Generated PDF is missing font will not upload to Amazon KDP

[JOHN37192225qfph]

I recented edited an existing PDF with Adobe online, for which I paid for the premium online version. After downloading the edited PDF, I opened it on Acrobat and it tells me a message like "cannot find or create font Athanles. Some text may not render correctly."

I tried to upload the PDF to KDP as I get an generic error. This does not happen with PDFs created with other applications.

Can you please tell me how to fix this issue?

Thank you!

John

Hi there

Hope you are doing well.

To verify that your Adobe PDF contains only the features, fonts, and formatting that you’ve specified, use the Preflight tool to inspect and, in certain cases, correct the document’s contents.
The Preflight tool analyzes the contents of a PDF to determine its validity for print production and a variety of other conditions that you can specify. Preflight inspects the file against a set of user-defined values, called preflight profiles. Depending on the profile, the preflight inspection can also correct certain errors. Preflight also runs checks and fixups on visible areas or certain objects and makes PDFs comply with various standards.

for detailed information please go through the help page https://adobe.ly/3yy1Kue and see if that works for you.

Amal
