Subject: Dithering (off-topic)

Good evening.

I apologize to ask a little off-topic question, but I don't know where 
to ask (and it is closely related to TeX and PDF).

I typeset a church bulleting. It is printed on a laserjet printer (600 
dpi), and then copied on a copy machine. As for letters, all is right. 
But figures (photos) are this way spoiled. I guess it would help either 
to force PDF to print the figures in some very low resolution (150 dpi), 
or (probably better) to dither the figures and include them in PNG 
(instead of ordinary JPEG). Can some of you tell me how to do it? I 
tried ImageMagick's convert to dither the photos, but outcomes were 
really poor. Is there some good free software for this (in the best case 
in Linux)? Or can I do it some way in PDF?

Many thanks for any hint.
Michal Kvasnicka
