You will likely get better responses from others, but I think that 
you're use of Scribus to then have output as a jpeg is not the way to go.
Is there some reason you're not exporting to PDF? -- the whole point of 
making PDFs is to scale to whatever size you want.

About the only kind of image that would theoretically work (and Scribus 
can't do) is an SVG.
