if your editor is incapable of dealing with the postscript files and requires 
you to generate final artwork for them as pixel graphics then you will need to 
do that work for them. And they will need to do much better than "more than 
300dpi" as a spec for what format they require for artwork.

On Linux I just tested a couple of apps and Scribus seems to do a nice job of 
importing the pd.ps files exported by Pd 0.43.1 ... allowing you to export it as 
an image file in whatever resolution you like, in many formats ... but as Miller 
says there is a slight difference in font size that you may need to correct for 
in Pd if you are relying very much on font size for your layout.

Inkscape didn't cope with the pd.ps file very well at all, and the various PDF 
viewers I have were more limited in their saving options.

On other OSes there are also plenty of choices for layout apps which will read 
the pd.ps files properly.
