摘要： In image processing, it is possible to suitably reduce density unevenness and graininess according to the ink used in printing. More specifically, when dividing multi-valued data and generating data for 2-pass multi-pass printing, in addition to divided multi-valued data for each of the two passes, divided multi-valued data that is common to the two passes is also generated. Moreover, quantized data of that common multi-valued data is reflected on the quantized data for each of the passes. Furthermore, when generating the quantized data, the division ratios used when generating the common data using the aforementioned multi-valued data division are set according to the colors of ink used in printing. By doing so, it becomes possible to suitably reduce density unevenness and graininess according to the colors used in printing.
摘要翻译：在图像处理中，可以根据印刷中使用的油墨适当地减小浓度不均匀性和颗粒性。更具体地说，当分割多值数据并产生用于2遍多遍打印的数据时，除了两次通过中的每一个的分割多值数据之外，还可以将两次通过的共同的分割多值数据生成。此外，该通用多值数据的量化数据反映在每个通过的量化数据上。此外，当生成量化数据时，根据在打印中使用的墨的颜色来设定使用上述多值数据分割生成公共数据时使用的分割比。通过这样做，可以根据印刷中使用的颜色适当地减小浓度不均匀性和颗粒性。

摘要： For calibration, a patch pattern is printed which enables patches to be measured while precisely reducing the adverse effects of a variation in patch pattern density resulting from a variation in movement speed or temperature of a printing head. Specifically, dummy patches that are not measured are printed on the periphery of measured patches. The dummy patches are printed by ejecting ink through all ejection openings in the printing head. Then, an increased dye concentration of ink is discharged from the printing head. Further, at the ends of a scanning range, at which the dummy patches are printed, the movement speed of the printing head varies significantly. Accordingly, the measured patches can be printed while the speed remains stable.

摘要： Disclosed are a method and apparatus for forming a color transform lookup table which helps output a smooth image having no pseudo contour and excellent in granularity. On the basis of a previously formed table, a color space is expressed by a basic triangle of white-primary color-black, and output signal values corresponding to lattice points in this basic triangle are calculated by linear interpolation. Black ink and cyan ink are replaced by setting a straight line AB, as a boundary line, connecting two points immediately before black ink begins to be introduced on two sides of the basic triangle.

摘要： An image process method comprises an input step of inputting color image data composed of a signal representing brightness and a signal representing tint, and a smoothing process step of performing a smoothing process to the signal representing tint, while holding the signal representing brightness. Thus, high-level color noise reduction can be performed without deteriorating apparent resolution of an output color image.

摘要： When a color reproduction model of a device is generated, colorimetry of a 9×9×9 grid, for example, is performed utilizing equidistant signal values in the color space of the device. Generally, if the number of grid points is increased, the precision with which the color reproduction model is estimated rises but the time needed for measurement is prolonged because the number of colorimetric measurements is also increased. Accordingly, in a printer system comprising a pre-color-processing table for performing color matching and a post-color-processing table for performing color separation, color patches set non-equidistantly in RGB device color space are printed in accordance with changeover of printer CMYKcm signals in the post-color-processing table and the color reproduction model of the printer is generated using data obtained by measuring the colors of the color patches.
摘要翻译：当产生装置的色彩再现模型时，例如使用装置的色彩空间中的等距信号值来执行9×9×9格栅的比色法。通常，如果增加网格点的数量，则颜色再现模型的估计精度会上升，但由于比色测量的数量也增加，所以测量所需的时间延长。因此，在包括用于执行颜色匹配的预色处理表和用于执行颜色分离的后色处理表的打印机系统中，根据打印机的切换来打印在RGB设备色彩空间中不等距设置的色标使用通过测量色标的颜色获得的数据，生成后色处理表中的CMYKcm信号和打印机的颜色再现模型。

摘要： When a printing apparatus performs printing using dark and light inks, a large variation in density caused by a rapid decrease in ink applying rate is prevented, thereby enabling proper density reproduction. More specifically, when for example, green hues of different densities are printed, light cyan ink is used between points corresponding to a variation of color from white to green. Furthermore, after the maximum saturation point, light cyan ink is used in addition to the dark cyan ink. This prevents the total applying rate from decreasing rapidly near the maximum eaturation point.

摘要： A process of detecting a defective recording element and a process of correcting the defective recording element are performed with appropriate processing loads. When the detection process and the correction processes are performed with small loads, for example, at a time of recording, a resolution used for reading an inspection pattern is set lower than that set in a case where the processes can be performed with small loads, for example, at down time before recording. The reading resolution to be set may be determined by an apparatus in accordance with a processing load or may be arbitrarily determined by a user.
