Abstract
Depositing droplets onto a substrate using an array of channels, acting as fluid chambers, separated by actuable walls. In response to a first voltage, each wall deforms to decrease the volume of one channel and increase the volume of the other channel, and, in response to a second voltage, the wall deforms so as to cause the opposite effect on the volumes of the neighboring channels. Receiving input data; assigning, based on the input data, all channels within the array as firing or non-firing to produce groups of one or more contiguous firing channels separated by groups of one or more contiguous non-firing channels; actuating walls of certain channels resulting in each of the firing channels releasing at least one droplet of fluid, the resulting droplets forming dots disposed on a straight line on a substrate, separated on the line by gaps corresponding to the non-firing channels.
