Liquid ejection apparatus and control method for liquid ejection apparatus

A control method for a liquid ejection apparatus which includes:

• a liquid ejection head which has nozzles configured to eject droplets of liquid toward a recording medium;
• a movement device which is configured to cause relative movement of the liquid ejection head and the recording medium;
• an elevator device which is configured to change a distance between the liquid ejection head and the recording medium;
• and a recording device which is configured to carry out recording onto the recording medium by driving the liquid ejection head to eject and deposit the droplets of the liquid onto the recording medium from the nozzles while driving the movement device to cause the relative movement of the liquid ejection head and the recording medium, the method comprising:
• an evaluation acquisition step of acquiring droplet deposition performance of the liquid ejection head evaluated in accordance with results of the recording carried out on the recording medium;
• and
• a setting step of setting the distance to as large a value as possible while satisfying droplet deposition performance required for the liquid ejection head, in accordance with the acquired droplet deposition performance.
