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： In an ink jet printing apparatus using many types of inks to execute bidirectional printing, if ejection opening rows for yellow, magenta, and cyan inks are symmetrically arranged, ejection opening rows for a black ink are arranged adjacent to the most inside ejection opening rows for the yellow ink. Thus, a difference in color between forward scanning and backward scanning is determined by a difference in coloring between the black ink and the yellow ink. In this case, a possible color drift attributed to bidirectional printing can be suppressed by selecting the inks so that the difference in coloring between the black ink and the yellow ink is smaller than that between the black ink and the other color inks.

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： In the ink-jet printing apparatus, the influence of displacements of printing positions caused by the excessive conveyance of a printing medium to the resultant image when the rear end of the printing medium exits from a nip portion between the roller pair in a conveying mechanism. More specifically, in the printing operation for the rear end portion of the printing medium in which the printing medium exits from the roller pair, the guide shaft for supporting the carriage is lifted at a position wherein a head-medium distance is changed to widen a distance between the printing had and the printing medium (S402). Thereby, the displacement of the landing position caused by the excessive conveyance of the printing medium is inconspicuous because of the variations of the landing positions due to the widening of the head-medium distance.
