Kill White Lines in Acrobat
If you export a PDF and view the PDF in Acrobat, and you see a white line around an item in the PDF, you can make that line go away by turning off “Smooth Line Art” in Acrobat’s Page Display preferences. The white line usually doesn’t print, but you and your clients may feel better not seeing the white line.

As far as I know, some white lines around objects may indicate some transparency problems., so printing or exporting to PDF with native transparency can also solve this problem.
