Abstract: An image printing apparatus and a method of controlling the same are capable of appropriately correcting the conveyance amount in each of a plurality of conveyance paths. In a case of conveying a print medium along a first conveyance path, a controller controls the driving of a conveyance motor based on first information. In a case of conveying the print medium along a second conveyance path, the controller controls the driving of the conveyance motor based on second information, which is different from the first information.

Abstract: A plurality of test patterns are printed with different print conditions, the test patterns each being formed by two inks out of a plurality of inks and a reaction liquid and including a plurality of patterns among which ejection positions of the reaction liquid relative to ejection positions of the two inks are displaced by a predetermined amount at a time. The optical properties of the respective test patterns printed on the print medium are detected. A displacement amount of the relative ejection positions of the reaction liquid from the ejection positions of the plurality of inks is obtained based on the optical property of the test pattern in which an optical density difference between the patterns in the test pattern is greater than a predetermined value and which has an optical density of a lowest level among the optical properties of the test patterns detected.

Abstract: A print position adjustment mode is performed with high accuracy while consumption of print media is saved. An inkjet printing apparatus prints an adjustment pattern including multiple patches for adjusting print positions of dots by a print head on a print medium. Patches set next to each other in a scanning direction are printed above platen ribs at intervals based on rib pitches at which the platen ribs are arranged.

Abstract: An ink jet printing apparatus and an image processing apparatus capable of stably outputting an image with no joint streak even in the case where printing conditions, such as the kind of ink and the kind of printing medium, change in a variety of ways are provided. For this purpose, correction processing is performed on image data corresponding to an eject port group located at one end part of an eject port column in a first printing scan and on image data corresponding to an eject port group located at the other end part in a second printing scan. At this time, the number of eject ports included in a first eject port group and the number of eject ports included in a second eject port group are adjusted in accordance with printing conditions.

Abstract: A technique capable of obtaining the displacement amount of the ejection position of a reaction liquid without changing a test pattern according to the configuration of the ejection head is to be provided. A test pattern including a detection pattern, which extends in a predetermined direction and in which, if divided into two, at least two inks and the reaction liquid are ejected to one area and only the at least two inks or the at least two inks and the reaction liquid of an amount that is smaller than that of the reaction liquid ejected to the one area are ejected to the other area, is printed, and the optical characteristics of the printed detection pattern are obtained. Further, based on the obtained optical characteristics of the detection pattern, the displacement amount of the ejection position of the reaction liquid in the predetermined direction is obtained.

Abstract: A printing apparatus includes a conveyance unit, a printing unit, and a heating unit that heats a print medium. The conveyance unit conveys the print medium such that the printing unit can print an image onto a second print region at a printing position when the heating unit can heat a first print region at a heating position. If the ink amount applied to the first print region is a first amount, an image is printed onto the second print region in a first mode. If the applied ink amount is a second amount larger than the first amount, an image is printed onto the second print region in a second mode. A time for which the first print region passes through the heating position in the second mode is longer than a time for which the first print region passes through the heating position in the first mode.
