摘要： The ink jet printing apparatus forms an image on a print medium with the following two operations. The printing operation makes a print head perform scan motions in a predetermined direction on the print medium, the print head having an array of nozzle rows corresponding to the required number of ink colors, each scan motion involving the ink being ejected from nozzles onto the print medium. The print medium feeding operation moves the print medium and the print head relative to each other a predetermined amount in a direction different from a direction of the scan motion between the scan motions. In a print mode using a small number of ink colors employed for printing, unidirectional printing is performed such that the nozzle row of a black ink to be ejected reaches a print start position when amplitude of vibration of the print head is a predetermined amount or less.

摘要： In a recording medium selecting step, a recording medium on which an image is to be formed is selected from among a plurality of recording media having unique color tones. In a mode setting step, it is determined whether the image is to be output in a monochrome mode. In a signal converting step, a luminance signal corresponding to the image is converted into a density signal when the monochrome mode is set in the mode setting step. In a forming step, an image is formed on the recording medium selected in the recording medium selecting step according to the density signal. The signal converting step is controlled so that a color tone of an intermediate-density portion of the image formed on the recording medium is set to be near a*=A in the a*b* plane of the CIE-L*a*b* space, where A is a constant.

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 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： 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： A scanner head cartridge is constituted by a lower case which houses optical parts required for reading and electrical parts required for image processing, and an upper case which can engage with the lower case to cover the open surface of the lower case, and a positioning guide means used upon inserting the cartridge into the carriage is formed on the surface of the upper case, that is opposite to the lower case. A scanner head cartridge is held on a carriage that moves an ink head cartridge of an ink-jet printer for performing recording on a recording medium, in place of the ink head cartridge, and can be commonly used using a common base unit even in carriages which mount different ink head cartridges and have different shapes. In addition, the scanner head cartridge allows easy adjustment of the optical system.

摘要： In image processing it is possible to adequately reduce density unevenness and graininess according to the duty of the image data. More specifically, when dividing multi-valued data and generating 2-pass multi-pass printing data, in addition to the divided multi-valued data for each of the two passes, divided multi-valued data that is common to both of the two passes is also generated. Moreover, the quantized data of that common multi-valued data is reflected on the quantized data of each pass. Furthermore, when generating quantized data, the division ratio when generating common data in the division of multi-valued data is set according to the duty (gradation value) of the multi-valued data. By doing so it becomes possible to adequately reduce the density unevenness and graininess according to the duty of the image data.

摘要： In an overlapping head including a plurality of recording head chips overlapped to each other, a color shift can occur between a color recorded by an overlapping region and a color recorded by a non-overlapping region, which cannot be corrected by a density correction using head shading or the like. To correct such a color shift, a test pattern is recorded by the overlapping region and the non-overlapping region and colors of the recorded test pattern are measured. Color correction data to be used in correction of colors of an image to be recorded is generated based on a result of the measurement of the colors.
