The purpose and use of professional engineer seals: Upon issuance of a professional license, each holder is required by most states to obtain a seal meeting the state requirements. The purpose of the engineer seal or stamp is to assure the user of the product that the work has been performed or directly supervised by the professional named and to delineate the scope of the professional’s work.
Pre-inked stamps are made of a porous stamp die and the ink is infused into the stamp die. These professional stamps do not require a stamp pad and are compact and have fewer moving parts than the self inking stamp. The pre-inked stamp will last for thousands of impressions and can be re-inked if needed.
The ink colors available are black, red, blue, green and violet. The stamps are not suited for use on non porous surfaces.
