are things that PDF can do that
PostScript cannot. PDF is declarative whereas PostScript is
interpretive, and is also a programming language. They're really not
the same thing, by design. Adobe PostScript 3 RIPs that accept PDF
convert to PostScript then interpret but they have some special
handling both on the application side and the RIP side to deal with
unique PDF features like transparency. There are a couple of RIPs on
the market that rasterize PDF directly, Harlequin being one of them.
