Resolving PDF Font Rasterization & Accessibility Issues

Issue Overview

When converting Microsoft Word documents using custom or brand fonts (such as RedHat) to PDF, standard print/save methods may fail to properly map local font metadata. This causes Adobe Acrobat to rasterize the text layer into flattened images, resulting in screen reader failures (e.g., "Failed Alt Text" or missing text tags) and rendering the PDF non-compliant with accessibility standards.

Resolution Steps

1. Convert Document using the Acrobat Ribbon in Word

Step 1: Proper PDF Creation

Do not use File > Save As PDF or Print to PDF, as these methods flatten custom font layers.

  1. Open your document in Microsoft Word.
  2. Click the Acrobat tab in the top ribbon menu.
  3. Click Create PDF.
  4. Save the PDF file to your local device. The document will automatically open in Adobe Acrobat.

Verification: Text in the generated PDF remains selectable as vector text rather than a flattened image.

2. Configure Document Language Properties

Step 2: Document Properties Settings.

  1. Open the PDF in Adobe Acrobat Pro.
  2. Press Ctrl + D (Windows) or Cmd + D (Mac) to open Document Properties.
  3. Select the Advanced tab.
  4. Under Reading Options, set the Language dropdown to English (or your document's primary language).
  5. Click OK to save properties.

Verification: The primary language is explicitly defined under Document Properties > Advanced.

3. Run Accessibility Checker & Verify Reading Order

Step 3: Accessibility Validation.

  1. From the left sidebar or All Tools menu in Acrobat, select Prepare for Accessibility.
  2. Click Check for Accessibility > Start Checking.
  3. Review the Accessibility Check results panel.

Verification: The automated font/alt text error is cleared. Note that two standard manual check flags (Logical Reading Order and Color Contrast) will remain flagged for mandatory manual review to achieve full compliance.
