'die Unterschrift' and 'die Unterzeichnung' are closely related, but they do not mean the same thing. 'die Unterschrift' is the written name on a document. 'die Unterzeichnung' is the process or formal act of signing a document. The words can be especially easy to confuse when talking about contracts. If you mean the mark itself, you say 'Unterschrift'. If you mean the official moment or process, you say 'Unterzeichnung'.
