摘要： The liquid jetting apparatus includes a head member having a nozzle, a supporting member that that can support a medium, a scanning mechanism that can cause the head member to relatively move with respect to the medium, and a liquid jetting unit that can jet liquid from the nozzle. An area storing unit stores a relative area to which liquid can be jetted from the nozzle while the head member is caused to relatively move by the scanning mechanism. An out-of-jetting micro-vibrating-area setting unit can set out-of-jetting micro-vibrating areas before and after the relative area. A micro-vibrating unit causes liquid in the nozzle to minutely vibrate. An out-of-jetting micro-vibrating controlling unit causes the micro-vibrating unit to operate when the head member is located in the out-of-jetting micro-vibrating areas, while the head member is caused to relatively move by the scanning mechanism, based on the out-of-jetting micro-vibrating areas and head-position information.

摘要： The technique of the present invention improves the accuracy of calculating an amount of ink consumption in an ink reservoir used in a printer, which ejects ink stored in the ink reservoir and prints an image. In the printer of the present invention, a weight of a single ink droplet is measured in advance under a preset reference condition. In the course of printing an image, the printer detects an ink supply condition, which affects the weight of a single ink droplet, and counts a number of ink droplets ejected. The amount of ink consumption is determined by correcting a product of the measured weight of a single ink droplet and the counted number of ink droplets based on a difference between the detected ink supply condition and the preset reference condition. This arrangement calculates the amount of ink consumption by taking into account the ink supply condition, thereby improving the accuracy of calculation for the amount of ink consumption.

摘要： The present invention prevents deterioration of the quality in interlace printing. The printing system of the present invention uses a head that regulates the amount of ink spouting from nozzles and forms dots of different diameters. While the diameter of dots formed in one primary scan is restricted to a fixed value, the system of the present invention enables dots of different diameters to coexist at an appropriate ratio, thereby improving the printing quality. The printing system of the present invention shifts a nozzle array, in which nozzles are arranged at intervals of a predetermined dot pitch, by a predetermined amount in the secondary scanning direction and varies the dot diameter on every primary scan, while controlling the nozzles in an overlapping state. This enables the dots of different diameters to coexist in a specified area. One preferable application carries out halftone processing under the conditions for dots of a certain diameter at the position where a dot of the certain diameter is formed. This application controls the ratio of dot formation to a desired level. For example, the probability of formation of small-diametral dots is increased in a low-density area. Another preferable application divides the nozzle array on a print head into two groups of nozzles, wherein each group of nozzles forms dots of a specified size. Appropriate selection of the nozzle pitch and the quantity of secondary scanning feed enables printing in which large-diametral dots and small-diametral dots coexist according to a predetermined rule.
摘要翻译： 本发明防止隔行打印中的质量下降。 本发明的打印系统使用调节从喷嘴喷出的墨水量的头部，并形成不同直径的点。 虽然在一次主扫描中形成的点的直径被限制为固定值，但是本发明的系统使得不同直径的点以适当的比例共存，从而提高了打印质量。 本发明的打印系统使喷嘴阵列以预定点间距的间隔排列在副扫描方向上预定量，并且在每次主扫描时改变点直径，同时将喷嘴控制在 重叠状态。 这使得不同直径的点在特定区域中共存。 一个优选的应用是在形成一定直径的点的某一直径的点的条件下进行半色调处理。 该应用程序控制点形成与期望水平的比率。 例如，在低密度区域中形成小直径点的概率增加。 另一个优选的应用将打印头上的喷嘴阵列分成两组喷嘴，其中每组喷嘴形成指定大小的点。 喷嘴间距和二次扫描进给量的适当选择使得可以根据预定规则共存大直径点和小直径点的打印。

摘要： A method of driving an ink jet recording head comprising the steps of: retreating a vibrating plate to a predetermined position from a nozzle opening at such a speed as to allow a meniscus at the nozzle opening to be jetted from the nozzle opening while applying a drive voltage to a piezoelectric vibrating element; holding the vibrating plate at the position; and advancing the vibrating plate toward the nozzle opening when the meniscus has returned to a position 1/3 or more of the farthest retreat position thereof. As a result, a pressure chamber contracted to thereby apply pressure to ink when inertial stream of the ink become stable and heads toward the nozzle opening, producing an ink droplet to be jetted at a predetermined speed irrespective of the position of the meniscus.

摘要： In the bi-directional printing, a reference correction value is set for correcting printing positional deviation arising between forward and reverse main scanning passes with respect to specific reference dots. An adjustment value is determined, using at least the reference correction value, to reduce printing positional deviation arising between forward and reverse main scanning passes. The printing positional deviation between forward and reverse main scanning passes is adjusted using the adjustment value. In a first adjustment mode, the adjustment value is determined by correcting the reference correction value with a relative correction value prepared beforehand for correcting the reference correction value.
