In addition to what has been said you can use Object>Flatten Transparency. A lot of different outcomes may come out of transparency depending on the RIP engine your printer is using.

Do not trust the on-screen display of a print-ready .pdf. Ever. Seriously, any and all .pdf viewers have huge problems rendering print-ready .pdfs on-screen.

One of the common rendering errors is indeed with hairlines between areas of different opacity, or intersected by areas of different opacity or blending. Mostly, these hairlines are artefacts of the rendering you can safely ignore when sending your document to your printer.

To be absolutely sure, you can always zoom in on such a hairline--they will be just a single pixel wide, regardless of the zoom percentage. If the gap does scale with zooming, then there's something else amiss.

These rendering errors in most (if not all) common .pdf viewers has made me decide to never, ever send a print-ready file to a customer for final approval. They always approve a version optimised for screen display, while the printer receives the actual cPDF.

Easy solution, export artwork as a JPEG with maximum quality.
