Now that I've decided which pattern to use, I've made a good plate (I hope). I've not used these open etch plates before. Instead of washing out with water, they wash out with alcohol. They are more expensive (about twice as much), and are supposed to give more impressions before they wear out (like I care).
Compare it to the one above using a screen. The image area looks like it is sticking out, but it is really an etch, or indentation.
Best wishes,
Bob
