Hi, Andi.
Assuming high enough resolution, your original image--which was very
nice, by the way--was just fine for conventional printing (usually
offset lithography). Conventional printing methods can take advantage
of the full range of tones in your image.
Copy machines, on the other hand, are pretty stark black and white
with no shades of grey. To make a continuous tone image print on a
copy machine you have to break the image down into a pattern of black
and white (like little dots and big dots) that gives the illusion of tone.
There are several filters that can accomplish this in Photoshop. Just
keep the principal of black dots, or any discrete black shapes of
varying size (the shape really doesn't matter) in mind and you'll come
up with interesting images.
Hope that helps,
Bob Dawson
