This is PCB ... I really only see about 8 greys needed at most.
I still would stick to any lossless format however.
It may very
well be case that a 600dpi scan using lossless
compression will be much cleaner and usable than a 3200dpi scan using
heavy JPEG compression.
I question the "much". JPEG uses 8x8 blocks, so a 3200dpi JPEG cannot
lose more information than a 400dpi lossless, and I'm not convinced a
3:2 difference is enough to earn that "much".
