Kamal,
I think you can do 8 mil., but I don't know how well it will
transfer to the copper and how well it will hold up during etching.
The best I could get reliably was .012" 12 mil wide traces. The
printing doesn't appear to be the problem as much as the transfer
and etching of such small traces.
