RE: Slate Engraving test runs
(edited)
You know that is a damned good Idea. I've been thinking of doing some screen printing as I have a dark basement to work in (emulsion and screens rack up costs quick though) but a print made from a slate engraving would work like a charm. Either a monoprint or by using several pieces of slate you could do a multicolored print.
What power laser cutter are you using?

I only have a 10W Diode laser so materials can be a bit limited, but I can still do glass also and mark good stainless steel, also anodized aluminium plates since you basically cut the coating, then I saw some people spray paint multilayers on canvas and engrave on that. It is time consuming though, that is a 30cm square image and took about 3 hours after some tweaks with initial tests at 4+ hours. I am actually looking at screenprinting as a nice option but that will come when I am willing to drop the money , for now I decided I should test straight up block printing , the engraver I think can cut me stencils on wood but if that is sucky I could try stencils on laser rubber and just roll fabric paint or whatever surface I am working with paint over I think. The screen printing I think would be a great addition to the bleached and reverse tie-dye shirt types,and with rubber I guess also you can do pad printing, but the rubber is pricey over time vs I feel a screen.
Thanks for the info. I asked because there is lots of scrap slate around here. Mines/quarries are only a 30 minute bike ride away.
With silk screening my only concerns are the emulsion costs. 4 hours is a long time for the laser but far quicker than doing it by hand. :D What's it like on copper or PCB circuit boards (mountains of scrap around you can sand down)
