Embed Fonts Properly

Font consistency is one of the most critical factors in ensuring a PDF renders correctly across different systems. Missing or substituted fonts can lead to spacing shifts, incorrect character mapping, and visual inaccuracies.

Best Practices

• Fully embed all fonts (not just subsets) within the PDF so that they render identically on all systems and platforms.
• Use Unicode-compliant fonts to ensure correct character encoding and extraction, especially for multilingual or regulatory content.
• Avoid rare, custom, or non-standard encodings, which may cause text corruption or prevent proper comparison.
• Perform a font check using pre-flight tools to confirm that all fonts are correctly embedded and mapped.

Why this matters for proofing?

Improperly embedded or non-standard fonts can cause garbled text during extraction or alter the visual appearance of critical content. Proper embedding ensures consistent rendering, accurate text recognition, and reliable automated verification.
