  • Interface surface printer using invisible ink
    Publication number: 20020080396
    Abstract: A printer for receiving document data from a computer system and printing an interface onto a surface. The interface is based on the document data, which includes identity data indicative of at least one identity. The identity is, in turn, associated with a region of the interface. The interface also includes coded data. The printer includes a coded data generator configured to generate the coded data based at least partially on the identity data. A printing mechanism in the printer prints the interface onto the surface, including printing the coded data using an ink including an infrared-absorbing dye.
