摘要： The present invention provides a liquid ejection head for which the peeling of an orifice plate from a substrate seldom occurs, even in a structure such that the walls that define each energy application chamber are narrowed toward an ejection port. The walls that define a first pressure chamber are inclined inward within the first pressure chamber, so that the first pressure chamber is narrowed, toward an ejection port, along a direction perpendicular to the heater formation face on which heaters are arranged. Further, the walls that define each ink flow path are inclined in the ink ejection direction. Furthermore, the angle at which the walls that define the ink flow path are inclined relative to the ink ejection direction is smaller than the angle at which the walls that define the first pressure chamber are inclined inward, within the first pressure chamber.

摘要： An ink jet printing apparatus and an ink jet printing method are provided which, when printing small ink droplets at high resolution, can make white lines caused by an “end dot deflection” less visually conspicuous. To that end, an ink jet print head used has a plurality of nozzle substrates arranged that an overlapping region in which the printable areas of respective nozzle substrates partly overlap is formed. According to a print density to be achieved, each of the nozzles corresponding to the overlapping region is controlled for ejection/non-ejection of ink. With this method, it is possible to print as many dots as most match the intensity of the “end dot deflection” phenomenon that varies according to the print density. This enables a blank line to be filled with an appropriate number of dots at all times, regardless of the width of the blank line.

摘要： An ink jet head movable in a main scan direction includes first and second groups of ejection outlet arrays disposed on either side of a common liquid chamber and including plural ejection outlet arrays. In the first group, amounts of liquid ejected from outlets of first and second ejection outlet arrays, which are staggered, differ from each other. In the second group, a common ejection amount ejection outlet array ejects the same amount of liquid as that of one of the first and second ejection outlet arrays and a non-common ejection amount ejection outlet array ejects an amount of the liquid that differs from that of the first ejection outlet array group. The ejection outlets of the common and non-common ejection amount ejection outlet arrays are disposed in a staggered arrangement. The ejection outlets of the second ejection outlet array group are disposed with deviation of ½ of an interval at which the ejection outlets of the first ejection outlet array group are arranged. Different sets of the same cyan and magenta colors in the non-common ejection amount ejection outlet arrays are disposed with deviation of ½ of an interval at which the ejection outlets of the non-common ejection amount ejection outlet arrays of other sets are arranged.

摘要： A method is provided which is intended to reduce a visibility of ink dots ejected onto a print medium during a preliminary ejection operation to produce a satisfactory printed image. Preliminary ejection data is compared with image data. When the preliminary ejection necessary to performed on a pixel that has no image data, image data of a pixel close to the pixel being processed is searched. When image data exists, the image data is moved to a pixel that has preliminary ejection data. The preliminary ejection data is added to the image data one scan at a time to perform printing.
