  • Four color digital printing process and color image element using color-sensitive photopolymers
    Publication number: 20040045465
    Abstract: A process of forming a color image element with color-forming photopolymer layer(s), the color image element so formed, and a digital imaging system is provided. A single subtractive working color-sensitive, photopolymerizable layer on a substrate which, upon exposure to an actinic radiation source reflected from a digital light processor accurately reproduces a desired digital color image in the photopolymerizable layer. The use of multiple layers of color specific photopolymers enable a full color image to be formed upon the substrate by this process.
