It's hardly a masterpiece, but it did demonstrate some of what I needed to know about these new materials:
- They go on to the metal very well, and they seem to be highly acid-resistant.
- They don't like a very highly-polished plate, but they adhered fine to this one which I polished with 0000 steel wool. I guess that will mean that if I don't want any plate tone in my prints, the plate might need a bit of localized polishing after etching is complete.
- They cure pretty quickly, as acrylics tend to do.
- It's not a good idea to try to accelerate drying with heat, as the differential in thermal expansion/contraction between the resist and the copper can dislodge small areas.
- You'll need to be washing out your brush very regularly or the resist will cake in it.
- It washes off the plate very easily with methylated spirits — Lascaux do offer a "remover", but meths is cheap and easily accessible. I haven't tried washing it off after being left on the plate for any extended length of time though.
Next I shall have to try drawing into the hard ground with an etching needle for an intaglio line. That will be the real test.
