Abstract
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; pumping the inks through capillary microchannels by microfluidic pumps; mixing the correct amount of colorless ink with the cyan, magenta, or yellow inks to produce both the correct hue and tone scale for each colored pixel; and transferring the colored pixels of mixed ink to the reflective receiver to form colored pixels on the receiver.
