Though I have not tried the PrPro re-sizing algorithms on Adobe Illustrator files, I find that (through CS3 anyway), the ones in Photoshop yield better results for my images, than doing the re-sizing in PrPro. I always use PS to re-size all AI work too, and Save_As .PSD's. Will have to experiment with the results on the AI's directly. May be a better job than with continuous-tone images. It's always nice to save a step and get great results at the same time.
