[OS X TeX] [OT] Embedding fonts in images

[Charilaos Skiadas]

Hope someone on this list can help me with what should be a pretty  
common problem, though not directly related to LaTeX. I have some  
images in pdf format, generated from R but perhaps that's not  
directly relevant. My publisher has asked me to embed all fonts,  
including things like Helvetica, Symbol, Zapf Dingbats etc, and I  
have so far been unable to do so. I tried ghostscript, with a call  
that looks like this:

gs -dNOPAUSE -dBATCH -sDEVICE=pdfwrite -sOutputFile=cha03fig03E.pdf - 
dCompatibilityLevel=1.3 -dSubsetFonts=true -dEmbedAllFonts=true - 
sFONTPATH=  cha03fig03.pdf

but that didn't seem to do it, Adobe Reader still reports Helvetica  
(or Times New Roman depending on which one I select to set in R) as  
not being embedded.

Any thoughts how to really force all fonts to be embedded? Google  
searching produced too many hits, which I did not find particularly  
enlightening.

Hoping this is something bleeding obvious to someone.

PS: Why on earth do publishers need fonts like Helvetica, Times etc  
embedded? Surely this is something they can easily do themselves, no?
