When a font is substituted, the resulting text may look similar, but it's not the same. The substituted font may have different glyphs, spacing, and kerning, which can affect the overall appearance and readability of the text. This can be particularly problematic in situations where precise typography is crucial, such as in:
When a document is created, the text is linked to a specific font file (e.g., Times New Roman Bold ). If that file is not installed on the computer opening the document, the software cannot display the text as intended. To ensure the document remains readable, the software automatically swaps the missing font with a "substitute" font—usually a standard system font like Arial or Courier.

To ensure that "Font Substitution Will Occur" remains a warning you never see, implement these protocols: When a font is substituted, the resulting text

Or you open the file on a client's laptop. Or you send the final proof to the press house. In that moment, a small, grey dialog box appears—or worse, doesn't appear—with the silent verdict: "Font substitution will occur."
To understand the risk, you have to understand the mechanics. When you create a document on Computer A, you use fonts installed on that system. When you move that document to Computer B—perhaps a print shop or a colleague's laptop—the software looks for those exact fonts.
The file was created on a different machine with fonts you don't have installed.
