PDF/A documents are PDFs that follow a new standard for archiving electronic documents. They are self-contained for long-term reproducibility. The practical difference between creating a PDF and a PDF/A document is that the conversion settings should be “PDF/A-1b:2005 (CMYK)” or “PDF/A-1b:2005 (RGB)”. Also, all fonts must be embedded in the document and no additional security features are allowed.
