The target document should be PDF v1.4. PDF is generally not suited for long term preservation. The PDF format may contain resources (such as fonts) that may not exist on the viewing machine. Hence, font substitution may occur resulting in a document that may not look exactly like the original version. | |
| 3 | PdfA |
The target document should be PDF/A. PDF/A is a subset of PDF obtained by leaving out PDF features not suited to long-term archiving. The resulting document is 100 percent self contained where all of the information necessary for displaying the document in the same manner every time is embedded in the file. Saving with PDF/A document type may result in larger output file sizes. |
