Embedded Fonts

What is Font Embedding?

When you create a document in an application like Adobe InDesign, Microsoft Word, or Canva, the software references specific font files installed on your local computer to display text.

When exporting a PDF for print, you must embed these font programs inside the PDF container. Embedding copies the vector shapes of the characters into the PDF itself, ensuring that any other computer or printing press can render the text without needing the original font file installed.

The Print Risk: Missing Fonts and Layout Shifts

If a PDF is sent to a print shop with unembedded fonts:

• Font Substitution: The prepress computer or RIP (Raster Image Processor) will substitute the missing font with a default system font (like Courier, Arial, or Times New Roman).
• Layout Mismatch: System fonts have different character widths and heights. When substituted, text lines can overflow, words can overlap, paragraphs can break onto new pages, and special symbols can convert to gibberish.
• Missing Text: In some cases, characters might not render at all, leaving blank spaces where names or pricing should be.

How Filecheck Audits Font Embedding

Unembedded fonts are the #1 reason print orders are rejected or delayed. Filecheck automates this check:

1. Font Dictionary Check: We inspect the internal PDF structure to verify that every referenced font contains an embedded descriptor stream.
2. Flag and Reject: If any font is missing, Filecheck flags a warning or blocks the upload, prompting the customer to re-export their file.
3. Outlining Support: For products that require extreme safety, Filecheck can verify that text has been converted to vector shapes (outlines), completely bypassing the need for font embedding.
