[Tex/LaTex] IEEEtran Export to PDF version 5 or above

lyxpdfpdftex

I'm writing a paper for an IEEE conference and am checking the PDF with PDFExpress. One of the errors that I'm getting is that the PDF version of my paper is under 5: (actually "version 5" in an Adobe Acrobat Reader version – editor)

PDF Version too low

I opened the file in Adobe Acrobat Reader and the file properties tell me that the PDF is version 4. (that's the Adobe Acrobat version – editor)

In LyX, I opened Document > Settings… and unchecked Use Hyperref Support under PDF Properties. I think these will take care of errors (1), (2) and (4) from the error report. However, I don't see a way to specify a PDF version.

I found this other solution, which made LyX complain about a missing \begin{document}.

So now I'm completely lost. How may I specify what PDF version to export the document in?

( Editors Note: The current version of the pdf open file format is 1.7 [2/7/2015]. Adobe Acrobat Reader is frequently, but not the only program, used to freely open pdf files. Createspace supports submittal pdf file in version 1.4 and below. They do not say they support pdf file format version 1.5 or above, which is this editors problem )

Technical specs:

  • LyX version 2.0.5.1
  • Mac OS X 10.7.5 (Lion)
  • MacTeX version: enter image description here

Best Answer

I think this problem can be solved using \pdfminorversion=4 before \begin{document}.
