PDF Specification

The PDF Specification describes the required electronic format. The specifications are required versions of the PDF standard and must be followed in order for the data file to be processed. You can choose the specification from 1.3 to 1.7. It’s recommended to keep the default setting (auto) if it’s not entirely clear what the PDF Specification is.
