Printing device and printing method

A printing device comprising:

• an ink container accommodating a liquid, the liquid comprising a clear ink comprising water and a resin;
• a discharging head configured to discharge the clear ink directly or indirectly onto a substrate to form a printing layer;
• and
• a heating device configured to heat the substrate,
• wherein the following relationship is satisfied:
• HTlow (degrees C.)>HThigh (degrees C.), where HTlow (degrees C.) represents a temperature of the heating device during printing in a low gloss printing mode to impart low gloss to the printing layer and HThigh (degrees C.) represents a temperature of the heating device in a high gloss during printing in a high gloss printing to impart high gloss to the printing layer,
• wherein the following relationships are satisfied:
• in the high gloss printing mode, Gp≥Gm and, in the low gloss printing mode, Gm≥Gp, where Gm represents a gloss level of the substrate and Gp represents a gloss level of the printing layer.

• heating the substrate by a heating device,
• wherein the following relationship is satisfied:
• HTlow (degrees C.)>HThigh (degrees C.), where HTlow (degrees C.) represents a temperature of the heating device during printing in a low gloss printing mode to impart low gloss to the printing layer and HThigh (degrees C.) represents a temperature of the substrate that the heating device is heating during printing in a high gloss printing mode to impart high gloss to the printing layer,
• wherein the following relationship is satisfied:
• in the high gloss printing mode, Gp≥Gm and, in the low gloss printing mode, Gm≥Gp, where Gm represents a gloss level of the substrate and Gp represents a gloss level of the printing layer.
