I am THRILLED that you brought up printmaking applications. I have a fine arts printmaking background, and the printmaking applications with a laser are pretty much endless. I’ve done laser-aided linoleum block printing on canvas:
And on the wall at work right now are these experiments in laser-aided screenprinting:
I haven’t done specifically letterpress-related applications yet, but it’s high on my list. I think Dan also has a good thought about multi-plate applications-- usually with letterpress that has an illustrative effect, but you could achieve the look of a full-color photo with laser-engraved lino blocks. I’ve also engraved type as small as 4pt on lasers, though printing that small might be iffy.
I’m interested in accessibility-- like, how do we make etchings without needing chemicals or letterpress wood without having to know how to cure and plane it? Having a good source for materials helps, but finding that source can be a huge amount of work.
Are you imagining making band posters? Fine art? Gag gifts?
