impression of a seal; seal imprint
Refers to the stamped image or mark left by a seal (hanko/inkan), as opposed to the physical seal itself.
The seal impression on the contract has become faint.
To leave a clear seal imprint, please apply the ink pad firmly.
Compound of 印 (seal, stamp) and 影 (shadow, image), literally 'seal shadow'. The exact historical derivation is uncertain, but the word transparently describes the visual impression left by a seal.
