摘要:
A droplet forming device (100) is provided. The droplet forming device (100) includes a liquid holder (11) configured to hold a liquid (15), a film (12) having a discharge hole (14), two or more vibration generators (13A; 13B) configured to vibrate the film (12), and a driver (20) configured to apply a driving signal to the vibration generators (13A; 13B). One or more of the vibration generators (13A; 13B) are disposed in each region on the film (12) where a polarity of bending moment differs.

Under a condition in which bowed printing occurs, a horizontal shift is suppressed to improve print quality. Following a program stored in a ROM 12, an MPU 10 generates video data for charging print particles according to print contents data stored in a RAM 11 . Based on the print contents data, the MPU 10 detects a letter to be printed last, and when the letter to be printed last is printed to end a print operation, generates video data so that based on the video data, a non-print charge voltage driving non-print particles to an extent that they do not fly over a gutter 25 is applied to non-print particles. The number of the non-print particles subjected to the non-print charge voltage is determined by the MPU 10, based on the distance from a print head 2 to a print subject 30, a letter height preset value, etc. A character signal generating circuit 18 generates the non-print charge voltage, based on the video data, and applies the generated the non-print charge voltage to a charging electrode 22.

Provided is an inkjet recording device for performing print control by increasing or decreasing the number of adjustment ink particles, which are used according to the speed of the object being printed even when the movement speed of the object being printed is increasing or decreasing and which are uncharged particles carrying a fixed electrical charge that takes electrostatic bonding into consideration. The present invention is an inkjet recording device provided with an ink container for holding ink that is to be printed on the object being printed, a nozzle that is connected to the ink container and discharges the ink, a charging electrode for charging specified ink that has been discharged from the nozzle, a deflecting electrode for deflecting the ink charged by said charging electrode, a gutter for collecting the ink that is not used for printing, and a control unit for controlling the printing. The inkjet recording device is characterized in that the control unit performs control so that ink particles which are not used for printing and are adjacent to ink particles that are used for printing are charged by the charging electrode.
摘要:
Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur Erzeugung, insbesondere auch zur Ablenkung von Tintentropfen unterschiedlicher Größe insbesondere innerhalb eines Schriftbildes eines kontinuierlich arbeitenden Tintenstrahldruckers, wobei aus einer Düse einer Druckkammer ein kontinuierlicher zusammenhängender Tintenstrahl austritt, bei denen eine Folge von Schallpulsen (140, 142) seitlich zur Ausbreitungsrichtung (100) auf den zusammenhängenden Tintenstrahl (9) trifft, und mit jedem Schallpuls (140, 142) ein Abschnitt (12) des Tintenstrahls (9), auf den der Schallpuls einwirkt, aus dem zusammenhängenden Tintenstrahl (9) herausgelöst und aus seiner ursprünglichen Ausbreitungsrichtung (100) abgelenkt wird, wodurch der ursprüngliche Tintenstrahl (9) unterbrochen wird und in der ursprünglichen Ausbreitungsrichtung (100) einen Tintenstrahl aus den verbleibenden Abschnitten (Sa, Sb) ausbildet, deren jeweilige Länge durch den zeitlichen Abstand zwischen zwei auf einander folgenden Schallpulsen (140, 142) wählbar ist.
摘要:
A liquid discharge apparatus having heads (11) with liquid dischargers including nozzles (18) aligned in parallel in a row. The apparatus comprises: a discharge-direction changing unit for changing the trajectory of droplet discharged from the nozzle of each liquid discharger in at least two different directions in the row; and a discharge-angle setting unit for selecting discharge angles for each droplet discharged from liquid dischargers controlled by the discharge-direction changing unit for each liquid discharger.
摘要:
A method and apparatus for printing a desired pattern on a substrate (4) by discharging continuous stream of liquid ink drops (5) from nozzles (2) towards the substrate (4), and selectively charging the liquid ink drops (5) with multi-level charges deflecting them different amounts. Some of the liquid ink drops (5) are thus directed to different locations on the substrate (4) for printing the desired pattern thereon, while other liquid ink drops (5) not to be printed are intercepted by a gutter (8) before reaching the substrate (4). At least some of the liquid ink drops (5) to be printed being either uncharged or charged with a multi-level charge of one polarity, while all the liquid ink drops (5) not to be printed are charged with a charge of the opposite polarity. Each stream of ink drops (5) discharged from a nozzle (2) is illuminated with stroboscopic light (10) at the same frequency as the drop formation, and the illuminated stream is optically sensed on the fly from determining various conditions, including ink velocity, X-axis offset and Y-axis offset.
