I've been nosing around in a printmaking class at Harvard, exploring some other techniques for printing using unconventional techniques and materials. Since we've got a lot of toys to play with at the Media Lab, last week I finally got round to running some experiments with the laser cutter and hard-ground that I've been meaning to get to.
I've been nosing around in a printmaking class at Harvard, exploring some techniques for printing using unconventional processes and materials. Since we've got a lot of toys to play with at the Media Lab, last week I finally got round to running some experiments with the laser cutter and hard-ground that I've been meaning to get to.
I used some simple processing code to generate the shapes (at least, the circles and the spiral), and burned the resulting designs into the zinc plates, before etching them normally. I was skeptical, initially, because it appeared that the laser had not cut down to the bare metal, and even a thin layer of ground would prevent the acid from doing its work. That didn't appear to be a problem, though.
Working with the laser cutter generated some nice qualities in the plate. The uneven nature of the hard ground meant that the laser melted through it somewhat irregularly. It also appeared that the hard ground didn't ablate away cleanly, but rather, melted in place. It'd be worth experimenting with some other grounds.
