Method of producing a surface appearance and paintability is excellent in melt-Al-Zn system coated steel sheet is disclosed. One side of the surface appearance and paintability method of producing a superior molten Al-Zn-based plated steel sheet of the present invention is by weight%, zinc (Zn): 35 ~ 55%, silicon (Si): 0.5 ~ 3.0%, the balance aluminum step of preparing the Al-Zn-based plating bath containing (Al) and unavoidable impurities; Step for preparing the Al-Zn, and dipping the steel sheet based on the possession of the plating bath, the plating subjected to molten Al-Zn-based plated steel sheet; And a step for cooling the molten Al-Zn-based plated steel sheet, wherein upon cooling, the molten Al-Zn aluminum powder of particle size of 18 ~ 32㎛-based coated steel sheet to the surface of
40 ~ 80g / m 2 / min and it characterized in that the injection rate.
