Yes, it can be done. Below are a couple of small prints I made as a proof of concept. I covered the relief surface not with ink but with a dark graphite pencil! Put some dampened paper over top and run through the press and you end up with this; nicely embossed images that I’m personally quite happy with. Both are a minimalistic couple inches in size and centered on an 8″ x 10″ sheet for easy framing.
This is an open-edition print. The first print, I think, is pretty self explanatory, the second one is the word LOVE spelled out using computer binary language – L on the top and E at the bottom. I based these two prints on two pendants I designed, each of which is available in my Shapeways shop.
Available in my Etsy store.
