Reproducing this color print shop demo on youtube:

It's interesting how the bitmap colors differ from the output pdf where the pdf looks more authentic.

I also got the file size a bit smaller (like 10x smaller) by not setting the color for every output dot and by using strokes instead of fills to make the dots.
