摘要： A drive circuit (100) for driving actuators of a printhead (97) from a common drive waveform has a switching circuit (32) for coupling the common drive waveform to an actuator (1,2), and a timing circuit (10) to control the switching circuit to form a drive pulse from the common drive waveform. The drive pulse is trimmed by controlling a duration (TTRIM) of a step at an intermediate level (VHOLD) in the drive pulse. This can improve the trade-off between available range of trimming and thermal efficiency because the voltage drop across the switching circuit can be reduced, compared to trimming only the height. Decoupling during a flat portion of the common drive waveform can enable the timing of the decoupling to be more relaxed compared to decoupling during a slope. Such relaxing can enable costs, complexity and thermal loading to be reduced.

摘要： A method for depositing droplets onto a medium, utilising a droplet deposition head is provided. The head used in the method includes: an array of fluid chambers separated by interspersed walls, each fluid chamber communicating with an aperture for the release of fluid droplets and each wall separating two neighbouring chambers. Each wall 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, and, in response to a second voltage, it will deform so as to cause the opposite effect on the volumes of its neighbouring chambers. The method includes the steps of: receiving input data; assigning, based on such input data, all the chambers within the array as either firing chambers or non-firing chambers, so as to produce bands of one or more contiguous firing chambers separated by bands of one or more contiguous non-firing chambers; actuating the walls of certain of the chambers such that: for each non-firing chamber, either one wall is stationary while the other is moved, or the walls move with the same sense, or they remain stationary; and, for each firing chamber the walls move with opposing senses; such actuations result in each firing chamber releasing at least one droplet, the resulting droplets forming bodies of fluid disposed on a line on the medium, such bodies of fluid being separated on the line by respective gaps for each of the bands of non-firing chambers, the size of each such gap generally corresponding in size to the respective band of non-firing chambers. The actuations of the walls of said firing chambers in the actuating step are such that, if only one of the two walls of each firing chamber were actuated in such manner, no droplets would be ejected from that firing chamber. A droplet deposition apparatus, a droplet deposition head and a computer program product are also provided.

摘要： A droplet deposition apparatus, such as an inkjet printhead, that includes an integrally-formed manifold component and one or more actuator components; these actuator components provide an first array of fluid chambers, each of which has a piezoelectric actuator element and a nozzle, with this piezoelectric actuator element being able to cause the release in a deposition direction of fluid droplets through the nozzle in response to electrical signals; the first array of fluid chambers extends in an array direction from a first longitudinal end to a second, opposite longitudinal end, this array direction being perpendicular to the deposition direction; in addition, the manifold component is elongate in the array direction and includes a first and second manifold chambers, with these manifold chambers extending side-by-side in the array direction and the first manifold chamber being fluidically connected to the second manifold chamber via each of the fluid chambers in the first array; the cross-sectional area of at least one of these manifold chambers is tapered with distance in the array direction, for example to improve purging of the chambers during start-up; the cross-sectional shape of the integrally-formed manifold component perpendicular to the array direction varies with distance in the array direction such that the centroid of the cross-section remains a substantially constant distance, in said deposition direction, from said array of fluid chambers over the length of the first array of fluid chambers, with the integrally-formed manifold component thus being essentially self-stiffening.

摘要： A method for depositing droplets onto a substrate employs an apparatus, such as an inkjet printhead, the apparatus having: an array of channels, acting as fluid chambers, separated by interspersed walls, with each channel communicating with an aperture or nozzle for the release of droplets of a fluid contained within the channel, such as ink. Each of the walls separates two neighboring channels and is actuable such that, in response to a first voltage, it will deform so as to decrease the volume of one channel and increase the volume of the other channel, and, in response to a second voltage, it will deform so as to cause the opposite effect on the volumes of the neighboring channels. The method includes the steps of: receiving input data, such as an array of image data pixels; selecting pairs of adjacent channels based on the input data; assigning the selected pairs of adjacent channels as firing channels and the remaining channels as non-firing channels. While the pairs of firing channels may generally have any spacing, one of the pairs of firing channels is spaced apart from another of the pairs of firing channels by an odd number of non-firing channels. Within each of these selected pairs, the separating wall of that pair is actuated so as to cause the release of at least one droplet from each of said firing channels. The actuations for all the pairs overlap in time so as to ensure a high level of throughput or printing speed.

摘要： An ink jet or other printer serves to print for each row of input pixels, two superimposed rows of contiguous “super pixels,” each print pixel being capable of receiving print contributions from N super pixels. The super pixels are twice the width of the input pixels and one row of super pixels is offset by half a super pixel width from the next row of super pixels. Redundancy is thus provided against the loss of a print element. The effects of smoothing or an image are reduced by edge enhancement processes.

摘要： In an ink jet printhead have an elongate ink chamber and a nozzle at one end, a continuous flow of ink is provided through a high impedance channel communicating with the chamber close to the nozzle. Ink is ejected through the nozzle by generating longitudinal acoustic waves in the fluid chamber. A high velocity ink flow into the chamber from the channel sweeps away from the nozzle debris or bubbles that might otherwise block the nozzle.

摘要： Plastic or other electronic devices are formed on a flexible substrate using inkjet printing techniques. To avoid registration difficulties arising from distortion of the substrate, deposition is conducted on a rigid substrate to which a release layer is applied. After application of a type layer which serves as the permanent, flexible substrate, the structure is released from the temporary rigid substrate.

摘要： An actuator taking the form of a piezoelectric wall separating two chambers, which utilizes two actuation modes. Both actuation modes cause volume displacements in both chambers, but act to reinforce one another in one chamber and cancel one another in the other chamber. A fluid pump for droplet deposition having an array of channels separated by such actuators can be operated with each channel acting substantially independently of its neighbors.
