Hello everybody, just a theoretical question.
When you apply a toner to a copper board, and you start etching it with your acids, why does it not dissolve all the copper ? As in, the toner is applied, it keeps the acid from dissolving through the toner, but would it not at some point start going UNDER the toner ? Ilustartions in mspaint
