Hi Larry,
Thanks, I've just checked with Neha and I did see a difference on your particular file.
However, we tried to convert a presentation to PDF and did not see a difference. Additionally, as you mention that it's improved, we suggest copying all pre-16.9 presentations to a new file if you would like to export it as a PDF.
We also suggest providing feedback by clicking on the Smiley
face on your PowerPoint app to let the related team know.
Meanwhile, have you tried using some sample images that is not confidential and let us know the results? This will hopefully make it easier for you to share with us.
We tried a few different images but can't see the difference, probably because it's already subtle enough, given that it's created on 16.9.
@MrsGenna,
We noticed that you posted in a few different threads regarding the issue, and based on your description, it seems like the issue is with image resolution inside PowerPoint itself and when printing.
If this it the case, we suggest posting a new thread so that we can focus on the issue individually. If you are having issues with images when converting to PDF, you're welcome to provide a screenshot and refer to the suggestions on this thread in order
to help us narrow down the issue.
Regards,
Sheen
