You've been converting from a vector-graphics (in principle) format to a bit-mapped format, and the loss of quality you describe is inevitable in such conversions.
I'm deducing from the above that you don't have access to PDF-editing software (such as Adobe supplies -- at cost!)
It's not that I don't have the tools (I don't, though) but that I need to be able to alter them through scripts, taking a standard poster and changing/adding some text.
For example, imaging those posters outside newsagents that have a basic format but the text is changed daily to match the days headlines. I need to do that kind of thing.
One obstacle you may face (since this is a poster) is that the PDF be itself be bit-mapped graphics (partly or even wholly). If that's the case then I think you're stuck unless you can get access to the "source code" of the PDF.
Looking at the samples I have so far, which appear to have been created in Corel Draw, they're a mixture of vector and bitmap.
I've done this sort of thing a number of times, but (as I state above) the chance of success is very strongly contingent on what's in the PDF file (and therefore in the resulting PS file).
I have some control over the PDFs I start with, in as much as I can tell the designer what to do (albeit it'll have to be in words he understands and can deliver using something like Corel draw, so that might not be as helpful as it sounds).
If you want some off-list discussion for this particular case, drop me a line.
Thanks, I may do that. I'll play a bit more first, though. The offer is appreciated anyway!
