Output resolution of PDF

[Micha Feigin]

I'm trying to include equations created in lyx/latex inside a scribus poster (The scribus 
plugin doesn't seem to do what I want). The output resolution is too low though (seems to 
be 72dpi) and the fonts look really bad. Is there a way to get latex to output the 
document at a higher resolution? (I'm using the palatino font at the moment)

Thanks
