So I took my leather punch (looks kind of like an ice pick) and scratched a bunch of lines onto the block that already had the circles carved into it. Nothing planned out, just went straight at the wood with the point of the tool, trying to make marks like a stray electron would make. It was difficult because the grain of the wood wanted to pull the tool in one direction only. I made the marks lightly at first so the grain wouldn't fight me so hard and then went back over them more deeply once I had scored the wood. Then I put down some blue pigment like I did the first time, using the maru bake to drive the ink down into the scratched lines. I lightly wiped some of the ink off the block and here's what printed:
You can see that the incised lines didn't fill with ink and print darker the way I thought they would. Instead, they printed as thin white lines with darker ink around them. Here's a closeup:
I put down a layer of yellow then, to see if the lines would stay white or change:
The lines pretty much stayed white, but got even darker around the edges. I wouldn't call this intaglio, but these lines are taking the ink differently and that's what I wanted. I have a few more passes to make, so it will be interesting to see what happens. I know that the wetter the wood gets with subsequent printings, the more the lines will close up. But even if these lines stay white, I feel like I've discovered a different type of mark to add to my repertoire.
