Abstract: A method of dynamically controlling a perceived ink color printed on a substrate can include mixing selected amounts of each of a polystyrene nano-sphere dopant component and a nano-particle dopant component with a clear fluid carrier component, the mixed components configured in real time to define an ink structure having a predetermined wavelength. The method can further include imaging the substrate by ejecting the mixed components onto the substrate, the perceived color of the imaged substrate corresponding to a reflected wavelength of the ink structure. In embodiments, each of the carrier and dopant components can be in a powder form suitable for fuser type imaging devices.

Abstract: An imaging system including a substrate; a monoclonal antibody coated on at least a portion of the substrate; at least one antigen dye that will bind to the monoclonal antibody coated portion of the receiving substrate upon exposure to light; wherein an image projected onto the monoclonal antibody coated substrate is recorded in the antigen dye particles that bind to the monoclonal antibody coated portion of the substrate.

Abstract: A hierarchical architecture for a network printing system having a plurality of electronic printers and printing systems is provided. The hierarchical architecture decomposes each electronic printer and printing system's Digital Front End (DFE) and print engine into a hierarchical set of networked printer components communicating via a many-to-many network protocol. Print data is routed from component-to-component based on the receiving component's self-advertised function and availability. Adding duplicate printer components to the network environment scales or increases the reliability and performance of the network environment. A sufficiently large set of inexpensive printer components may be configured to achieve any desired level of reliability and performance through redundancy.
