Summary:REFERIDO A UNA COMPOSICION PARA FORMAR UN REVESTIMIENTO MEJORADOR DE MIGRACION PRIMARIO, QUE COMPRENDE UN ACEITE, UNA RESINA, UN AGENTE ANTI-VAPORIZACION, UN AGENTE ANT-OFFSET Y MATERIAL FLUORESCENTE. ADEMAS, SE DESCRIBE UN SISTEMA PARA PRODUCIR UN DOCUMENTO SEGURO QUE COMPRENDE: UN SUSTRATO QUE TIENE UNA PRIMERA Y SEGUNDA SUPERFICIE; UN TONER; UN REVESTIMIENTO QUE COMPRENDE MATERIAL FLUORESCENTE APLICADO A LA PRIMERA Y SEGUNDA SUPERFICIE USANDO IMPRESION OFFSET, EN DONDE EL TINGUE EXTINGUE UNA PORCION DE DICHO REVESTIMIENTO PARA PRODUCIR UNA IMAGEN NEGATIVA INVERSA DE UNA IMAGEN IMPRESA CON EL TONER, CUANDO SE EXPONE A RADIACION ULTRAVIOLETA A coating composition, system, and method for printing documents that are difficult to chemically or physically forge and that are easy to visually verify are disclosed. The system includes a substrate, a toner, including a colorant and a dye, a coating including fluorescent material, e.g., a primary migration-enhancing coating, applied using an offset printing process and optionally a secondary migration-enhancing coating applied using an offset printing process. An image formed using the toner of the invention is readily verified by comparing a colorant-formed image and a dye-formed image and/or to a reverse negative imaged formed by the dye quenching the fluorescent material. In addition, if a solvent is used in an attempt to alter the printed image on the substrate, the dye migrates or diffuses to indicate tampering with the document.
