I edited the layouts pixel by pixel and then printed them onto transparency
with a lazer printer. The graphixs were perfect and the etching turned out
perfect by the third trial. I have a really neat setup for etching. I have
the ferric chloride in a tuperware set into another tub with water and a
fish tank heater. I also have an air pump airating the solution. Works like
a charm :).
I havn't had so much fun in quite some time.
