I'm using illustrator to create a piece of artwork. I've used several transparent layers (small circles). Since I'm using a transparent effect, do I need to rastarize or flatten it?

I tried flattening but those transparent circles changed back to their original color (back to 100%, no more transparency).

This is for commercial printer to make 1000 copies of it. I'm sending the files in PDF.

If you are sending files to Press as a PDF you needn't worry about transparency.

Simply save as a PDF/X-1a file and send it. All the transparency will be adjusted (flattened) as needed when saving the PDF. In general, there's nothing you need to manually do before saving a PDF/X-1a file.

Flattening is sometimes needed for special circumstances, such as providing EPS files (but generally not PDFs). Rasterizing more of a last resort in terms of production. – Scott Jul 7 '13 at 9:24
