Solved: pdfExpress verification gives some errors

August 5, 2011 Leave a comment

My paper did not pass the pdfExpress verification due to the error:

Error Font Helvetica is not embedded (111x)

Here we follow the process from the submission homepage:

If you are using the conference template in its Winword version and still get errors (or no answers) from pdfExpress, try this procedure:
1) Please check the top margin of the the first page. it MUST be 2.5 cm; for OTHER pages it must be 1.9 (cm)
2) Generate the pdf file
3) Then you have to embed the fonts. You can do that either
3.1) by using acrobat professional or
3.2) using the line command

gs -dSAFER -dNOPLATFONTS -dNOPAUSE -dBATCH -sDEVICE=pdfwrite -sPAPERSIZE=letter -dCompatibilityLevel=1.4 -dPDFSETTINGS=/printer -dCompatibilityLevel=1.4 -dMaxSubsetPct=100 -dSubsetFonts=true -dEmbedAllFonts=true -sOutputFile=OUTPUT.pdf -f INPUT.pdf

where INPUT.pdf is the pdf source file, OUTPUT.pdf is the output file to be submitted with the fonts embedded and gs is the ghost-script executable command.
If this does not work, or you have other pdfExpress problems, please contact Dr. Romolo Camplani at

However, after trying such a method, the pdf is rejected from the submission website. So, we still have to put the output file to pdfExpress to verify again, and of course you can now expect no error. Then you can proceed to submit the pdfExpress-verified pdf to IJCNN, and the file is PID1839743.pdf whose content is identically the same as ClosedFormDcsGMM_IJCNN_final_added2.tex.

  • single figure: epstopdf figure.eps –> this works both on Linux [link] and Windows
  • multiple figures on Ubuntu–this will run epstopdf on all .eps files in current directory and all subdirectories:

blahblah$ find . -name “*.eps” -exec epstopdf {} \;
