Update and Repair Adobe Acrobat Installation
Outdated or corrupted Adobe Acrobat installations often cause font rendering and substitution issues.
Software glitches within Adobe Acrobat can sometimes prevent it from correctly reading embedded fonts or local system fonts. Updating and repairing the software ensures all rendering components are intact.
Open Adobe Acrobat, click on the 'Help' menu at the top, and select 'Check for Updates'. Follow the on-screen prompts to install any available updates.
Navigate to the 'Help' menu again and click on 'Repair Installation'. Acrobat will scan for and fix any corrupted or missing program files.
Once the repair process finishes, restart your Windows computer to apply the changes, then open the PDF to check the font.
Reinstall the Affected System Fonts
Missing or corrupted Arial system fonts on the specific Windows machine can cause Acrobat to fall back to SansMM.
Adjust Acrobat Display and Protected Mode Settings
Hardware acceleration or strict security modes in Acrobat might interfere with how fonts are drawn on the screen.

Frequently Asked Questions
Why does Adobe Acrobat substitute fonts with SansMM?
When Acrobat cannot locate the original font (such as ArialMT) embedded in the PDF document or installed locally on the computer's system, it uses a default Multiple Master (MM) font like SansMM as a fallback. This ensures the text remains readable, even if it looks different.
How can I ensure my fonts always display correctly in PDFs?
When creating or exporting a PDF from your authoring software (like Word or InDesign), ensure that the option to 'Embed all fonts' is checked in your export settings. This bundles the exact font data within the document, so it renders identically on every device.
Can an outdated graphics driver cause font rendering issues in Acrobat?
Yes. If you have 'Use 2D graphics acceleration' enabled in Acrobat's Page Display preferences, the software relies on your graphics card to draw text. An outdated or corrupted graphics driver can cause fonts to display incorrectly or appear glitchy.
