상기한 바와 같이 휴대단말기용 컬러 케이스윈도우 제조방법에 있어서, 윈도우원단(10)에 컬러UV패턴층(22)을 형성하는 컬러UV몰딩과정(100)과 윈도우원단(10)의 컬러UV패턴층(22)의 상면에 멀티증착층(30)을 형성하는 윈도우멀티증착과정(200), 상기 멀티증착층(30)에 블랙인쇄를 통하여 차광층(40)을 형성하는 인쇄과정(300), 컬러UV패턴층(22)과 차광층(40) 표면의 오염원을 알카리 세정하는 세정과정(400), 상기 멀티증착층과 컬러UV패턴층(22)에 보호필름(50)을 라미하여 보호하는 보호필름라미과정(500), 윈도우원단(10)을 레이저(61)에 의하여 셀단위로 커팅하는 레이저커팅과정(600)으로 이루어진 본 발명을 적용하여 실시하게 되면, 색상의 표현이 명확하게 이루어지고 생산성과 생산원가가 절감되는 것이다.In the method of manufacturing a color case window for a portable terminal as described above, a color UV molding process 100 for forming a color UV pattern layer 22 on a window fabric 10 and a color UV pattern layer A printing process 300 for forming a light shielding layer 40 through black printing on the multi-deposition layer 30, a printing process 300 for forming a light blocking layer 40 on the multi-deposition layer 30, A cleaning process 400 for cleaning the contamination source of the pattern layer 22 and the surface of the light shielding layer 40 by alkali, a protection film 50 for protecting the multi-deposition layer and the color UV pattern layer 22 by laminating the protective film 50, A laser cutting process 600 for cutting a window fabric 10 by a laser 61 in a process 500 may be performed according to an embodiment of the present invention. The cost is reduced.

한편, 본 발명은 컬러UV몰딩과정(100)에 UV레진의 조성을 전체 UV레진의 컬러UV레진을 전체 중량대비 15~25중량%로 배합조성하여 실시하게 되면, 도 9에 도시된 바와 같이 반사율편차가 낮고 증착산포가 최소화되는 것이다.In the meantime, when the color UV molding process 100 is performed by blending the composition of the UV resin with the color UV resin of the entire UV resin in an amount of 15 to 25% by weight based on the total weight, And deposition dispersion is minimized.

즉, UV레진의 조성에 있어 UV렌지의 조성이 투명레진 100% 대비 컬러UV레진 원액 투입 중량비가 10중량%일 경우 멀티증착 반사율이 투명레진 수준에 가까워 색상편차 감소가 적음을 알 수 있고, 컬러UV레진 원액 투입 중량비가 30중량%일 경우 멀티증착 반사율이 과도하게 감소되어 색상이 어둡고, UV 패턴감 구현되지 않는 문제점이 있는 것에 반하여,That is, in the composition of the UV resin, when the composition ratio of the UV range is 100% of the transparent resin and the weight ratio of the color UV resin raw material is 10% by weight, the reflectance of the multi-layer deposition is close to that of the transparent resin, When the weight ratio of the UV resin to the raw solution is 30 wt%, the multi-vapor deposition reflectance is excessively reduced, so that the color is dark and the UV pattern feeling is not realized. On the other hand,

본원 발명의 실시에 와 같이 컬러UV레진 원액 투입 중량비가 20중량%일 경우 멀티증착 반사율이 적정하게 감소되어 UV패턴감의 구현이 명확하게 이루어지고 과도한 증착 반사율로 인한 제품간 색상편차와 밝기 편차로 인한 불량이 방지되는 효과를 갖는 것을 알 수 있는 것이다.As in the practice of the present invention, when the weight ratio of the color UV resin raw stock solution is 20 wt%, the multi-layer deposition reflectance is appropriately reduced to realize the UV pattern feeling clearly and the color deviation and brightness deviation between the products due to excessive deposition reflectance It is possible to prevent defects caused by the defects.

또한, 증착 산포의 영향이 대폭 감소되어 색상 매칭이 용이하고, 양산시 멀티증착 손실이 최소화되고 색상 불량이 방지되는 것이다.In addition, the influence of deposition scattering is greatly reduced, so that color matching is easy, and the multi-deposition loss is minimized in the mass production and color defect is prevented.
