|The key points to creating compliant PDF file:
- Embed ALL fonts
- NO bookmarks
- NO form fields
- NO hyperlinks
- NO page numbering
- PDF version 1.4 (acrobat 5) or higher
|Why is it important to create a GOOD, compliant PDF file?
In an effort to have published papers available to the public quicker, and to ensure that PDF files are
universally viewable by everyone, across all platforms, a set of PDF standards has been implemented. Although PDF files
are suppose to be inherently platform independent, in reality this is not the case. The single biggest problem is the
availability of the fonts used to create the PDF file versus the fonts available on the local machine used to view the file.
The simple solution is to embed ALL fonts used to create a document, within that document. Only then
does the PDF file become truly platform independent. There are, of course, other parameters which the PDF file must meet in
order to be a good PDF, and ensure a good viewing and printing experience for the viewing public.
|What's the single biggest problem when creating your PDF file?
FONT EMBEDDING. The most crucial part of creating a good PDF, is ensuring that EVERY font used in your document
is embedded. Most PDF creation programs will NOT (by default) embed the "base 14" (system) fonts, UNLESS you specifically tell it to do so.
In addition, the fonts you wish to embed, must reside on the system that you are using to create your PDF file.
Since there are so many different methods to create a PDF file, it is not possible to provide authors with the proper setup
instructions for every possible environment. Below are setup instructions for two of the more common distillers (Acrobat and
- Check your PDF creation tool for settings where you can indicate to "always embed all fonts".
- You may need to specifically tell your distiller to embed "base 14" and/or system fonts.
- Make sure the fonts you are using in your source document reside on the machine you are using to create your PDF file.
- If you cannot get a font to embed, it could be corrupted on your system, or it could be a "licensed" font that does not allow embedding - try using a different font.
|How to check if all fonts are embedded?
The simplest way to confirm if ALL your fonts are embedded is to view your PDF file with Adobe Acrobat Reader.
If you don't have Acrobat Reader installed on your system, go to the bottom of this page and click on the "Get Acrobat Reader" icon.
This free software is available for virtually every platform. Once installed, start the program and open your PDF file. Then choose
File > Properties and click on the Fonts tab. From here you can confirm that each font used in your file is embedded &
subsetted. After each font name, it should show "embedded". If it does not, then your file is NOT compliant.
