I didn't - this was done outside. One simply sends them plotter files
etc and they do it all from that.
My one offs are breadboards. The sH was a sight to behold, but worked
incredibly well.
I know Stuart Honeyball produced some commercial boards but printing
direct onto special film.
How? He didn't have a laser printer at the time and I did them for him

It apparently worked very well, but there is loss of quality. No chance
of .5mm romdisq type pitches by this method.
