Font embedding and substitution
A font can be embedded only if it contains a setting by the font vendor that permits it to be embedded. Embedding prevents font substitution when
readers view or print the file, and ensures that readers see the text in its original font. Embedding increases file size only slightly, unless the
document uses CID fonts, a font format commonly used for Asian languages. You can embed or substitute fonts in Acrobat or when you export an
InDesign document to PDF.
You can embed the entire font, or just a subset of the characters used in the file.
When a font cannot be embedded due to the font vendor settings, and someone who opens or prints a PDF does not have access to the original
font, another font is temporarily substituted. To avoid problems, print only PDF files in which fonts can be embedded.
The Multiple Master typeface can stretch or condense to fit, to ensure that line and page breaks in the original document are maintained. The
substitution cannot always match the shape of the original characters, however, especially if the characters are unconventional ones, such as
script typefaces.
