Print data is organized over rows and columns. The columns of each row are selectively assigned to calibration tables respectively corresponding to printheads of a pagewide array in accordance with a substrate advancement skew relative to the pagewide array. The calibration tables are applied to the columns of each row respectively assigned to the calibration tables. The columns of each row to which the calibration tables have been applied are printed using the printheads respectively corresponding to the calibration tables.

Technology for inspection for detecting a defect of a printed matter using machine logic informed by machine learning. Some embodiments of the present invention may include one, or more, of the following features: (i) generates defect datasets; (ii) generates defect libraries; (iii) uses the generated defect libraries for deep learning training; and (iv) uses machine learning to detect defects using computer code (for example, a *.jpg format file) corresponding to an image of a piece of printed matter instead of using a visual image (that is, an image of the type that is created when a person takes a picture using a traditional film camera).

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.

A printer includes an ink head including a nozzle, a damper connected with the ink head, a pressure sensor to detect a damper pressure in the damper, a cap attachable to the ink head so as to cover the nozzle, an upward/downward moving mechanism to move the cap upward and downward with respect to the ink head, a suction pump connected with the cap, and a controller. The controller is configured or programmed to include a suction controller to execute a suction process to drive the suction pump in a state where the cap is attached to the ink head, a pressure acquisition controller to acquire the damper pressure from the pressure sensor during the suction process, and an upward/downward movement controller to control the cap to move upward toward the ink head when a change amount of the damper pressure is no larger than a reference change amount.
