I have a rather poor quality but full size print of a printed circuit board I wish to duplicate. It's on cheap thin paper with printing on the other side. My scanner gives the best results when using grey rather than B&W. But of course shows the print on the other side. And the edges of the tracks are pretty ragged.
Of course I could just use this as a guide and draw an entire new one - but wondered if it was possible to clean up the track edges and produce only B&W in software?
