Description
This 'exchange standard' format is based on Adobe's PDF specification and a subset of the PDF specification. This version was an updated version of PDF/X-1:1999, and was based on PDF 1.3. It was superseded in 2003 by PDF/X-1a and PDF/X-3, at which point it was recommended that PDF/X-1 no longer be used. PDF/X-1 is the only PDF/X standard permitting encryption.
