Solution 1Recommended

Install or Repair the Missing Font

The most direct fix is to ensure the specific font causing the error is properly installed and accessible on your operating system.

Adobe Distiller needs access to all the fonts used in your source document to correctly generate a PDF. If a font like OpenSans-Bold is missing, uninstalled, or corrupted, the Distiller will throw an invalidfont error. Reinstalling the font system-wide usually resolves this.

1
Download the required font

Acquire the missing font file (e.g., OpenSans-Bold.ttf). For Open Sans, you can download it for free from the Google Fonts website.

2
Install the font

Right-click the downloaded font file and select 'Install' or 'Install for all users'.

3
Restart the application

Close the source application (such as Microsoft Word or InDesign) entirely so it can detect the newly installed font.

4
Retry PDF creation

Reopen your document and try printing to Adobe PDF or running Adobe Distiller again.

Install or Repair the Missing Font
Font Availability: Once the font is correctly installed at the system level, Adobe Distiller will be able to embed it properly into the final PDF.

Frequently Asked Questions

What causes the 'invalidfont' error in PDF Distiller?

This error occurs when the source document contains a font that is not installed on your system, is corrupted, or has licensing restrictions that prevent it from being embedded into a PDF file.

Where can I find the Open Sans font to download?

Open Sans is a free, open-source font. You can download the complete font family securely directly from the Google Fonts website.

Can I ignore font errors in Adobe Acrobat?

Yes, you can configure Adobe Distiller settings to continue generating the PDF even if a font fails to embed. However, the resulting document will substitute the missing font with a default one, potentially altering your document's layout and design.

Does the 'invalidfont' error happen with standard system fonts?

Rarely. It mostly affects custom, downloaded, or third-party fonts (like OpenSans-Bold) that are either missing from your local font directory or lack the proper embedding permissions.
