    摘要: Provided are an ink jet printing apparatus and an ink jet printing method which are capable of printing high-quality images by performing printing scanning in a forward direction and in an opposite direction without needing complicated control of a transfer amount of a printing medium nor causing throughput degradation. Inks are ejected from odd-numbered nozzles in scanning in the forward direction and are ejected from even-numbered nozzles in scanning in the opposite direction.

    摘要: When completing an image in a predetermined area by an odd or even number of bidirectional printing scans, this invention makes it possible to suppress lines of image defects and density variations and thereby print a high-quality image at high speed. In completing an image by an odd number of bidirectional printing scans, the print data for small ink droplets and large ink droplets are thinned using the first and second thinning pattern. The first and second thinning pattern thin the print data for small ink droplets and large ink droplets so that a difference between the total print ratio of all forward printing scans of the odd number of scans and the total print ratio of all backward printing scans of the odd number of scans when the first thinning pattern is used differs from that when the second thinning pattern is used.

    摘要: In an image printing apparatus for printing an image by combining dots of a plurality of sizes, a banding problem attributable to variations in conveying operation, and a temperature rise of a print head with an increase of the number of ejections are solved with a relatively simple configuration. To this end, a combination of dots of a plurality of sizes is assigned to each of pixels expressed at a plurality level of density. In this assignment, a dot larger than a pitch of an image resolution is preferentially allocated to a pixel having a density level higher than that to which one dot smaller than the pitch of the image resolution is allocated.

    摘要: When the head temperature Tfinish, which is the head temperature at the time of completion of a preceding scan, is higher than the stable ejection temperature Tstable, the target temperature is made a temperature that is only a temperature value ΔT lower than the head temperature Tfinish. On the other hand, when Tfinish, the head temperature at the time of print completion, is lower than the stable ejection temperature Tstable, the target temperature is made a temperature that is only a temperature value ΔT higher than the head temperature Tfinish. Because of this it is possible to inhibit head temperature rise in the case where an image with a high print density is printed.

    摘要: An inkjet printing apparatus of the present invention is equipped with a recovery device for recovering an ink ejection state of a print head. The print head has a plurality of nozzle rows each for ejecting an ink of a different color, and a nozzle surface. The recovery device performs wiping of the nozzle surface and preliminary ejection from the print head. After the wiping, an evaluation patch is created by performing the preliminary ejection onto a printing medium, and the number of preliminary ejections of a specific nozzle is increased to a number larger the number of preliminary ejections of other nozzles based on an image of the evaluation patch. It is possible to appropriately decide the number of preliminary ejections for each nozzle according to color mixture parts that vary for every apparatus.

    摘要: An ink jet printing apparatus performs printing on a print medium, and includes a print head having a plurality of ejection openings, a head temperature acquisition unit that acquires a temperature of the print head, and a heating unit configured to heat the print head. In addition, a control unit is configured to control the heating unit so as to cause a temperature of the print head to be a target temperature, at start of a print scan by the print head, and a setting unit is configured to set the target temperature. If a completion temperature acquired by the acquisition unit at a time when a previous print scan is completed is lower than a threshold temperature, the setting unit sets a temperature higher than the completion temperature as the target temperature, and if the completion temperature is equal to or higher than the threshold temperature, the setting unit sets a temperature lower than the completion temperature as the target temperature.
