摘要： Small dots and large dots are recorded with a sufficient difference between them by such structure that a plurality of heat generating elements are disposed inside of each nozzle. A single pulse is applied to one heat generating element for recording of a small dot, whereas a single pulse and a divided pulse are applied to two heat generating elements for recording of a large dot. When the divided pulse is applied to the heat generating element, a larger amount of the ink is ejected than upon application of the single pulse. Therefore, the sufficient difference can be generated between the sizes of dots by applying the driving pulses as described above.

摘要： Disclosed are an ink-jet printing method and apparatus for jetting ink successively from nozzles of an ink-jet head at a prescribed frequency and forming each of a number of pixels by a plurality of dots conforming to the tone of the pixel. Each nozzle of the ink-jet head has a heater A and a heater B. Printing is performed by changing the number of heaters actuated to jet an ink drop, thereby to control the formation of a large or small dot by each nozzle, and by changing the method of driving the heaters A and B in dependence upon the density of the ink used. In regard to the timings at which the large and small dots are formed by each nozzle, the small dot is formed first. As a result, the large and small dots can be made to overlap so that an image having excellent tone reproducibility can be printed.

摘要： Two sets of recording heads for applying ink of cyan (C), magenta (M), and yellow (Y) are arranged in symmetry in a scanning direction and orders of colors C and M ejected onto a pixel of a secondary color are set to symmetric orders (C→M and M→C). This makes the application orders of ink symmetric in each pixel of secondary color and thus there is no difference between application orders in formation of the pixel by either forward or backward scanning, whereby occurrence of uneven color due to the application orders of ink can be reduced even in execution of two-way color print.

摘要： An apparatus and method capable of obtaining an output characteristic of the print unit and determining a correction value for an output density, without using an expensive scanner. To realize this, a nozzle array consisting of a plurality of nozzles provided in the print head is divided into a plurality of nozzle blocks [a] to [d] and each of patches is formed by using the nozzles of the same nozzle block allocated to the patch. The patches are printed in a size and shape that allows the densities of the patches to be optically detected by the density sensor. A test pattern comprising these patches is measured by the density sensor to make a density correction for each nozzle of the print head.

摘要： The present invention reduces a difference in speed between a main drop section and a tailing section of a ejected ink droplet by heating a front heater and a rear heater provided for one nozzle with a predetermined time lag and thus, the ink dot formed from the main drop section and the tailing section on a printing medium can be more approximate to a circle. Thereby, it is possible to prevent print quality from being degraded by the tailing section separated from the main drop section of the ink droplet ejected from an ink jet printing apparatus of serial type.

摘要： In a printer, when difference in ejection characteristic among nozzles appears as density non-uniformity and the way of letting the density non-uniformity appear is different depending upon kind of image, proper density correction is performed. Specifically, the kind of image to be printed is judged, and when the kind of image is a halftone image according to the judgment, a density correction table corresponding to the halftone image is selected and used to perform the density correction. Also when the kind of image is judged to be a solid image (without a portion of the halftone image), a proper table is selected similarly and used to perform the density correction.
