    摘要: A composite color includes a first colored ink and a second colored ink. The first colored ink exhibits a color that is different from that exhibited by the second colored ink. The first colored ink includes pigment particles either formulated at a basic pH so that a surface of the pigment particles carries a net negative charge or formulated at an acidic pH so that a surface of the pigment particles carries a net positive charge; and the second colored ink includes pigment particles either formulated at an acidic pH so that a surface of each of the pigment particles carries a net positive charge or formulated at a basic pH so that a surface of the pigment particles carries a net negative charge. The first colored ink and the second colored ink have opposite charges. The composite color exhibits enhanced color richness when printed on a substrate.

    摘要: Rigid-rod monomers and polymers are provided for use in applications such as rapid prototyping, composites and adhesives. The monomers can be photocured through the end groups and then thermally post cured through the acetylene groups. The result is a highly crosslinked polymer having an effective glass transition temperature well above 200° C.

    摘要: A method of security printing can comprise the steps of printing a transparent ink onto a portion of a coated substrate resulting in printed region and an unprinted region, where the transparent ink is devoid of dyes, pigments, ceramics, metallics, and fluorescents; illuminating both the printed region and the unprinted region of the substrate, where the printed region scatters more light than the unprinted region creating a contrast; and detecting the contrast with a sensor that is sensitive to detecting light scattering differences between the printed region and the unprinted region.

    摘要: An ink level sensing device and associated method. The ink level sensing device includes a near infrared illumination source that emits near infrared light, and a container configured to accommodate a supply of ink containing light absorption material. The device further includes a protruding chamber adjacent to the container. The protruding chamber is configured to accommodate a portion of the supply of ink accommodated by the container. The device also includes a sensor that is configured to receive a signal based on an amount of the light that passes through the protruding chamber. The method includes emitting a light from a near infrared illumination source and directing the light toward a protruding chamber of the ink supply. The method further includes sensing an amount of the light that passes through the protruding chamber in the ink supply.
