If you're just adding a flat background colour you can simulate overprinting by adding the background colour to the type:

Say the type is 100%K, while the background is 10%cyan and 5% magenta --- set the type ac c10 m5 y0 k100.

To post-process it, I'd either use PitStop, or just make a process plan in our RIP --- perhaps Ghostscript could do something similar.

There should be a special which can be added to the .pdf to set overprinting for a block of type, but I've always been able to avoid the need to look that up.
