document does not specify the trapped state, the value provided here is used. If your workflow requires that the

PDF compatibility levels
When you create PDFs, you decide which PDF version to use. You can change the PDF version by switching to a
different preset or choosing a compatibility option when you save as PDF or edit a PDF preset.
Generally, unless there’s a specific need for backward compatibility, use the most recent version (in this case, version
1.7). The latest version includes all the newest features and functionality. However, if you’re creating documents that
will be distributed widely, consider choosing Acrobat 6.0 (PDF 1.5) or Acrobat 7.0 (PDF 1.6). Using one of these
versions ensures that all users can view and print the document.
The following table compares some of the functionality in PDFs created using the different compatibility settings.
