I'm working on a Duo-Art test roll right now!
I have scanned two different original British test rolls. However, I'm thinking of making something a bit more thorough because the old rolls were designed to adjust instruments that were in good condition and had recently been shipped from the factory. These days many instruments are in poor condition and have suffered substantial work / abuse! There are more things to test than on the original test rolls.
I've got no means at the moment of printing instructions on the roll, but it ought not be too difficult if an A3 printer with banner-printing capability can be found. It's nearly as convenient to put the instructions in a separate booklet - until you lose the booklet, of course.
The commonest DA test roll around in the QRS recut of American "Test roll number 3", which has all the printing on it.
