This may also help:

Try increasing the image resolution in the same dialog. By default,
Distiller uses a low resolution. Set it to at least 600 dpi (unless your
image resolutions are lower).

Also, manipulate your images in an image tool like Photoshop. Set your DPI
and sizes there. Save the image in a non-lossy compressed format (like
TIFF, not JPG or GIF). Then import the new image into FrameMaker and choose
the same settings (i.e. don't let FrameMaker manipulate the image). You'll
get better quality output that way.

Note: If your final destination is grayscale (e.g, hardcopy), then also
convert your image to grayscale in your image software.

The trick is to let each piece of software do what it does best. You'd
never want to use Photoshop as a word processor. So, don't use FrameMaker
to manipulate images.

I hope this helps. Obviously, I just went through the same problem.

Hi Mark,

You've got two problems with almost the same solution, I guess. I think
it's in the Menu Distiller > Job Options > Compression Tab. Take a good
look at the settings on both machines, especially at the graphics
settings. I think the big files come from low compression and the fuzzy
images from high compression.
Hope this works.
