Abstract: This paper analyzed two cases， which applied for re-identifications on whether the wordings of the printed documents were printed at one time. It was indicated that in such cases， the main features of printed documents， such as paper， ink color， distribution， etc， were the foundation of identification. In addition， non-specific features like horizontal line sloping， line spacing， margins， font characteristics， etc， need to be utilized carefully， because they could be changed through manual settings. A comprehensive analysis of these features will lead to an objective conclusion in the identification of printed documents. 

Key words:  , printing document, re-identification
