- Product
- Acrobat Distiller / Microsoft Publisher
- Device & OS
- not provided
- Scenario
- Converting a Microsoft Publisher document to a PDF file format.
- Observed behavior
- Acrobat Distiller fails the conversion process and throws an error indicating that the Calibri font is invalid, even if the user did not intentionally use Calibri in the document.
Ensure you have administrative privileges on your computer to install or repair system fonts, and verify that your Adobe Acrobat software is updated to the latest version.
Replace or Repair the Calibri Font in the Source Document
Identify and replace hidden instances of the Calibri font in your Publisher document to ensure Acrobat Distiller can process the file properly.
Acrobat Distiller often fails if a referenced font is corrupted, missing, or restricted by licensing. Even if you have not explicitly typed text in Calibri, it might be hiding in a master page, a default paragraph style, or an imported linked graphic.
Launch Microsoft Publisher and open the source document you are trying to convert.
Navigate to the 'Home' tab, click 'Find', and open the 'Font Substitution' menu to identify if Calibri is being called by the document.
Select 'Calibri' from the list of fonts in use and choose a universally supported, embedded font (like Arial or Times New Roman) to replace it.
Go to 'View' > 'Master Page' to inspect the background layout for any empty text boxes or default elements that might be using the Calibri font.

Modify Acrobat Distiller Font Settings
Adjust Distiller preferences so it ignores minor font embedding errors rather than canceling the entire PDF creation job.
Use Native PDF Export Instead of Distiller
Bypass older Acrobat Distiller checks entirely by utilizing modern built-in PDF export features, which handle fonts differently.

Frequently Asked Questions
Why does Acrobat Distiller say a font is invalid when I didn't type anything in Calibri?
The font may be embedded in a linked object (like an imported vector graphic or logo), set as the default font for an empty or invisible text box, or utilized in the document's master page layout settings.
How can I fix a corrupted Calibri font on my Windows computer?
You can repair the font by downloading a fresh copy of the Calibri font family or copying it from another PC, and installing it via the 'Fonts' section in your Windows Control Panel.
What does the 'Cancel job if font cannot be embedded' setting do?
This is a strict Distiller configuration that completely stops the PDF creation process if it encounters a font it cannot legally or technically embed. Disabling it allows the PDF to be created, though the missing font may be substituted with a default system font.
