I’ve added another color, burnt sienna, to the two surviving test prints (there were three, but I made the boneheaded move of printing one upside down, of course) . Also the test on top has a bit of a turquoise bokashi that deserves its own block on the sky and water. I might have registration problems with the green; that is too be seen.
Next, I printed the key block lines in a light sumi on test #2.
Many of these lines are way too heavy, but this will let me see which I can trim down, which I can eliminate completely, and where I truly have registration issues. Progress!
