Solution 1Recommended

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.

1
Open Publisher

Launch Microsoft Publisher and open the source document you are trying to convert.

2
Check Font Substitution

Navigate to the 'Home' tab, click 'Find', and open the 'Font Substitution' menu to identify if Calibri is being called by the document.

3
Replace the Font

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.

4
Check Master Pages

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.

Replace or Repair the Calibri Font in the Source Document
Test the Conversion: Once the problematic font is replaced or removed, attempt to recreate the PDF using Distiller.

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.
