摘要： An image recording apparatus includes liquid ejection heads, wipers, and a movement means. The liquid ejection heads respectively have ejection faces, and are arranged in such a manner that the ejection faces form two rows extending in one direction and in addition two of the ejection faces included in different rows do not overlap each other along a direction perpendicular to the one direction. The liquid ejection heads are divided into one or more head groups each including two of the liquid ejection heads corresponding to the different rows. The movement means moves two of the wipers associated with two liquid ejection heads belonging to each head group, from inner end portions of the ejection faces in opposite directions along the perpendicular direction while keeping the two wipers in contact with the ejection faces.

摘要： Pressure fluctuations that occur inside an ink jet head will be controlled. The ink jet head has a body. A common ink storage chamber is formed inside the body. A plurality of nozzles and a plurality of pressure chambers are formed in the surface of the body. One nozzle corresponds to one pressure chamber, and one pressure chamber corresponds to one nozzle. A plurality of individual ink storage chambers are formed inside the body. Each individual ink path extends from the common ink storage chamber, through one corresponding pressure chamber, and to one corresponding nozzle. The ink jet head is provided with an adjustor that allows the volume of the common ink storage space to increase or decrease. When the pressure of the ink that is stored in the ink jet head fluctuates, the volume of the common ink storage space will increase or decrease, and the pressure fluctuations will be smoothed.

摘要： A region for quantization having a value lower than the value B is assumed as having little influence by Bk data on the pixels in this region. Thus, in order to prioritize the optimization of the granularity at the start of the input of GY data, the LUT having a combination of GY and gy as an input as an input is used to perform separation quantization. On the other hand, since a region having a value equal to or higher than the value B requires the use of Bk data, the LUT having only a combination of Bk and GY as an input as an input is used to perform quantization. As a result, the number of types of pieces of ink data referencing the table can be 2, thus suppressing an increase in the table size.

摘要： In an inkjet printing method of performing printing on a printing medium by ejecting inks from a printing head configured to eject chromatic inks and an achromatic ink while moving the printing head, high-quality printing with few boundary stripes produced when the amount of inks is large is realized without complicated control being performed. To this end, print data in a boundary and the vicinity thereof is divided into unit regions, and for each unit region, performed are (A) a first reduction processing which determines a hue of the unit region based on amounts of the chromatic inks, and reduces the amount of chromatic inks applied to the unit region according to the determined hue; and (B) a second reduction processing which reduces an amount of achromatic ink based on the amount of achromatic ink applied to the unit region.

摘要： An inkjet head includes a flow path unit and a reservoir unit. The reservoir unit stores ink and includes an ink flow path, a reservoir flow path and an ink drop flow path. The reservoir flow path includes a main flow path formed with plural tributary communication ports, and plural tributary flow paths. A section area of the main flow path taken along a width direction of the reservoir unit is larger than each of section areas of the tributary flow paths taken along a direction perpendicular to a flow direction of ink. The ink drop flow path drops ink onto a substantially center of the main flow path as viewed in a plan view. The tributary communication ports are substantially equal to each other in an opening area.

摘要： The present invention reduces image deterioration such as density nonuniformity when recording is performed using a recording head having two ejection orifice rows that eject a predetermined achromatic ink, for example, gray ink. For this purpose, the distance between two ejection orifice rows that eject a predetermined achromatic ink is larger than the distance between two ejection orifice rows that eject a predetermined chromatic ink.

摘要： An ink jet printing apparatus is provided which is capable of producing an image with a good balance between image quality and printing speed, without unduly shortening a longevity of a print head, even when an odd-numbered-pass bidirectional printing is performed. To this end, during a bidirectional multi-pass printing with a relatively small number of passes, a stepping mask is used to eliminate image problems caused by a difference in print permitted ratio between forward scan and backward scan. During a bidirectional multi-pass printing with a relatively large number of passes, a flat mask is used to give priority to suppressing density unevenness resulting from nozzle characteristic variations. As a result, the printing apparatus as a whole can produce an image with a good balance between image quality and printing speed, without unduly shortening a longevity of the print head.

摘要： An ink jet printing apparatus and an ink jet printing method are provided which are capable of minimizing image impairments caused by a bias of satellite positions even when an odd-numbered-pass bidirectional multi-pass printing is performed. To this end, in an odd-numbered-pass bidirectional printing, a mask pattern, in which print permitted pixels and print non-permitted pixels are arranged such a way that a percentage of pixels in which predetermined two inks are permitted to be printed by scans in different directions is higher than a percentage of pixels in which the predetermined two inks are permitted to be printed by scans in the same directions, is used. This increases the probability of satellites of the two types of the inks printed in the same pixels being printed on both sides of main dots, thus allowing a uniform image to be produced even by an odd-numbered-pass bidirectional printing.

摘要： According to this invention, an inkjet printing apparatus having an arrangement for detecting an amount of remaining ink in an ink tank starts a printing operation in a short time immediately after power-on. If an operation in preceding use is ended without any error at the time of power-off, and no error has occurred even at the time of power-on, the inkjet printing apparatus of this invention starts the printing operation without executing the operation of detecting the amount of remaining ink in the ink tank after power-on.
