Export to PDF causes fringing around transparent PNGs only in Acrobat
If I export to PDF from Keynote '09 using the "Best" setting, I'm getting black fringing around solid elements in a transparent PNG that was placed in the original keynote doc. This fringing does not occur when the PDF is viewed in Preview. Any suggestions on how to remove the fringing?
Example is here: http://i.imgur.com/3QXGf.jpg
Thanks in advance for the help.
