Printing device and control method of printing device

A printing device comprising:

• a transport device that transports a long substrate along a transport path and that winds the substrate with a winding device;
• an ink applying device that is disposed in the transport path and that applies an ink to a printing surface of the substrate;
• a pretreatment liquid applying device that is disposed on an upstream side of the ink applying device in the transport path and that applies a pretreatment liquid to the printing surface of the substrate,
• wherein the pretreatment liquid contains a resin of which a softening temperature is Ts;
• a first drying device that is disposed on a downstream side of the ink applying device in the transport path and that dries the ink applied to the printing surface of the substrate;
• and
• at least one processor,
• wherein the processor is configured to:
• stop transport of the substrate once an end part that is an end of a region of the printing surface of the substrate, to which the pretreatment liquid is applied, reaches between the first drying device and the winding device, in a case of stopping the transport of the substrate;
• set the first drying device to a first temperature in a printing mode in which the substrate is transported and set the first drying device to a third temperature in a printing standby mode in which the transport of the substrate is stopped, and
• the Ts satisfies a relationship of the first temperature>the Ts>the third temperature.

A control method of a printing device including a transport device that transports a long substrate along a transport path and that winds the substrate with a winding device, an ink applying device that is disposed in the transport path and that applies an ink to a printing surface of the substrate, a pretreatment liquid applying device that is disposed on an upstream side of the ink applying device in the transport path and that applies a pretreatment liquid to the printing surface of the substrate, and a first drying device that is disposed on a downstream side of the ink applying device in the transport path, that has a pass roller coming into contact with the printing surface of the substrate, and that dries the ink applied to the printing surface of the substrate, a second drying device that is disposed on the downstream side of the first drying device in the transport path, the control method comprising:

• stopping transport of the substrate once an end part that is an end of a region of the printing surface of the substrate, to which the pretreatment liquid is applied, reaches between the first drying device and the winding device, in a case of stopping the transport of the substrate,
• setting the first drying device to a first temperature and set the second drying device to a second temperature lower than the first temperature,
• wherein the pretreatment liquid contains a resin of which a softening temperature is Ts, and
• the Ts satisfies a relationship of the first temperature>the Ts>the second temperature.
