I had moderate success with the following:
Scan it, very well, as line art ad carefully set the treshold.
(Alternatively you may scan as image and convert to 2-color in your
software.)
Now, increase color depth again in your software, and blur the image. This
takes out many of the scanning artefacts ("stubble"), if you convert to
2-color again and set the threshold, once more, very carefully. I would
expect there's software specifically for removing "stubble" (the 1-pixel
wide uncertanity around the contour).
This does work, but not too well, and a hamster can't be trained to do it.
Batch processing might be set up but without user intervention i think it
unlikely to work.
I have been paid in the past to convert pictures to a layout format
(gerber output in the end), so there is no quick and easy way. What i
usually do is import the "picture" as a unused layer for a ackground in my
software.
