1. A polymerizable printing ink, comprising:

  • a polar suspending medium;

    a plurality of monodisperse polymer microspheres suspended in the suspending medium;

    a coloring agent chemically associated with the microspheres;

    a surfactant dispersed in the suspending medium to stabilize the microsphere suspension; and

    a monomer, including at least one unsaturated group, positioned in the ink such that polymerization of the monomer after applying the ink to a substrate secures the microspheres in a fixed relation to one another.
