We were discussing the photo etch process, not toner transfer. NaOH solution
is for developing the resist after UV exposure.
Everyone uses different software. I use Pulsonix which is excellent but
rather expensive. A free version of Eagle is available that will do small
boards, but it isn't an easy program to use. Then there is PCB (completely
free) which is usually run under Linux. KiCAD is another free program.
