PROBLEM TO BE SOLVED: To provide a droplet jet apparatus capable of reducing the size of data for specifying a predetermined discharge pattern to be formed on a substrate. SOLUTION: A discharge initiation position Sk-n at which discharge of spacer droplets is initiated on a substrate W and a repetition rule for the spacer droplets discharged are predetermined by using a discharge droplet interval Ln between spacer droplets in the substrate-carrying direction and a discharge number Pn of the spacer droplets discharged. A comparison value m based on the distance between the discharge initiation position Sk-n and a corresponding nozzle 50 is compared with a count number of timing signals output for each predetermined moving distance with carrying of the substrate W. When the parameters are agreed with one another, discharge of spacer droplets from the nozzle 50 is initiated, and the spacer droplets are discharged at the discharge droplet intervals Ln until the discharge number reaches Pn. Since retention of only a group of parameters consisting of the discharge initiation position Sk-n, the discharge droplet interval Ln and the discharge number Pn are required to specify a discharge pattern, the apparatus can reduce the size of data for specifying a discharge pattern.
