How do you find imprints on a paper?

Hold a lamp or other lighting source next to the paper. Shine the light across the paper at a low angle, adjusting the angle and the distance until shadows form in the imprints. Take a picture of the paper with a digital camera to capture the shadows. Print the picture to read the imprinted writing.

Can signature be copied?

Each digital signature is unique to the signer and the document, you cannot copy and paste the signature from one document to another. If any changes are made to the document or the signature after signing is complete, then the signature and documents are invalid.
