This makes sure that the file can be viewed and printed as it was created by the designer. There are two mechanisms to include fonts in a PDF:. Keep in mind that font foundries can forbid font embedding for certain typefaces through their end-user license agreement.
In TrueType and OpenType fonts, they can add this restriction in the font data. Applications that properly honor the licensing policy of such a font will not embed it in a PDF. Only a few type foundries actually release fonts with such severe restrictions, but they do exist. If certain fonts are missing from the PDF file, Adobe Acrobat, and Adobe Reader will automatically try to emulate the missing font by using one of the Multiple Master fonts that are built into these programs.
The Multiple Master fonts that are used for this are:. Another important aspect of font handling is encoding. This refers to the mapping of a character code to a particular glyph character shape description.
Each font in a PDF uses a specific type of encoding, either a standard or a custom one. The following types of encoding are supported by the PDF file format:. Obviously there are other tools that can provide an overview of all fonts, such as for instance the Enfocus PitStop plug-in.
Acrobat Distiller offers an option to automatically add missing fonts to PostScript files it has to process. In the font locations menu, the user can define several folders that have to be searched for fonts that are missing in the PostScript file.
Distiller only needs the printer fonts, it does not need the screen fonts. Older versions of Adobe Acrobat Acrobat 3. From Acrobat 4. In fact, it is a good idea to actually always embed these fonts as well.
Instead, we got another restriction: if the licensing policy of a TrueType forbids the font to be included in a file, Distiller 4 and later will respect this restriction and will not embed the font. It is possible to only include those characters of a font that are actually used in the publication.
Usually you can specify that font subsetting needs to be used as soon as a certain percentage of the character set of a font is used. Sometimes it can be practical to convert all fonts within a PDF to outlines. You should be aware that outlining fonts affects the quality of the type: at smaller type sizes the output quality will be slightly inferior because font hinting is gone and small type may also fatten up a little.
This will only outline text on pages that have transparency in them so the trick is to add a transparent object to each page either using a watermark or using PitStop Professional. You can find a discussion and sample screenshots about this trick in this thread. You actually cannot extract a font from a PDF, not even if the font is fully embedded.
There are two reasons why this is not feasible:. I am not aware of any font extraction tools but if you come across one, the above reasons should make it clear that these utilities are to be avoided. In order to minimize surprises with fonts in PDF, try following these guidelines:. For multi-user document collaboration, identify reviewers by name or email address and save annotation settings through custom callbacks default settings display GUEST as the reviewer name for all comments.

When you save a file as a PDF , you are essentially packaging all of the components of your design into a single file. Think font information, color information, and any other settings you have used. This ensures that whoever is viewing your file on their own device is able to view it as you intended. Designers often use programs such as Adobe InDesign or Adobe Illustrator, both of which will create a reference to the fonts you use, but neither stores them in the file itself. When the software needs font information, it is able to locate it on your computer where it originally pulled it from.
When this happens, the font will be replaced with another, completely changing the look of your design. This process is known as embedding.
