Abstract: An image processing apparatus according to the present disclosure includes an input unit configured to input image data and a color conversion unit configured to, based on a time-dependent color variation characteristic of a printed image in a first recording medium, perform color conversion on the image data corresponding to time-dependent color variation of a second recording medium.

Abstract: A printing method capable of appropriately drying a printing medium is provided. The printing method includes an ink application step and a drying step of drying a printing medium to which ink has been applied at the ink application step. In a case where a printing medium is a first type, at the drying step, the printing medium is dried by using a first drying method so that the water content of the printing medium is included within a predetermined range. In a case where a printing medium is a second type whose tendency to contain water is stronger than that of the first type, at the drying step, the printing medium is dried by using a second drying method whose drying effect is higher than that of the first drying method so that the water content of the printing medium is included within the predetermined range.

Abstract: A method to clean a discharge port surface of a recording apparatus includes applying a cleaning liquid to the discharge port surface by a cleaning liquid application unit. The discharge port surface includes a discharge port line, a hydrophilic part, and a water-repellent part located between the hydrophilic part and the discharge port line. A plurality of discharge ports to discharge a liquid is aligned in a first direction. The hydrophilic part is provided separated from the discharge port line and protrudes from the discharge port surface in a discharge direction of the liquid from the plurality of discharge ports. After the cleaning liquid is applied to the discharge port surface, a cleaning liquid removal unit removes the applied cleaning liquid in a state where the cleaning liquid has been moved onto the hydrophilic part.
