摘要： For a horizontally arranged head in which nozzle rows are arranged parallel with a scanning direction of the print head, two of a plurality of ink colors used which have the largest hue difference are selected. Then, between the nozzle rows for these two colors, at least two nozzle rows for other colors are arranged so that the first nozzle row for the two colors have a large inter-nozzle-row distance. Then, the resulting print head is used for printing. If cyan, light cyan, magenta, light magenta, yellow, and black are used as ink colors, the light cyan, black, yellow, and light magenta inks are arranged between the cyan and magenta inks, having a large hue difference.

摘要： Suppressed is deterioration in image quality caused by deviation in dot forming positions between rasters in the case of carrying out printing of adjoining two rasters. The rasters are printed by two columns of ejection openings array disposed on an ink-jet head. The two columns of ejection openings are shifted from each other by a half of a pitch at which the ejection openings are arranged in the column. When allocating input image data quantized into multi-valued levels to 2 × 2 dot array as pseudo half-tone processing before printing, the mutually different plural dot arrangements are applied concerning each level of the input image data, and the plural dot arrangements are cyclically changed in the main scanning direction according to predetermined rules, and also equalization processing for equalizing the number of said adjoining the two raster dots is properly performed in the one cycle. Thus, differences in a covering ratio of the printing medium with formed dots can be put to 10% or less in a range where the adjoining two rasters are deviated from each other by at least ±2 pixels in the scanning direction.

摘要： This invention relates to an ink-jet printer equipped with an ink-jet printhead and a control method and apparatus for the ink-jet printer. The printhead incorporates an EEPROM (1008) storing head information including the ink discharge amount characteristics of the printhead. The head information stored in this EEPROM is transmitted from the ink-jet printer having the printhead to the printer driver of a host computer. The printer driver then selects a gamma correction table (3010) in accordance with the head information. In this case, a gamma correction table is selected from a plurality of gamma correction tables in which pieces of correction information which make print densities uniform are stored in correspondence with ink discharge amounts. This table also includes correction data for correcting an increase in ink discharge amount to prevent blurring due to an increase in ink discharge amount with a rise in the temperature of the printhead.

摘要： To make it possible to print a smooth image without color irregularity at a high speed by a printing apparatus using a color ink-jet head provided with plural arrays of ink ejection openings side by side in the direction of the main scanning corresponding to different color inks, moving this head to scan reciprocally, and also adopting a multi-pass printing method for divided printing on a certain area by scanning at plural times with the color ink-jet head. In the multi-pass printing using the color ink-jet head, an ink firstly landed on a certain area determines a prioritized color influential on the color tone. Moreover, a printing medium is largely covered by a first two-pass printings. Namely, if it is possible to suppress the color irregularity in the first two passes, a harmful influence on a whole image by the color irregularity can remarkably reduced, therefore, the first pass data printing ratio to the area is set smaller than that of the second pass and thereafter.

摘要： Multi-valued image data (501) corresponding to a pixel area is divided into first scanning multi-valued data (502), first and second scanning common multi-valued data (503), and second scanning multi-valued data (504). A quantization processing is executed on each of the multi-valued data (502 to 504) to generate first scanning quantized data (505), first and second scanning common quantized data (506), and second scanning quantized data (507). After that, these pieces of quantized data (505 to 507) are combined for each scanning to generate first scanning combined quantized data (508) and second scanning combined quantized data (509). According to this, the amount of pixels where dots are both recorded by performing a scanning by plural times (the amount of overlapping dots) is controlled, and while suppressing the image density variations, the granularity is held to a low level.

摘要： Printing can be properly performed on a print medium other than print media preset in accordance withprintmodes of a printer. Specifically, when the print medium other than the print media preset in accordance with the print modes is used, patches are printed on the print medium in each combination of the ink ejection amount and the number of passes, and information regarding each evaluation of granularity and banding based on colorimetry of the patches is obtained for each combination of the ink ejection amount and the number of passes. Next, a combination of the maximum ink ejection amount and the maximum number of passes is selected from the combinations that each evaluation of the granularity and the banding satisfies a certain level (202 to 212). Then, a print mode having a combination nearest the combination is selected from the plurality of print modes (213 to 215).

摘要： In an ink-jet printing apparatus which includes a plurality of printing heads (IJH) each having an array of ink discharging elements, preliminary discharge of driving the elements of at least one printing head is performed a predetermined number of times as a unit in performing preliminary discharge of discharging ink irrelevant to printing. The printing head for which the preliminary discharge is to be performed is switched to other at least one printing head in a predetermined cycle (T 11 ). In performing the preliminary discharge and switching of the printing head are so controlled as to perform preliminary discharge a desired number of times for all the elements of the printing heads by repeating the cycle.
