    Abstract: The present invention relates to a system (1) for applying at least two kinds of liquid onto respective targeted areas of a substrate (S). The system (1) includes first and second storage unit (10a, 10b) that accommodate first and second liquids (F1, F2); a pressured gas supply unit (20) that is fluidly connected to the first and second storage unit (10a, 10b); first and second applicator (30a, 30b) that are fluidly connected to the first and second storage unit (10a, 10b); and a controller (40) that is operatively connected to the applicator (30a, 30b). The pressured gas supply unit (20) causes pressure of a pressured gas to act on the liquids (F1, F2) within the storage unit (10a, 10b). The first and second applicator (30a, 30b) each include at least one nozzle (300a, 300b) disposed so as to face the substrate (S). The first and second applicator (30a, 30b) spray the first and second liquids (F1, F2) within the first and second storage unit (10a, 10b) from the nozzles (300a, 300b) toward the substrate (S) by the action of the pressured gas from the pressured gas supply unit (20). The controller (40) individually controls the first and second applicator (30a, 30b) so that the first applicator (30a) sprays the first liquid (F1) toward a targeted area for the first liquid (F1) on the substrate (S) and the second applicator (30b) sprays the second liquid (F2) toward a targeted area for the second liquid (F2) on the substrate (S). The present invention also relates to a method for applying at least two kinds of liquid onto respective targeted areas of a substrate (S).
