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 email@example.com
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.
When adding a figure to your publication, you might want to remove the undesired white-border off your figures. I believe that the best way is to create figures without the border if it is possible. In MATLAB, I think you can do so. However, if you have the figures already, you might want to have a program to remove the borders automatically, wisely and controllably. I developed a toolbox in MATLAB for this purpose. Please refer to the URL below.
