摘要： According to the present invention, each printing head includes chips wherein a plurality of nozzles are prepared. The density of dots formed by ejecting ink from the nozzles is detected for each chip, and when a density difference between the chips is smaller than a predetermined value, print data are corrected, and the number of dots is adjusted so as to reduce the density difference. When the density difference is equal to or greater than the predetermined value, first, a drive pulse for the nozzles is modulated and the volume of ink to be ejected for one dot is adjusted so as to reduce the density difference. Thereafter, the print data is corrected, and the number of dots to be formed is controlled so as to reduce the density difference.

摘要： A high quality gray scale (monochrome) image in which influences of “recorded color deviation” and “color transition” are suppressed is formed even in the case of a slightly uneven discharge amount. When a gray scale (monochrome) mode is set, in the entire range of a luminance signal, density signals corresponding to achromatic dots and small chromatic dots respectively are generated based on the luminance signal so that the density signal corresponding to the achromatic dots has a greater value than that of the density signal corresponding to the small chromatic dots. Accordingly, even a slight “recorded color deviation” that occurs when the achromatic dots are recorded can be corrected by the small chromatic dots having a hue opposite to the direction of color deviation, and a high quality gray scale image in which influences of “recorded color deviation” and “color transition” are suppressed can be formed.

摘要翻译： 即使在稍微不均匀的放电量的情况下也形成了其中抑制了“记录色差”和“色彩转变”的影响的高品质灰度（单色）图像。 当设置灰度（单色）模式时，在亮度信号的整个范围内，分别基于亮度信号产生对应于无色点和小色点的浓度信号，使得与无色点相对应的浓度信号具有 比对应于小色点的浓度信号的值更大。 因此，即使在记录了无彩色点时发生的轻微的“记录颜色偏差”也可以通过具有与颜色偏差方向相反的色调的小色点校正，并且可以通过高质量灰度图像来校正“记录 颜色偏差“和”颜色转变“被抑制。

摘要： The color of magenta using newly developed magenta ink has characteristics L*≅41, a*≅82, and b*≅24, and has differences ΔL*≅4, Δa*≅0, and Δb*≅26 from the conventional magenta ink, i.e., the lightness value is low, and the color difference b* assumes a very small value. When the color of red is reproduced using such new magenta ink, its lightness and saturation values are low, and subdued red is reproduced, i.e., a visually favorable color cannot be obtained. Hence, when a color included in a first color gamut is input, and the input color is converted into the color of a second color gamut narrower than the first color gamut, color conversion is made using a three-dimensional lookup table having red defined by. L*≅45 to 50, a*≅67 to 70, and b*≅50 to 55.

摘要： The gray axis is adjusted such that an optimal representation can be achieved for low saturation colors close to the gray axis. A test pattern including a plurality of images, which have different color tones is printed, and a user selects a most desirable image. The gray axis of an image recording system is adjusted depending on which image is selected. Each of the plurality of images of the test pattern is a photographic color image represented mainly by low saturation colors close to achromatic colors along the gray axis. In accordance with the selected image, the gradation adjustment is performed for each ink color of the image recording system thereby adjusting the gray axis and the tone of colors close to the gray axis.

摘要： An in ink jet printing method and apparatus are disclosed which prevents mixing of ink with a liquid insolubilizing and/or agglomerating the ink and which can print images having excellent water resistance and high quality. Prevention of mixing of the ink with the liquid is achieved by separately arranging an ink receiver for receiving ink ejected by preliminary ejection and the liquid insolubilizing and/or agglomerating the ink ejected by preliminary ejection, or by setting the distance between the ink jet cartridge for the liquid and the cartridge for ink adjacent thereto is made larger than the distance between two adjacent ink jet cartridges. Alternatively, the direction of ejecting ports of an ink jet ejectors may be deviated. Prevention of mixing may also be achieved by using in addition to printing head ejecting ink onto a printing material, a printability improving liquid ejecting head ejecting a printability improving liquid which insolubilizes and/or agglomerates the coloring material in the ink, and recovering units for recovering the heads. Also, mixing of the ink with the liquid is prevented upon capping, wiping, suction recovering.
