For detailed information on PDF structure, see the documents on the Adobe PDF Technology Center at
glish only). If you have advanced knowledge of the PDF file
format, examine the internal structure of the PDF and its fonts for technical reasons for a preflight mismatch. Preflight
includes three options for in-depth inspection of a PDF. Technically skilled users can use these tools to analyze the
