I get similar situations depending on how I process.
Using fop to generate a PDF (default) from a .fo file works for JPEG.
Using fop to generate a PS file from a .fo file works too.
Using ghostscript (gs) to rework the first PDF file to a PDF file makes
the image chunky.
Using ps2pdf to change the PS file to PDF makes the image chunky.
Maybe not directly relevant to your situation, but I suggest to look if
generating PS makes something printable with the proper resolution.
