Subsetting Type fonts

You can reduce file size by subsetting Type 1 fonts. A font is made up of many characters. If you use only a smaller number of characters (for example English characters A to E), you can create a subset of Type 1 fonts, reducing the size of a file. You can also include a percentage of fonts used. For example, you can create a subset of 50 percent of fonts. If the number of characters used in the document exceeds 50 percent, the whole set of characters is embedded. If the number of characters used in the document is less than 50 percent, only the percentage of characters used is embedded.

To create a subset of Type 1 fonts

1 Click File, Publish To PDF.

2 Click the Objects tab.

3 Enable the Subset Type 1 Fonts check box.

• If you create a subset of Type 1 fonts, you should not edit or correct the PDF file at the service bureau using Acrobat Exchange, since the characters you add when editing may not be present in the file.
