摘要： In an image processing for printing a monochrome image, color deviation can be suppressed to print a favorable monochrome image. Specifically, the printing of a monochrome image is performed by using black ink in all of a color reproduction region (color gamut) including a gray axis and regions other than the gray axis. This avoids the use of C, M, and Y for the expression of the monochrome image to suppress the color deviation due to slight imbalance among amounts of three colors of inks.

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： 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： 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： 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.
