ABSTRACT:
A method for microfluidic display and printing includes the steps of: providing colored inks needed for printing colored pixels; pumping the colored inks through capillary microchannels into delivery chambers where the colored inks are mixed to provide a desired color for each pixel, having the correct hue and tone scale; arranging the delivery chambers so as to provide a viewable representation of the image prior to printing; and evacuating the delivery chambers when it is not desired to print an image and moving a receiver into engagement with the delivery chambers when it is desired to print an image for transferring colored ink to a reflective receiver to thereby form an image having colored pixels.
