Dear Sam,
I am a bit surprised,
because this is normal if you make a screen hardcopy with 72 dpi.
Why don't you save your vectorgraphic into postscript?

I'd guess Velovect could be improved by add a Thick keyword
to it. That might be just the thing to improve resolution
of JPEG images. It would probably take about 5 seconds to
do.
