Acrobat 6 is likely placing the images into the final PDF as jpeg ( I
think ). If you are using PDFGraphics2D there is a constructor to aid you
in this
if
not, you will have to manually convert your images to jpeg. you can look
at the PDFGraphics2D class to see how this is done.

Probably your images are being subsampled or converted to jpeg.
I'm not aware that Acrobat 6 reuses images. Depending on what you are doing and
how you are doing it there are ways to optimize things. For example, if you are
merging fields using the same template, you can use a blank template
