A more thorough explanation:

An embossed seal is a type of notary seal that is impressed onto a document, raising the impression above the surface. This type of seal clearly identifies the original document because the seal is only faintly reproducible. It is required in some states and on some documents notarized for federal purposes.

For example, when a notary public notarizes a legal document, they may use an embossed seal to make an imprint on the paper. This imprint is raised and cannot be easily reproduced, making it a secure way to verify the authenticity of the document.

Another type of notary seal is a rubber-stamp seal, which is ink-stamped onto documents and is therefore photographically reproducible. This type of seal typically includes the notary's name, the state seal, the words “Notary Public,” the name of the county where the notary's bond is filed, and the expiration date of the notary's commission.

Overall, an embossed seal is a secure and reliable way to verify the authenticity of a notarized document, making it an important tool for notaries public.
