摘要： In an inkjet printing apparatus which performs printing on a printing medium using an inkjet printhead for discharging ink, preliminary discharge, where ink discharge irrespective of printing is performed at the time of print execution, is performed under a predetermined condition. The printing apparatus includes a control section and a setting section. The control section executes a preliminary discharge by the printhead, which has a plurality of discharge orifices, before a predetermined time has elapsed since a latest preliminary discharge, in printing of an image, and the setting section sets the predetermined time. The setting section obtains an elapsed time after executing the preliminary discharge until a discharge failure occurs in any one of the plurality of discharge orifices, and sets the elapsed time as the predetermined time.

摘要： The image quality deterioration due to the collection of dots of low-lightness by the preliminary ejection is prevented, in the case of performing the ink ejection for preliminary ejection during the printing onto printing paper. More specifically, the preliminary ejection pattern is set as a pattern in which the distance between a cyan dot of relatively low-lightness and a magenta dot is longer than a distance between a yellow dot of relatively high-lightness and a cyan dot nearest the yellow dot among low-lightness colors. Closely forming dots of low-lightness that would be perceived as a group of collected dots can be prevented, thereby performing printing that will not deteriorate the printing quality due to the paper preliminary ejection.

摘要： In a data creating method for creating image data corresponding to each of a plurality of color inks applied to a black image area formed on the basis of image data on a black ink, with the plurality of color inks being a cyan ink, a magenta ink, and a yellow ink, an image data creating step creates image data corresponding to each of the plurality of color inks on the basis of the image data on the black ink. The image data creating step creates the image data on each of the plurality of color inks so that the rate of areas in which all the plurality of color inks are applied, in the black image area, is higher than that of areas to which only some of the plurality of color inks are applied. At least one of the cyan ink, the magenta ink, and the yellow ink contains a component that coagulates a color material of the black ink.

摘要： In an ink jet printer in which preliminary ejection is performed onto printing paper, unnecessary ink consumption due to the preliminary ejection is suppressed. More specifically, the paper preliminary ejection is designed to be performed only for a printing head of cyan ink. For this cyan ink the longest duration of its non-ejection state, in which the printer can attain high printing quality when restarting printing after continuation of the non-ejection state in the case of not performing the paper preliminary ejection, is shorter than 1.6 seconds of the duration which is necessary for the reciprocal printing. This eliminates the paper preliminary ejection for the printing heads of the other colors of ink, thereby avoiding unnecessary ink consumption due to the paper preliminary ejection performed uniformly for every color of ink.
