摘要： An inkjet apparatus and a method of preventing misplacing the inkjet cartridge therein are disclosed. The inkjet apparatus comprises a carriage, a control unit and a sensor. The carriage is equipped with at least an inkjet cartridge that has an identifiable area. The color of the identifiable area is associated with the colors of ink stored in the inkjet cartridge. The sensor detects the color of the identifiable area and sends a signal to the control unit. The control unit receives the signal and determines whether the inkjet cartridge is correctly placed. If the inkjet cartridge is misplaced, a warning signal is generated to alert the user.

摘要： Selective replacement methods and systems based on a stochastic process use a redundancy inherent, for example, in a four-plus color printing system that has full-width colors. Since the absorption spectra of the four or more colors usually overlap to some extent, there is a redundancy that can be used to reduce artifacts, such as streaks. Since the human visual system is much less sensitive to chrominance changes, than to luminance changes, matching the luminance of a pixel where a color is missing, to the luminance of the original color or to the luminance of the pixels that neighbor that pixel can adequately to reduce the severity of the artifact caused by the missing color while reducing the chance that the replacing process itself introduces any additional artifacts.
摘要翻译：基于随机过程的选择性替换方法和系统使用固有的冗余，例如在具有全宽颜色的四色彩色打印系统中。由于四种或更多种颜色的吸收光谱通常在一定程度上重叠，所以存在可用于减少伪像（例如条纹）的冗余。由于人类视觉系统对于色度变化的敏感程度要比亮度变化（匹配缺失颜色的像素的亮度）与原始颜色的亮度或邻近该像素的像素的亮度相匹配以减少由缺失颜色引起的伪像的严重性，同时减少替换过程本身引入任何其他工件的机会。

摘要： A technique of the present invention uses dark yellow (DY) ink, in addition to a plurality of conventionally used basic color inks including cyan (C) ink, magenta (M) ink, and yellow (Y) ink. The technique may cause a printer to create dots with the DY ink, in place of creation of dots with the Y, C, and M inks. This arrangement enhances the degree of freedom in specification of dot on-off conditions of the respective inks, and relieves the restriction of ink duty, thereby enabling a resulting printed image to have higher picture quality.

摘要： Disclosed are color filter producing method/apparatus for producing a color filter by ejecting onto a substrate ink from an ink-jet head having a plurality of nozzles arranged substantially in a first direction while relatively scanning the ink-jet head and the substrate in a second direction substantially perpendicular to the first direction, so that filter elements adjacent in the second direction may be colored to have different colors. In the method/apparatus, before the coloring, landing locations for the plural ink dots to be ejected to color the filter elements, are measured and based on the measurement results, ejection timings for the plural nozzles are adjusted so that the plural ink dots land along the center line of each of the filter elements in the first direction. Therefore, it is possible to provide a color filter producing method whereby, during the production of a color filter using the ink-jet method, the occurrence of color mixing can be reduced, and to provide an apparatus therefor.

摘要： An ink jet recording apparatus uses a recording head having discharge ports to discharge ink, and records by discharging ink from the recording head while enabling said recording head to travel in the direction of main scan. This apparatus comprises a recording head which is provided integrally with a plurality of recording units having a plurality of discharge port arrays for discharging ink of different colors, respectively, and then, the plurality of recording units are arranged in the direction of main scan to discharge ink of different densities, respectively. With the structure thus arranged, the recording in all the colors is not executed at a time thus making it possible to obtain an excellent image with a lesser deterioration of image due to ink blur and the like.

摘要： A swath printing system and pixel depletion methods compensate for the effects of defective printing elements by adjusting the pixel depletion mask used during printing to minimize the amount and location of extraneous unprinted spaces caused by the defective printing elements. A printing element quality detector determines which printing elements are functional and which are defective. Based on this information, an image processor then selects or constructs a depletion mask having depleted pixel positions chosen to reduce the adverse effects on print quality caused by the defective printing elements, thus maintaining high image quality for the printed output. Pixel depletion is preferably performed at the image pixel level, but can alternatively be performed at the color plane pixel level.

摘要： A color ink jet recording method/apparatus is capable of reducing blurring of ink dots without reducing dot saturation, generating no difference in tones of secondary colors, and inviting no reduction of throughput, hence materializing an excellent performance of recording in high quality at high speed. A color image is formed by causing ink dots of plural colors to land in such a manner that each of the ink dots is essentially not superposed. The ink dots have the optical density of 1 or more and 1.5 or less. Thereby, overlapping between adjacent ink dots is lessened, and thus a high-quality color image having no difference in tones of secondary colors and a high saturation can be attained.
摘要翻译：彩色喷墨记录方法/装置能够减少墨点的模糊，而不会降低点饱和度，不产生二次色调的差异，并且不会降低生产量，因此以高速实现高质量记录的优异性能。通过使多个颜色的墨点以使得每个墨点基本上不重叠的方式落地来形成彩色图像。墨点的光密度为1以上且1.5以下。由此，可以减少相邻墨点之间的重叠，从而可以获得没有二次色调和高饱和度的高质量彩色图像。
