摘要： The use amount of clear ink is set to minimize the hue difference Δθs−d from each of the colors corresponding to input signal values. The use amount of the clear ink to provide the minimum hue difference Δθs−d is varied depending on the use amount of color ink used for the color corresponding to the input signal value. A color conversion table having output values of the use amount and ink color data corresponding to the use amount is set. The color conversion in such a relationship is performed, whereby the bronzing color is recognized as a color close to the print color. As a result, undesired bronzing is lessened, so that degradation in image quality can be suppressed.

摘要： An ink jet recording apparatus is structured to perform discharges in the capping status when preliminary discharges are performed in a shot number larger than a predetermined number, and perform discharges in a cap or a preparatory port other than the cap when the preliminary discharges are performed in a shot number less than the predetermined number. With the structure thus arranged, it is made possible to implement the suppression of the mist generation due to the preliminary discharges, and to make the time of recording on a recording medium shorter as well.

摘要： The invention prevents a pattern arising from periodicity of dot arrangements from appearing as noise, such as a streak, when a plurality of different dot arrangements are used repeatedly in a unit of a predetermined number of the dot arrangements for the same level of gradation of input image data, and thereby makes it possible to print a high-quality image. To this end, when input image data quantized to one of multivalued levels of gradation is allocated to a dot arrangement of M×N, a matrix of A×B created by combining a plurality of different dot arrangements each displaying the same level of gradation of the input image data in a raster direction and in a column direction is used as a minimum unit, and the dot arrangement of this matrix is allocated to the input image data.

摘要： The first printing mode improves gloss uniformity by setting the colorless ink discharge amount to be equal to or smaller than a reference value A at a dark image portion in input image data, and performing normal discharge printing in which printing with a colorless ink starts before completion of printing with a color ink (FIG. 11C). The second printing mode implements a wide color reproductive range by setting the colorless ink discharge amount to be larger than A at the dark image portion, and performing post-discharge printing in which discharge of the colorless ink starts after completion of printing with the color ink (FIG. 11D).

摘要： An ink-jet recording apparatus for effecting recording using an ink-jet recording head is capable of forming large dots and small dots. The number of times of discharge operation for forming large dots and the number of times of discharge operation for forming small dots are separately counted, and a total ink discharge amount is calculated on the basis of these count values. The total ink discharge amount which is compared with a predetermined value to perform appropriate suction processing. According to the invention, an ink suction operation from a discharge port is started with appropriate timing, thereby controlling consumption of ink.

摘要： An image processing method includes the steps of converting input image data to ink color data corresponding to each amount of a plurality of colors of achromatic inks used for printing, and generating printing data for first, second and third achromatic inks based on the ink color data. The printing data is used for printing by causing a printing head to scan a common image area in a printing medium a plurality of times, the printing head ejecting the plurality of colors of inks. The converting step converts the input image data to ink color data for the first, second and third achromatic inks so that the first achromatic ink is used with respect to a value of the input image data indicating achromatic color, and the generating step generates the printing data for the first, second and third achromatic inks so as to (a) make a printing duty for the first achromatic ink during first half of the plurality of scans higher than a printing duty for the first achromatic ink during the latter half of the plurality of scans, and (b) make printing duties for the second and third achromatic inks during the latter half of the scans higher than in the first half of the scans.
