Recording device and recording method

A recording device, comprising:

• a transport unit configured to transport a target recording medium;
• a corona irradiation unit disposed in a transport path of the target recording medium and configured to modify a surface of the target recording medium by irradiating the surface with corona discharge;
• an ejecting unit disposed downstream of the corona irradiation unit in the transport path and configured to eject ink onto the target recording medium;
• and
• a control unit configured to control driving of the transport unit, the corona irradiation unit, and the ejecting unit, wherein
• the ejecting unit includes a first head and a second head, the first head ejecting, as the ink, a white ink for forming a background image, the second head being disposed downstream of the first head in the transport path and ejecting a colored ink for forming a colored image, and
• when the target recording medium is a registered target recording medium registered in advance, and no data for forming the background image with the white ink is included in recorded data, the control unit automatically adds, to the recorded data, the data for forming the background image with the white ink, and
• when the target recording medium is a registered target recording medium registered in advance, and no data for forming the background image with the white ink is included in the recorded data, the control unit changes intensity of the irradiation, performed by the corona irradiation unit, according to ejection density of the white ink when automatically adding, to the recorded data, the data for forming the background image with the white ink.

A recording method performed using a recording device, the recording device including

• a transport unit configured to transport a target recording medium,
• a corona irradiation unit disposed in a transport path of the target recording medium and configured to modify a surface of the target recording medium by irradiating the surface with corona discharge, and
• an ejecting unit disposed downstream of the corona irradiation unit in the transport path and configured to eject ink onto the target recording medium,
• the ejecting unit including a first head and a second head, the first head ejecting, as the ink, a white ink for forming a background image, the second head being disposed downstream of the first head in the transport path and ejecting a colored ink for forming a colored image, the recording method comprising:
• changing intensity of the irradiation, performed by the corona irradiation unit, according to presence of the background image and an ejection density of the white ink in the background image.
