Hi Gdcartwr,
We tried replicating your issue here on our end. Here are some screenshots that we have before and after sharing the PowerPoint file as PDF via Email as well as Save/Export/Print to PDF:
We noticed a slight difference with the typographical emphasis of the font after sending it as a PDF. Just to verify, are you experiencing the same change? If not, it will be better if you
can send screenshots of the changes that you're encountering when you're trying to
Save/Export/Print to PDF. In this way, we can further isolate your concern. For more information on how to add a screenshot in your reply/post, kindly check this article created
by Shawn 'Cmdr' Keene [MVP].
You can also share your file by uploading it on OneDrive. Then, get
a link, and post it in your reply. If you want to share it privately due to personal information that might be included on the file, you can reply to the private message that
we've sent. To view this, click your username or account name on the top right corner of this page. Then, click View private messages.
We look forward to your response and if you have additional questions, please let us know by replying to this thread. This way, we'll get notified and respond
back to you as soon as we can.
