    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: After a first scan in a forward direction, conveying corresponding to one nozzle block is performed, and then in a second scan in a backward direction, printing of a “printing area 1,” which is a unit area, is completed. Then after completion of printing of the unit area, conveying corresponding to 14 nozzle blocks is performed. Then by reciprocal third and fourth scans, printing of a “printing area 2” is completed in a likewise manner. Subsequently, two scans in a reciprocal manner are performed in a likewise manner to perform printing of each unit area. In any unit area, printing time intervals between scans are such that, at a same position in a scan direction, the time interval is the same. Consequently, differences in density between unit areas that are adjacent in a conveying direction of a printing medium, that is, between-band unevenness becomes more difficult to recognize.

    摘要: Even if an error occurred in a result of the detection by an optical detecting mechanism for optically detecting whether or not a remaining amount of ink in an ink tank is equal to or less than a predetermined amount, a correct situation of the remaining ink amount in the ink tank can be detected. A detecting method has a first discriminating step of discriminating whether or not a remaining ink amount in the ink tank is equal to or less than a predetermined amount by using an optical sensor and a second discriminating step of discriminating whether or not the remaining ink amount in the ink tank is equal to or less than the predetermined amount on the basis of information regarding an amount of ink consumed in the ink tank. If the absence of ink is determined in either the first or second discriminating step, information showing the absence of ink is notified.

    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.
