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： An ink jet printing apparatus includes a print head that is an array of a plurality of nozzles arranged according to each color of ink in a predetermined direction. The apparatus is provided with a plurality of print modes, each using a different number of colors of ink for printing. In a print mode using a smaller number of colors of ink for printing (e.g., a monochrome print mode) out of the plurality of print modes, a print method is adopted, in which an image of a predetermined area is formed by a greater print pass count than the print pass count for the predetermined area in a print mode using a greater number of colors of ink for printing (e.g., a color print mode).

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： A high-quality monochrome photographic image is formed using a high-resolution color ink-jet recording apparatus. When a monochrome mode is selected, density signals are produced such that they include at least one density signal corresponding to a chromatic color material and a density signal corresponding to an achromatic color material and having a value greater than the value of the at least one density signal corresponding to the chromatic color material. A slight recorded color deviation that can occur when the achromatic color material is recorded on a recording medium is compensated for by adding a small amount of chromatic color material having a hue which cancels out the recorded color deviation. Thus, a high-quality gray scale image is obtained without having recorded color deviation or color transition.

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： A scanner head cartridge, which can be mounted exchangeably with an ink head cartridge on a carriage capable of moving the ink head cartridge of an information processing apparatus for recording on a recording medium, includes a lower case containing therein optical parts required for reading, an upper case structured to be coupled with the lower case for covering the open face of the lower case and guiding means arranged on the upper surface of the upper case for positioning when being inserted into the carriage. With the structure thus arranged, it is possible to mount the scanner head cartridge on the carriage by a simple mounting operation with a highly precise positioning simultaneously.
