Abstract: A printing apparatus includes: a gloss forming unit that forms at least two regions having different gloss levels on a print medium; and a print image forming unit that forms a print image on the at least two regions having different gloss levels of the print medium after the gloss forming unit forms the at least two regions.

Abstract: An ink jet printing apparatus includes: a conveying mechanism that moves at least one of a print medium and an ink jet head in a predetermined conveyance direction; a height information detecting unit that obtains information related to the height of the surface of the print medium; a moving mechanism that moves at least one of the ink jet head and the print medium upward and downward in the vertical direction; and a control unit that controls the ink jet head while sequentially controlling the moving mechanism accompanying conveyance by the conveying mechanism, based on the information related to the height which is detected by the height information detecting unit, thereby maintaining the distance between the print medium and the ink jet head to be within a range which is set in advance, to perform a printing process on the print medium.

Abstract: A controller determines the amount of driving by a sub-scanning driver and the number of nozzles to be used in accordance with a maximum amplitude of vibration of an inkjet head in a sub-scanning direction, where the maximum amplitude is detected by a displacement detecting sensor when the inkjet head is moved in the sub-scanning direction before starting printing. Then, while moving the inkjet head in a main-scanning direction, the controller performs printing by selecting nozzles to be used in accordance with displacement of the inkjet head in the sub-scanning direction detected by the displacement detecting sensor.

Abstract: The inkjet printing machine includes a controlling unit, an inkjet head including a plurality of nozzles, and a head elevating motor that causes the inkjet head to move up or down. The controlling unit causes, while the inkjet head is being moved in a main-scanning direction, the head elevating motor to move the inkjet head up or down depending on unevenness of a surface of a printing medium, selects a nozzle from the nozzles depending on a distance between the inkjet head and the surface of the printing medium at a position of each of the nozzles, and performs printing by using the selected nozzle.
