This looks interesting and promising. I haven’t done any silk screening in a while, but I think I would give it a try again if I could create screens as easily as this. It kind of dovetails with those halftone tests @kittski did nicely as well.
Just realized i should credit where I found this. I thought it had come from a generic laser cutting facebook page, but it was actually someone on the glowforge user group page. Not sure if they’re here, but Kevin, if you are, thanks for posting this there.
