Seetrax Ranger has a tough learning curve.
Some programs are available as freeware while others cost a fortune.
I use Seetrax Ranger. The final PCB layout and solder mask legends are scaled-up and printed on a laser printer. I then copy the PCB layout on a document film such as AgfaOrtho or similar. These films have extremely high contrast when developed right. After processing the film I now make a positive copy onto a graphical film as Kodak ELF or other special-purpose film.
