Some of the prints that I made along with the used plates.
I etched away the non-printed material out of chipboard.
I tried cutting, but ran into technical issues (see unused plate at lower left). I would like to return to this method, because it’s faster and much less messy. I just need to work out some of the logistical details.
Actually, except that you are removing the nonprinting surface instead of adding the printing surfaces, this looks like a colograph as much as a block print, because of the materials. I think in colography, people usually paint a layer of shellac on the cardboard, to help the cardboard survive the ink application. Might be a fun experiment.
@julschauer I’ve cut bookboard, which could be like your chipboard, with speed 150 power 100. Might be a good starting point.
