摘要： In a multi-valued printer that uses discontinuous index patterns, if a tone correction table is generated using sampled density patches, a table which is different from a table to be obtained and has no inflection point is obtained, and the print density characteristics after tone correction suffer discontinuity. To solve this problem, an output gamma table used to output measurement patches is set to linearly correct the printer print characteristics. Patches are output and their densities are measured. A reverse table of a “signal value—density” table is generated, and is smoothed using a recursive curve. The smoothed reverse table is finely adjusted to generate an intermediate output gamma table. The generated table undergoes index component correction, thus generating a tone correction table.

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： This invention relates to an ink jet recording apparatus and a recording method for recording images of high dignity with the amount of ink placed per unit area of a recording medium being always kept constant even if the resolvability when recording is effected changes. When the amount of ink of an ink droplet discharged from a recording head is constant (25 pl), the average number of recorded dots conformity to the resolvability is found on the basis thereof, and the number of recordable dots is found from this average number of dots. The difference between this number of actually recorded dots and the average number of recorded dots is adjusted by reducing the value of recording data in advance.

摘要： By ejection from each ejection opening of a liquid ejecting head, predetermined lengths of ruled line patterns are formed in order, and by ejection of an ink from an ink ejecting head, a solid pattern is printed overlaying the ruled line patterns of the liquid. In this case, the portion corresponding to the ejection opening through which the liquid cannot be ejected may be a different printing density in comparison with another portion where the liquid and the ink are overlaid. By this, non-ejection failure at the ejection opening can be detected. Therefore, in an ink-jet printing apparatus employing a head for ejecting the liquid for making a coloring agent in the ink insoluable for enhancing water resistance, the ejection condition of the head can be successfully detected.

摘要： When dividing multi-valued data and generating data for two-pass multi-pass printing, in addition to divided multi-valued data that are divided for each of the two passes, divided multi-valued data that is common to both of the two passes is generated. Moreover, quantized data of that common multi-valued data is reflected onto the quantized data for each pass. Furthermore, when generating quantized data, division ratios that are used when generating the common data by the multi-valued data division described above are set according to the image characteristics (whether or not the area is flesh color) of the multi-valued data. Thereby, it is possible to perform high-quality printing regardless of the image characteristics by taking a suitable balance between suppressing density unevenness and suppressing graininess.
