Once one has the liquid forms of the Pt/Pd chemistry, what's a good way to portion it into the quantities needed for coating and printing? At the workshop I attended, we used drops. I don't think "drops" lends itself well either to consistency or to decent discrimination. For example, there's a huge difference between two and three drops of Pt. I suppose one way would be to decrease the Pt concentation and use more drops. But, it seems to me that drops themselves are a problem. What if one loses their eye-dropper? Years of testing and experience goes out the window. There must be a better way that's reasonably priced.
