Abstract: A substrate processing condition setting method includes acquiring, causing, and setting. In the acquiring, a plurality of estimation processing results are acquired by inputting a plurality of processing conditions to a trained model that is subjected to machine training based on a training processing condition and a processing result obtained by processing a substrate under the training processing condition. In the causing, a display section is caused to display an image based on the estimation processing results. In the setting, one processing condition corresponding to one estimation processing result of the estimation processing results is set, as an actual processing condition in substrate processing, based on the image displayed on the display section.

Abstract: A mist collecting unit for collecting a mist of ink droplets. The mist collecting unit includes the following elements. An introduction pipe, a mist introducing box with the introduction pipe mounted to have an upper part open, and a collecting box attached to a lower part of the mist introducing box. The gas is introduced from the introduction pipe into the collecting box, thereby capturing the mist included in the gas by inner surfaces of the collecting box.
