gs -r720 -sDEVICE=tiff32nc -sOutputFile=out.tif input.pdf

If this isn't a single page document then add -dFirstPage= and -
dLastPage=

720 is the default resolution for pdfwrite, but you can fiddle with it 
until you see something correctly sized for your output.

There's no way to save immediately in an image format I'm afraid. But 
that shouoldn't matter. One thing that just occured to me is that its 
possible that the original is a JPEG image, and you have colour images 
set for JPEG compression, which would apply a second set of DCT losses.

Ah, no, I see you are using Flate.

Well, not likely to be different in the working code.

Can you post a sample PDF somewhere public ?
