Which feature is a requirement for the imprint of an official seal?

The imprint of an official seal must be capable of being photocopied to ensure the seal is clearly identifiable on documents for which it is used. This feature is crucial because it allows for the seal's validation and authenticity to be reproducible in copies of the document. A seal that cannot be photocopied might lose its significance when documents are duplicated, possibly leading to questions about the validity of notarized signatures or transactions.

Other options, such as the color of ink or the shape of the seal, may vary based on individual preferences or requirements, but the primary function of the seal—assuring that it can be effectively reproduced—takes precedence in maintaining the integrity and acceptability of notarized documents. Hence, the capability of being photocopied is an essential characteristic for the official seal.
