摘要： A printing apparatus and a printing method define an achromatic region and a chromatic region of image data. The image data is defined as an achromatic region when a difference between a maximum and a minimum values among R, G, B values corresponds to 1% to 10% of a range of values that R, G, B values are obtainable. In the achromatic region, the number of black and its derivative ink dots to be ejected per one pixel is 4 dots at the maximum. A chromatic region is defined as an area where does not satisfy the requirements of the achromatic region. In the chromatic region, the number of black and its derivative ink dots to be ejected per one pixel is 1 dots at the maximum.

摘要： A recording system can take the form of a recording apparatus, a recording method or a program to control the recording apparatus for recording a color image on a recording medium by utilizing a recording head on which a plurality of recording elements are arranged. The recording system uses a plurality of compensation methods to compensate a position to be recorded by a recording element which does not execute a recording operation among the plurality of recording elements and selects an appropriate compensation method. Such recording system can resolve nonuniformity in the recorded image such as white streaks and the like generated by non-eject dots and can make the nonuniformity be unrecognized by the human eye. In addition, the recording system can suppress increase in costs of the recording head and can significantly increase recording rates.

摘要： In an image area printed by a nozzle group including a defective nozzle, pixels printed by the defective nozzle and part of pixels located in the vicinity of the same are printed by another nozzle group. As a result, since printing is performed not only at the pixels printed by the defective nozzle but also at the pixels in the neighborhood thereof simultaneously by separate nozzles, irregularities of printing attributable to interpolation are distributed even when there is a relative misalignment between the nozzle groups. It is therefore possible to obtain a preferable image without any increase in output time even when a printing head including a defective nozzle is used.

摘要： A secondary color is used for printing an image with a printer so as to reduce the granularity of the printed image, particularly the light image area. Data of magenta and cyan color components of image data is subjected to under-removal processing to generate blue ink image data as the mentioned secondary color. A blue ink dot is printed in accordance with the blue ink data obtained by the under removal processing to replace the magenta and cyan data. As a result, it is possible to reduce the granularity that would otherwise be caused by localized distributions of magenta and cyan dots.

摘要： An ink jet printing method and apparatus using a color ink and a print performance improving ink which minimizes an image quality degradation due to blank lines formed by failed or faulty nozzles. This system enables the use of a print head even with failed or faulty nozzles by minimizing the image quality degradation and extends the life of the print head before replacement. The print performance improving ink is not ejected and landed near a blank line, thus allowing the color ink dots near the blank line to spread and thereby making the blank line undistinguishable.

摘要： A recording apparatus includes a recording head for performing recording on recording paper, the recording head having three or more types of inks of different densities but of the same color. A combination of the inks used to record a pixel of a grayscale image, which is to be recorded on the recording paper, is decided based upon the pixel by a data distribution unit which refers to ink density data and combination data. Recording by the recording head is controlled, based upon the combination of inks decided, by a unit which controls the recording head and paper feed.

摘要： A recording system for recording a color image on a recording medium by utilizing a recording head, on which a plurality of recording elements are arranged, includes a compensation unit to compensate a position to be recorded by a recording element which does not execute a recording operation by color dots different from those of that recording element. The compensation unit is controlled such that the number of the compensation dots is less than the number of dots to be formed originally and that lightness per a determined area of an image obtained by the compensation dots is within a range of ±20% of that to be obtained by dots from the recording element which does not execute the recording operation. The recording system can minimize nonuniformity in the recorded image, can make the nonuniformity be unrecognized by human eyes and can suppress increased costs while increasing recording rates.

摘要： When multilevel printing is performed by using a plurality of types of inks, which present different densities for similar colors when used for printing, and changing the types of inks and the numbers of ink droplets in printing each pixel, an ink distribution table which defines a combination of the types of inks and the numbers of ink droplets in correspondence with each gray level value is generated on the basis of input information associated with the relative densities of the respective inks. A combination to be used to print each pixel is selected on the basis of the ink distribution table, thereby printing a good grayscale image free from gray-level reversal and the like.
