See http://www.paulroark.com/BW-Info/Draw-Down-Procedure.pdf for a brief explanation of the "draw-down" procedure. It's just a quick way to quality control ink batches and also take a first look at a potentially interesting ink.

Paul, if you can find the time, do you think you could explain what this "draw down" test is all about? I suspect the vast majority of subscribers to this list are more than a few steps behind you in your understanding of the technology of printer inks. A little more explanation would likely help a lot of us to move a step or two in your direction. Thanks for this and all your work.
