Embedding fonts in Adobe PDF files
PDFWriter can embed Roman Type 1, TrueType, and base fonts in an Adobe PDF file.This
ensures that the original font is used for display and printing on computers that do not
have the font installed. Adobe Type Manager (ATM) must be installed and loaded as a
control panel for PDFWriter to be able to embed Type 1 fonts. PDFWriter cannot embed
Asian fonts.
PDFWriter embeds only the set of characters used in the file if fewer than 35% of the
characters in a font are used in the file. (Standard Roman fonts contain 256 characters;
35% of a Roman font is approximately 90 characters.) You cannot change this threshold in
PDFWriter. If you need more precise control, see
page 57 for information on embedding fonts with Distiller.
If you do not embed fonts in a PDF file and a user opens the file on a system that does not
have the file's fonts, Acrobat temporarily substitutes fonts. For Roman text, Acrobat uses
serif and sans serif Multiple Master fonts to simulate the original font. For Asian text,
Acrobat uses fonts from the installed Asian Language Kit or from similar fonts on the user's
system. See "About font embedding and substitution" on page 56
embed a font and the user has that font on their system, they can edit the text in the PDF
file.
An embedded font typically adds about 30K to 40K to a PDF file. If it is not important that
readers see the file in its original fonts, do not embed fonts. Let Acrobat use substitute
fonts when necessary.This will produce the smallest file possible.
To help you decide which fonts to embed in a PDF file, you can get a preview of how
the substituted fonts will look in the file. See
fonts" on page 57.
To modify which fonts are embedded in an Adobe PDF file:
1 Do one of the following:
In a Windows application, choose File > Print (Print Setup in some applications), select
•
Acrobat PDFWriter from the Printer Name menu, and click Properties (Setup in some
applications).This will change the settings for the open file and for other files you
convert to Adobe PDF during the current session with this application.
