摘要

Seals have been existed in Chinese history for over two thousand years and are still using today. There are numerous ways to create and use Chinese seals for fraudulent purposes. This paper presents an overview of the possible production ways of manufacturing seals using new technologies and tries to prove whether these production methods can eliminate the classical characteristics an examiner is looking for in the comparison of a reproduced seal impression to that of the original seal. It is proved that the conventional verification methods for Chinese seal impressions are still effective.
