I have 3 `copies` of a document.
1 is original (ball point) and 2 are copies (laser printer)
They all look similar, so does anyone know of a way to differentiate the
`wet signature` from the copies.
I have tried a UV light but doesnt show a difference.
Without causing any destruction as they are legal documents.

The original ball point will have indented the paper, and possibly
any sheets underneath it. This may be more visible from the rear.

Also, the colours on the copies are unlikely to exactly match the
original, although the copies may well match each other.
