Patent ID: 8567923

Claim:
Method for depositing droplets onto a substrate, utilizing an apparatus comprising: an array of fluid chambers separated by interspersed walls, each fluid chamber communicating with an aperture for the release of droplets of fluid and each of said walls separating two neighboring chambers; wherein each of said walls is actuable such that, in response to a first voltage, it will deform so as to decrease the volume of one chamber and increase the volume of the other chamber, in response to a second voltage, it will deform so as to cause the opposite effect on the volumes of said neighboring chambers; the method comprising the steps of: receiving input data corresponding to an image; applying an algorithm to said input data, the algorithm converting said input data, regardless of the image, to a representation of the input data made up solely of pairs of print pixels; selecting pairs of adjacent fluid chambers based on said representation of the input data; assigning said selected pairs of adjacent fluid chambers as firing chambers and the remaining fluid chambers as non-firing chambers, wherein one of said pairs of firing chambers is spaced apart from another of said pairs of firing chambers by an odd number of non-firing chambers; and for each of said selected pairs, actuating the separating wall of said pair of firing chambers so as to cause the release of at least one droplet from each of said firing chambers; wherein said actuations of said selected pairs overlap in time.
