Have you tried to export to IDML and reconstitute the file from xml code?
Have you investigated that particular font as to its type and age and whether or not it might be corrupt or ailing?
Michael, thanks for your reply. I was just going to check the font versions she is using against the ones I am using and stopped because I think she figured it out. It looks like it was a corrupt pdf preset. She made a new one with pretty much the same settings and everything looks good.
Not sure why that would happen but if someone has a theory I would like to hear it. And I had never had an issue with presets getting corrupt.
Okay, I was too quick to respond. My colleague exported the pdf a couple of more time and it appears that the problem is back. She said it only worked the first time.
I am going to push for her to clean her font cache as I am still leaning toward a font issue.
Michael, not sure what you mean by reconstitute the file from xml code.
