One way to achieve this by hand:

* Export the file as .ps (instead of directly to .pdf)
* use the command:
ps2pdf -sPAPERSIZE=a4 \
-dMaxSubsetPct=100 -dCompatibilityLevel=1.3 \
-dSubsetFonts=true -dEmbedAllFonts=true \
-dAutoFilterColorImages=false \
-dAutoFilterGrayImages=false \
-dColorImageFilter=/FlateEncode \
-dGrayImageFilter=/FlateEncode \
-dMonoImageFilter=/FlateEncode \
myfile.ps myfile.pdf
to convert the ps to pdf in perfect quality.

Would be nice, if texmacs contained this as an option. (seems, like it
is using ps2pdf internally anyway, so it would just be a matter of
setting the options)
