Though originally I had planned to silk screen the acid resist for the angels, I think that in the long run reverting to the PnP Blue method of toner transfer that I’m already familiar will work out better. Like many users of PnP, I have been frustrated by the consistency of transfer. Sometimes I could get a really clean transfer and other times — total failure. The image below shows both.
Also, most of the tutorials that I have read focus on PCB etching. While the principles are the same there are many tricks that I have found to adapt the basic techniques to larger scale, art etchings on brass.
I’m taking notes and better quality photos. When I can catch my breath I’ll be writing a detailed tutorial for this method of resist toner transfer for artists.
