摘要： An object of the present invention is to provide an ink jet print head having plural types of nozzles arranged on the same substrate and through which ink droplets of different sizes are ejected, the ink jet print head exhibiting acceptable ejection performance regardless of the type of the nozzle. Thus, according to the present invention, each of the plural types of nozzles includes a bubbling chamber having an ejection energy generating element allowing an ink droplet to be ejected to a position located opposite an ejection port and an ejection port portion allowing the ejection port and the bubbling chamber to communicate with each other. Ratio of opening area of the ejection port portion at a position where the ejection port portion and the bubbling chamber communicate with each other, to the opening area of the ejection port is higher for the nozzle with a smaller ejection amount.

摘要： A dark color (for example, cyan) ink dot formed by preliminary ejection can be made less noticeable, and the influence on the printing quality can be reduced, even in a case where the dark color ink is preliminarily ejected onto a light color (for example, yellow) image area. For this purpose, in a case where the dark color ink is preliminarily ejected onto the image area of high lightness, the amount of the ink applied for printing the area is reduced. For example, in a case where a cyan ink is preliminarily ejected onto an area to be formed of yellow dots, a piece of data for forming the yellow dot in the preliminary ejection position is deleted. This reduces an overlapping area of the yellow area and the ink dot formed by the preliminary ejection, and thus makes the ink dot formed by the preliminary ejection less noticeable.

摘要翻译： 通过初步喷射形成的深色（例如青色）墨点可以变得不太明显，即使在深色墨水被预先喷射到浅色的情况下也可以降低对打印质量的影响（对于 示例，黄色）图像区域。 为此，在深色油墨预先喷射到高亮度的图像区域的情况下，用于打印该区域的油墨的量减少。 例如，在将青色墨预先喷射到要由黄点形成的区域的情况下，删除在预喷射位置形成黄点的数据。 这样可以减少黄色区域和通过预喷射形成的墨点的重叠区域，从而使由初步喷射形成的墨点不太明显。

摘要： The present invention provides a print head that ejects ink supplied through an ink supply port so as to prevent the size of satellites from being reduced while inhibiting an increase in resistance to an ink flow. In the print head, ink supply ports are arranged on both sides of a plurality of channels. A predetermined number of ink supply ports are arranged at least one side of the ink channel all over the range of the arrangement of the channels. One side of each of the plurality of channels is connected via the common liquid chamber to the liquid supply port located so as to extend in a direction in which the channels are arranged.

摘要： A recording head has a channel forming member and an element substrate. A discharge port through which liquid is discharged is formed in the channel forming member. An energy generating element for discharging the liquid is formed in the substrate. A gap forming member is arranged above the channel forming member. A moisture retention liquid retention portion which retains moisture in the vicinity of the discharge port is formed between the gap forming member and the channel forming member so as to be opened toward the discharge port side. Even if the state in which the liquid is not discharged continues, the liquid in the discharge port can be prevented from drying with the recording head having the above configuration.

摘要： An ink jet head includes a substrate provided with heat generating members for generating a bubble in ink on a surface of the substrate, a plurality of discharge ports for discharging the ink, the ports opposed to the surface of the substrate, and a plurality of ink flow passages communicating with the plurality of discharge ports to feed the ink. A plurality of the heat generating members is provided in each of the ink flow passages, and the discharge port is arranged on an extension line extending from a center of a pressure generating area composed of the plurality of heat generating members toward the surface of the substrate in a normal direction. Moreover, a distance dhc between centers of each of two heat generating members arranged most apart from each other among the plurality of heat generating members is set to be larger than a diameter do of an aperture of the discharge port. In the ink jet head, even if the center position of the discharge port and the center position of the pressure generating area are somewhat shifted from each other, main liquid droplets of the ink are discharged from the discharge port without generating no shift in their discharge directions.
