I’m experimenting with making my own stamps from Toyobo photopolymer letterpress plates. I had a try the other week with a different make, which didn’t turn out as well as I’d hoped, but this material is much better, much crisper with more detail. I tried out three exposure and three curing times and then printed them up with Intaglio Printmaker’s Etching Ink Shop Mix Drypoint Black. I printed them onto a page from my sketchbook and made notes.
I used a photograph of Sparta Puss as my source material, put it through the Threshold function in Adobe Photoshop and did an Invert to make a negative (I also tried out a positive as well) and printed out onto acetate to get a transparency.
