What is the function of an embosser?

An embosser is primarily used to create raised marks on paper documents. This process produces a tactile effect that can be felt when the document is touched, which adds a level of security and authenticity to important papers, such as notarized documents. The raised impression often serves as a seal of authority and can help verify that a document is legitimate, thereby preventing forgery or tampering. While other options present functions related to document handling, they do not correctly describe the specific and unique role of an embosser.
