    • A microfluidic printing apparatus for transferring ink to a receiver includes at least one ink reservoir; a structure defining a plurality of chambers arranged so that the chambers form an array with each chamber being arranged to form an ink pixel; a plurality of microchannels connecting the reservoir to a chamber; and a plurality of microfluidic pumps each being associated with a single microchannel for supplying ink from an ink reservoir through a microchannel for delivery to a particular chamber. Air is delivered to isolate ink in the chamber so that a predetermined amount of ink in the chamber can be transferred to a receiver, and the microfluidic pumps are operated for delivering the predetermined amount of ink to each chamber.

    • A method for microfluidic printing continuous tone color pixels on a reflective receiver by using cyan, magenta, and yellow inks, including supplying a fourth, colorless ink along with the cyan, magenta, and yellow inks needed for color printing and pumping the inks through capillary microchannels by microfluidic pumps. The method further includes mixing the correct amount of colorless ink with the cyan, magenta, or yellow inks to produce mixtures of ink having a desired correct hue and tone scale; and transferring the pixels of the ink mixtures to the reflective receiver to form colored pixels on the receiver comprising a support, a layer formed over the support of an ink impermeable material and cavities defined in a surface of the ink impermeable layer and an ink absorbing material disposed in the cavities for absorbing a determinable amount of ink until saturated such that ink is not conveyed to adjacent cavities.
