Dear Authors,
Please create pdf with:
ps2pdf -dMaxSubsetPct=100 -dCompatibilityLevel=1.3 \
-dSubsetFonts=true -dEmbedAllFonts=true \
-dAutoFilterColorImages=false \
-dAutoFilterGrayImages=false \
-dColorImageFilter=/FlateEncode \
-dGrayImageFilter=/FlateEncode \
-dMonoImageFilter=/FlateEncode myFile.ps
This will include all fonts, make sure figures are compressed correctly, etc.
Thanks
