ABSTRACT:
A microfluidic printing apparatus for printing ink pixels on a receiver including at least one ink reservoir; a moveable plate having a plurality of delivery chambers in an array each for forming an ink pixel, and a plurality of microchannels connecting the reservoir to a delivery chamber; and a plurality of microfluidic pumps each being associated with a single microchannel for supplying ink to particular delivery chambers. The receiver is sequentially moved under the delivery chambers and moving the moveable plate between different positions for permitting the delivery chambers to sequentially deliver ink from its associated microchannel into its associated delivery chamber where it is transferred to the receiver to control the amount of ink delivered to form pixels on the receiver at a plurality of locations; and a computer for controlling the microfluidic pumps and the movement of the moveable shutter plate for causing the correct amount of ink to be conveyed into each delivery chamber for transfer to the receiver to form a colored pixel.
