roman font typically contains 256 characters – will increase the file size of the PDF document by

30k to 40k for PostScript Type 1 fonts, or more for TrueType fonts.

Subsetting fonts

Using the Enfocus Preflight Profile Editor, you can specify in a Preflight Profile whether a PDF

document should:

• Subset all fonts

• Subset all except the standard 14 fonts

• Subset all fonts except those that can be emulated for viewing

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.
