Abstract: At step S115, a printer control unit refers to a table using an average print duty as an input, and determines a saturation temperature and a drum preliminary heating temperature. In this example, since the saturation temperature and the preliminary heating temperature with respect to the print duty are stored as a table, the printer control unit refers to the table using the average print duty as the input, and determines the saturation temperature and the drum preliminary heating temperature. At step S120, the printer control unit investigates a current drum temperature based on a measurement result of a temperature sensor. Subsequently, at step S125, the drum is heated or cooled until it reaches, of the saturation temperature and the drum preliminary heating temperature, the temperature for which the difference with the current drum temperature is smaller.

Abstract: A recording device includes a head including a first nozzle row that discharges a plurality of drawing inks; and a second nozzle row that discharges an overcoat ink posterior to the drawing inks, and also includes a dot-data generating unit that performs dot-data generating processing including halftone processing using a dither mask. When generating dot data used to perform recording in accordance with a first recording mode in which no nozzle that discharges the overcoat ink is assigned to part of pixels in a recording target region of the recording medium, the first recording mode being a recording mode using the second nozzle row, the dot-data generating unit generates the dot data by using a first overcoat dither mask having a threshold value set so as not to form a dot with the overcoat ink on the part of pixels.
