Abstract
A method for creating color images is provided. This method includes providing at least one color precursor, wherein the color precursor is contained within microcapsules of predetermined sizes or variable sizes; providing a substrate, wherein the substrate is coated with at least one-color-triggering developer; depositing the microcapsules on the surface of the substrate; and creating an image on the substrate by applying pressure to the microcapsules in a controlled manner, wherein the pressure is sufficient to rupture the microcapsules, wherein rupturing the microcapsules releases the color precursor for reacting with the color-triggering developer, and wherein the reaction of the color precursor with the color-triggering developer creates color on the surface of the substrate.
