There is a great study by Nasa of label and checklist font readability. It recommends a good font which I used. Google finds it easily.

Problem with engraved or "plasticied" labels is that there are a lot of fuses and switches in panel that requires very small labels. These can be done only with printable sheets. This way you get exactly same look and feel of factory new glider.
