up a rig where I pump fuel into the injectors, and perhaps use a piece of
cardboard 12 inches from the injectors to see what the spray pattern looks
like after a shot of fuel. I would be looking for uniformity of pattern from
all injectors.
Am I missing something else I should look for?

Please excuse me if this does not apply.
I don't know about gas injectors, however I have experience with Diesel Injectors which I believe work on the same principle.
You have to have a break pressure, the injector holds the fuel until a certain fuel pressure
is built up,You will have to find out what the pressure would be, then it is injected, You check the spray patern, like you said. The injector cannot "dribble" it has to hold the pressure till it is injected.
Do a Google on Diesel Injectors, it will give You ideas
