Abstract
A microfluidic printing apparatus including 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; 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; and a structure for controlling the starting times of the microfluidic pumps and the time of separation of the receiver from the ink chambers so that the correct amount of ink is delivered from each chamber to each pixel on the receiver.
