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?

Put the print on the scanner and place a piece of black paper/ card over
the top of it and see how it comes out. Something like photoshop can
improve the contrast of the scan.
