That would be a extremely useful reference to use. I was planning
on making a web page dedicated to this very topic, but hadn't had
the time. Ideally some form of measurements would need to be
taken so all the different printing tests can be accurately
characterized. Some measurements that come to mind are; overall
relative light transmittance and line edge jaggedness (or maximum
deviation of ink droplets from an ideal line). I have a
microscope that can take pictures of line edge jaggedness.
The latter is responsible for the minimum PCB line widths that
can be achieved.

4 main factors effect print quality;

* brand of transparency media
* inkjet printer
* ink
* printer driver settings
