The present invention relates to a half-tone dot gradation type transfer printing film, to a method for manufacturing a mold and to a mold manufactured thereby. Traditional multiple etching treatment, which is complex and complicated, is made simple and efficient by applying the technique of expressing shade and contours using minute half-tone dots in the field of printing techniques to the field of etching techniques. Accordingly, process efficiency can be enhanced, economical efficiency can be improved via a reduction in costs, and a defect generation rate can be reduced significantly by reducing multiple etching recovery effectively and efficiently. |
