No surprises there, transferred toner is actually a poor resist in
comparison to resist that was developed properly. And when you
say "looked ok", what magnification are you referring to?
I did that 6/6 rules torture test to debunk a collimation myth. The
only reason why it wasn't 5/5 was because the artwork didn't make the
grade. I can do less tortuous 5/5 or 4/4 rules (to the limit of the
printer) to debunk the etching myth as well. How about .003" or .002"
lines with .005" or .004" spacing? What will it take to convince you
that etching should be the least of your worries provided you know what
you're doing? Do I have to walk on water?
