  • Process for producing dry ink colorants that will reduce metamerism
    Patent number: 8278018
    Abstract: In accordance with the invention, there is a method of forming a toner. The method can include blending two or more colorants to form a sample toner and forming a sample color specimen including a printed image comprising the sample toner. The method can further include comparing spectral distribution curves of the sample color specimen with that of a target color specimen including a target color and repeating the disclosed steps until acquiring a desired spectral match between the sample toner and the target color.
