摘要： Method of operating an inkjet printhead for printing on a substrate; the printhead having a chamber communicating with a nozzle for ejection of ink droplets and with a supply of ink; the printhead further comprising electrically actuable means associated with the chamber and actuable a plurality of times in accordance with print tone data, thereby to eject a corresponding number of droplets to form a printed dot of appropriate tone on the substrate; the method comprising the steps of applying a plurality of electrical signals to the electrically actuable means in accordance with the print tone data, the time delay between application of successive signals being such that any variation in the average velocity at which corresponding droplets travel to the substrate to form said printed dot remains below that which would lead to defects in the printed image detectable by the naked eye, regardless of the number of said droplets ejected to form said printed dot.

摘要： A thermal ink jet printer including a printhead (17) having a plurality of ink drop firing resistors (26, R1-R8) responsive to ink drop firing pulse groups wherein a pulse group includes one or more pulses sufficiently closely spaced to produce respective droplets which merge in flight to form an ink drop whose volume depends on the number of pulses in the pulse group. The pulses in a pulse group are controlled such that the energy of the second and successive pulses is less than the energy of the first pulse. The intervals between leading edges of the pulses in a pulse group can be constant or reduced such that the intervals between adjacent pulses beginning with the second pulse is less than the interval between the leading edges of the first and second pulses.

摘要： An ink jet drop-on-demand printing system comprising an ink jet print head (10) having an ink cavity (23) supplied with a suitable ink. An electromechanical transducer (16) is mounted in mechanical communication with the ink cavity, and a control means (14) is provided to selectively actuate the transducer to produce an ink drop of a selected size. To produce ink drops of a selected size a source of electrical signals comprised in the control means produces electrical drive signals (60a to 60n) each separated by a fixed time delay (τ) which is short with respect to the drop-on-demand drop production rate (T). Each electrical drive signal (60a to 60n) is capable of ejecting a predetermined volume of ink and all ejected the volumes of ink merge to form a single drop prior to the time the ink drops reach the print medium for printing. By selecting groups (e.g. 60a to 60d, or 60a to 60f) from the signals (60a to 60n) the size of the merged drop can be selected.

摘要： A liquid discharging method is disclosed for a liquid discharge head which includes a discharge port constituting the portion for discharging liquid, an energy generating element generating the energy for discharging liquid, and liquid flow paths communicating with the discharge port and equipped with the energy generating element, which forms a plurality of droplets by discharging the liquid from the discharge port by the energy of the energy generating element, and which performs recording by shooting the plurality of droplets onto a recording medium. Herein, the plurality of dots is formed of a main droplet which flies at the start; and a droplet formed by coalescing, after capturing, a plurality of satellite droplets which is discharged as a result of the discharge action of the main droplet, before the satellite droplets have been shot onto the recording medium.

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.
