Title: Innovations by Eugene Hoefs in Secure Document Printing
Introduction
Eugene Hoefs is an accomplished inventor based in Wheeling, West Virginia. He has made significant contributions to the field of secure document printing, holding two patents that focus on innovative coating compositions and systems designed to prevent forgery.
Latest Patents
Hoefs' latest patents include a coating composition, system including the coating composition, and method for secure images. This invention provides a method for printing documents that are difficult to chemically or physically forge while being easy to visually verify. The system comprises a substrate, a toner that includes a colorant and a dye, and a primary migration-enhancing coating applied using an offset printing process. Additionally, a secondary migration-enhancing coating can also be applied. The images formed using this toner can be verified by comparing the colorant-formed image with the dye-formed image. If a solvent is used to alter the printed image, the dye migrates or diffuses, indicating tampering.
Another patent by Hoefs is a coating composition that includes fluorescent material for producing secure images. Similar to his previous invention, this system also includes a substrate, a toner with a colorant and a dye, and a coating that incorporates fluorescent material. The images formed can be verified by comparing the colorant-formed image and the dye-formed image or to a reverse negative image formed by the dye quenching the fluorescent material. Again, if a solvent is used to alter the printed image, the dye migrates or diffuses to indicate tampering.
