Hi,
My printer's 'ripped' proofs have blurs around the text – even on the paper areas there are 'swirls' of darker colour around the text. Where text is on backgrounds, the background also has swirls. Light-coloured text has blotches within the text. I used the Pre-Press Adobe default output and the PDFs I create, the text looks fine. The printers 'ripped' proofs though look awful. Does anyone know what to do (other than change printers – as it's too late)? Do I need to try a flattened export?

Yes try a pdf-x output, 1a will flatten the transparency. It does sound like there are issues with the rip not handling the transparency well. A flattened output should handle this better, also check you have got any text above any transparency, using layers.

if the printer's RIPped proof is produced from a RIP such as AGFA printdrive, then the reason that there are blurs is that the RIP has created rendred files which have the halftone patterns in them. When a rendered proof runs through an inkjet plotter, the halftone pattern can appear deceiving and almost like a moire, so to get around this a slight descreen and blur is put on by the proofing software to remove this pattern and makes the proof look more the printed product… in terms of colour. Yes, a side effect is that sharp vectors become slightly blurred.
If you still have doubts, ask your printer how their RIP generated the proof.
