  • Use of fluorescent inks for document authentication
    Patent number: 9012871
    Abstract: In a method for introducing an authentication print characteristic in a visible image printed on paper, a part of the image is printed with an ink having first and second component dyes. The first component is less fast than the second component in response to an applied activator. The first component is normally masked by the second component but applying an activator stimulates a bleed of the first component beyond the area of the image part to create a predetermined unmasked area of the fluorescent component. The invention extends to paper on which the authentication print characteristic has been printed and to a method of detecting a forged image by analyzing paper to detect such an image bleed.
