摘要： The present invention addresses the problem of making it possible to drive a head in a multi-drop mode using a driving waveform that is highly robust with respect to AL value and form high quality images. Said problem is solved by: the driving waveform having multiple driving pulses for varying the volume of the pressure chamber multiple times; the driving pulse for discharging the first droplet varying the volume of the pressure chamber and inducing two or more overlapping pressure waves inside the pressure chamber, and there being a phase shift of -0.6 AL to 0.6 AL between the pressure wave oscillation induced in the pressure chamber when the first droplet is discharged and the pressure wave oscillation induced in the pressure chamber by the action prior thereto; and the driving pulse for discharging the subsequent second droplet varying the volume of the pressure chamber and inducing two or more overlapping pressure waves in the pressure chamber, and there being, between the pressure wave oscillation induced in the pressure chamber when the second droplet is discharged and a composite oscillation of the pressure wave oscillation induced in the pressure chamber by the action prior thereto and the reverberation pressure wave oscillation remaining in the pressure chamber as a result of discharging the first droplet, a phase shift in the direction opposite to the phase shift when the first droplet is discharged.

摘要： A continuous liquid ejection system includes a liquid chamber in fluidic communication with a nozzle. The liquid chamber contains liquid under pressure sufficient to eject a liquid jet through the nozzle. A drop formation device is associated with the liquid jet and is actuatable to produce a modulation in the liquid jet that cause portions of the liquid jet to break off into a series of drop pairs traveling along a path. Each drop pair is separated in time on average by a drop pair period. Each drop pair includes a first drop and a second drop. A charging device includes a charge electrode associated with the liquid jet and a source of varying electrical potential between the charge electrode and the liquid jet. The source of varying electrical potential provides a waveform that includes a period that is equal to the drop pair period. The waveform also includes a first distinct voltage state and a second distinct voltage state. The charging device is synchronized with the drop formation device to produce a first charge state on the first drop and to produce a second charge state on the second drop. A drop velocity modulation device varies a relative velocity of a first drop and a second drop of a selected drop pair to control whether the first drop and the second drop of the selected drop pair combine with each other to form a combined drop. The combined drop has a third charge state. A deflection device causes the first drop having the first charge state to travel along a first path, causes the second drop having the second charge state to travel along a second path, and causes the combined drop having the third charge state to travel along a third path.

摘要： The present invention provides a method for optimising greyscale printing by designing the waveform pulses that are used to eject ink drops from a printhead as well as a printhead controller and a printer designed by the method. The pulse voltage, pulse width and pulse delay of each individual pulse of the waveform ejecting a single droplet from the printhead, are determined so as to achieve that ink drops created by merging different droplets have the same velocity and hit a printing substrate at about the same time.

摘要： A method of dispensing a single ligament of fluid (560) includes ejecting a first quantity of fluid (530) from an inkjet dispenser (300, 600) toward a substrate (350), and ejecting a second quantity of fluid from the inkjet dispenser (300, 600) toward the substrate (350), wherein the second quantity of fluid is ejected from the inkjet dispenser (300, 600) at a frequency sufficient that the second quantity of fluid catches the first quantity of fluid (530) thereby forming a single ligament of fluid (560) prior to contacting the substrate (350).

摘要： Liquid is discharged at a high frequency in a consecutive manner with a liquid discharge head having a movable member 11. A bubble 40 formed for discharge a first discharged droplet 66a grows large into a discharge port 4 side by the movable 11 substantially closing a common liquid chamber 6 side in a bubble forming procedure, and disappears fast at the common liquid chamber 6 side by the movable member 11 releasing the common liquid chamber 6 side of a flow path 3 in a bubble disappearance procedure, and reaches a state to remain at the discharge port 4 side of a heat-generating body 10. Under this state, since the bubble 40 disappears at the common liquid chamber 6 side, a constant liquid is refilled to reach the discharge port 4 side, and the bubble 40 does not yet completely disappear, a meniscus is disposed comparatively closer to a liquid discharge face. Under the circumstances, if discharge of a second discharged droplet 66b is arranged to start from this state, the liquid can be discharged well at a short interval in a consecutive manner.
