I regularly and dependably do 10 mil tracks with 603 and 805 size components. I can do SSOP ICs but that's pushing it and generally requires a bit of hand cleanup to remove shorts between adjacent pads. It's difficult to make such closely spaced pads, I believe the toner squishes out a bit and makes them wider.
