A method of manufacturing a glossy door side step using a masking film according to the present invention includes the following processes. The method of manufacturing a glossy door side step using a masking film comprises: a masking step of attaching a masking film (F) having an opening (F1) in the shape of a pattern (L) to an upper surface of a material plate (M); a polishing step of polishing, after the masking step (S2), an upper surface of the masking film (F) so that a part of the material plate (M), exposed through the opening (F1), is also polished; a peeling step (S4) of peeling off, after the polishing step, the masking film (F); an embossing step of protruding, after the peeling step (S4), the polished part of the material plate (M) upward. Therefore, the following effects can be obtained. The pattern (L) of a door side step (S) protrudes upward and is glossy to distinguish the same from a background (B), thereby improving three-dimensional visibility and creating an external aesthetic sensibility. In addition, as in the background technology, the background (B) is etched and made thin, so that the pattern (L) does not protrude. However, the pattern (L) protrudes by a press (1), so a door side step (S) with improved strength compared to background technology can be manufactured. Therefore, the quality of the door side step (S) can be improved compared to the background technology.

    본 발명에 의한 '마스킹 막을 이용한 광택 도어사이드스텝의 제조방법'은 다음 공정으로 이루어진다. 소재판(M)의 상면에, 문양(L) 형상의 개방부(F1)가 형성된 마스킹 막(F)을 부착시키는 마스킹 단계와, 상기 마스킹 단계(S2) 이후에, 상기 마스킹 막(F)의 상면을 폴리싱하므로 상기 개방부(F1)를 통해 노출된 상기 소재판(M)의 부분도 폴리싱되게 하는 폴리싱 단계와, 상기 폴리싱 단계 이후에, 상기 마스킹 막(F)을 벗겨내는 박리단계(S4)와, 상기 박리단계(S4) 이후에, 상기 소재판(M)에서 폴리싱된 부분을 상방으로 돌출시키는 엠보싱 단계를 포함한다. 따라서, 다음과 같은 효과를 얻을 수 있다. 도어사이드스텝(S)의 문양(L)이 상방으로 돌출되고 배경(B)과 구별되도록 광택이 발현되도록 하므로 입체적으로 시인성이 향상되고 외적으로 심미감을 연출할 수 있다. 또한, 배경기술처럼 상기 배경(B)을 식각시켜 얇게 하므로 문양(L)을 돌출시키지 않고 프레스(1)에 의해서 문양(L)이 돌출되도록 하므로 배경기술에 비해서 강도가 향상된 도어사이드스텝(S)을 제조할 수 있다. 따라서, 배경기술에 비해서 도어사이드스텝(S)의 퀄리티를 향상시킬 수 있다.
