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.
