Subject: Re: Help with etching - accuracy

Interesting idea.

but what is the overall accuracy ?

it would seem that a PCB could be off more than just a few thou over
the lenght of a 10 inch board and still be very accuracte for
locating chips and stuff.

Has anyone done realworld tests ?

I would assume that inkjet and laser and copiers would not be perfect
as the US treasury has dictated that such machine cannot be exact 1:1
ratios. goes to preventing the average Joe from making their own $$$$
