About font embedding and substitution
A font is 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 double-byte fonts--a font format commonly used for
Asian languages.
You can embed the entire font, or just a subset of the characters used in the file.
Subsetting ensures that your fonts and font metrics are used at print time by creating a
custom font name. That way, your version of Adobe Garamond
®
, not your service
provider's version, can always be used by the service provider for viewing and printing.
When Acrobat cannot embed a font due to the font vendor's settings, and someone who
opens or prints an Adobe PDF file does not have access to the original font, a Multiple
Master typeface is temporarily substituted: AdobeSerifMM for a missing serif font, and
AdobeSansMM for a missing sans serif font.
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. (For Asian text, Acrobat uses fonts from the installed Asian
language kit or from similar fonts on the user's system. Fonts from some languages or
with unknown encodings cannot be substituted; in these cases, the text appears as bullets
in the file.)
If characters are unconventional (left), the substitution font will not match (right).
Acrobat can embed Roman Type 1 and TrueType fonts in an Adobe PDF file to prevent
font substitution if users don't have that font on their system or available to their printer.
Type 1 and TrueType fonts can be embedded if they are included in the PostScript file, or
are available in one of the font locations that Distiller monitors and not restricted from
embedding.
Note: In some cases, TrueType fonts that have gone through a PostScript driver can no
longer be searched, copied, cut, or pasted. To minimize this problem, use Acrobat on the
same system on which the PostScript file was created, and make sure that the TrueType
fonts used in the file are available on the system.
