7.36 Embedding versus subsetting fonts
Embedding fonts
Embedding a font implies that the entire font, i.e. every single character of the font, is copied into
your PDF document. This is particularly useful if your document needs to be displayed and printed
on a different computer, which may not have the same fonts installed.
Furthermore, if the entire font is embedded, you can still edit the text in the PDF document on a
computer that does not have the font installed. Note that embedding an entire font – a standard
roman font typically contains 256 characters – will increase the file size of the PDF document by
30 to 40 KB for PostScript Type 1 fonts, or more for TrueType fonts.
Some fonts cannot be embedded due to font licensing restrictions.
Subsetting fonts
Instead of embedding an entire font, you may want to embed only a subset of the font – i.e. the
characters of the font that are actually used in the text. Subsetting a font allows you to keep a file
as small as possible, which is recommended especially if you do not plan to add more text (and
hence more font characters) to the file. Note that when you combine two or more PDF documents
that have the same font subset, duplicate character information is not deleted from the merged
sets. This will result in a considerably larger file.
However, if it is not important that readers see the file in its original fonts, do not embed fonts at
all, and let Acrobat use substitute fonts when necessary. This will produce the smallest file possible.
Naturally, reducing file size will improve the file transferability.
Finding exact font names
A given font can have different names. And the name of the font which you see in your source
application is not necessarily the same as its “real” internal font name.
For example, the Adobe Type 1 font “Times” as you see it in your word processing or desktop
publishing program also has a PostScript name: “Times-Roman”. The same applies to its TrueType
counterpart “Times New Roman”: its name appears in Adobe Acrobat as “TimesNewRoman”
(without spaces).
Consequently, if you need to enter a font name manually in one of the dialog boxes of PitStop Pro,
it is important that you type the font name exactly as it is spelled in Adobe Acrobat . You can use
a PDF file to find the exact spelling of the name.
7.37 Placing PDF documents in PDF documents
About placing PDF documents in PDF documents
You can place pages of a PDF document in another PDF document. You may wish to do this, for
example, to do manual impositioning or to place multiple pages of one or more PDF documents
“n-up” on one page of another PDF document.
