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?
