Description

에칭용 UV잉크와 하이브리드판을 배제하는 UV에칭코팅 방법{UV ETCH COATING METHOD WITHOUT UV INK FOR ETCHING AND HYBRID PLATE}UV etching coating method that excludes etching UV ink and hybrid plate {UV ETCH COATING METHOD WITHOUT UV INK FOR ETCHING AND HYBRID PLATE}

본 발명은 에칭용 UV잉크와 하이브리드판을 배제하는 UV에칭코팅 방법에 관한 발명으로, 더욱 상세하게는 UV옵셋인쇄기를 이용한 하이브리드 인쇄에서, 별도의 UV잉크 및 하이브리드판의 사용을 배제하고 일반잉크를 이용하여 인쇄물에 UV에칭 및 UV코팅 효과를 발현하도록 이루어지는 UV에칭코팅 방법에 관한 것이다.The present invention relates to a UV etching coating method that excludes the etching UV ink and the hybrid plate, and more particularly, in hybrid printing using a UV offset printer, the use of a separate UV ink and a hybrid plate is excluded, and general ink is eliminated. It relates to a UV etching coating method made to express UV etching and UV coating effects on printed materials by using.

일반적으로, 옵셋인쇄는 평판 인쇄법의 일종으로 인쇄용 판재에 잉크를 칠하여 고무 롤러에 전사한 다음 종이에 전사하는 방식의 간접 인쇄법이다.In general, offset printing is an indirect printing method in which ink is painted on a printing plate, transferred to a rubber roller, and then transferred to paper.

옵셋인쇄는 인쇄판에 종이가 직접 닫는 직접 인쇄법과는 달리 거친 종이에도 우수한 인쇄품질을 도출할 수 있으며 다수의 상이한 각도로 타공된 인쇄용 판재를 이용해 다색 컬러인쇄가 가능하므로 고해상도가 요구되는 각종 신문, 잡지 및 각종 홍보물, 명함 등 다양한 인쇄물의 인쇄에 널리 이용된다.Offset printing can derive excellent print quality even on rough paper, unlike the direct printing method in which the paper is directly closed on the printing plate, and multi-color printing is possible using printing plates perforated at a number of different angles, so various newspapers and magazines that require high resolution And it is widely used for printing various printed materials such as various promotional materials and business cards.

옵셋인쇄에 사용되는 인쇄용 판재는 판면이 평활한 금속 판재가 사용되며 판재의 표면에는 감광물질이 처리되어 있어 화선부는 친유성을 띄고 비화선부는 친수성을 띄게 된다. 따라서, 물과 기름이 반발하는 성질을 이용하여 판면에 물을 칠하면서 유성의 잉크를 묻히면 비화선부에는 물이 있어 잉크가 묻지 않고 물이 없는 화선부에만 잉크가 묻는 원리로 인쇄가 이루어진다.As for the printing plate used for offset printing, a metal plate with a smooth plate surface is used, and a photosensitive material is treated on the surface of the plate, so that the caustics have lipophilicity and the non-flowering portions have hydrophilicity. Therefore, using the property of repelling water and oil, if oily ink is applied while painting water on the surface of the plate, printing is performed on the principle that the non-caustic line part has water, so that ink does not adhere, and ink only adheres to the caustic part without water.

상기한 바와 같은 옵셋인쇄에 사용되는 잉크는 유기 용제형이 대부분이므로 인체에 유해한 성분을 함유하는 휘발성 유기용제의 사용이 불가피하여 최근에는 자외선 경화능을 가진 UV잉크를 사용하는 UV옵셋인쇄가 보편화되는 추세이다.Since most of the inks used for offset printing as described above are of organic solvent type, the use of volatile organic solvents containing harmful components to the human body is inevitable. It is a trend.

즉, UV옵셋인쇄에 사용되는 UV잉크는 자외선(UV)에 노광 시 순간적으로 경화되는 특성을 가지므로 종래 유기 용제형 잉크에 비해 경화, 건조능이 우수하여 작업성 및 생산성이 높고 무공해에 가까운 등의 이점이 있다. In other words, because UV ink used for UV offset printing has the property of instantaneous curing when exposed to ultraviolet rays (UV), it has excellent curing and drying ability compared to conventional organic solvent-type inks, resulting in high workability and productivity, and close to pollution-free. There is an advantage.

한편, 최근에는 고급명함이나 화장품 패키지 등 인쇄 부위에 엠보싱 질감을 부여하여 고급스러운 느낌을 표출하도록 하는 에칭 효과에 대한 수요가 증대되고 있다. On the other hand, in recent years, there is an increasing demand for an etching effect for expressing a luxurious feeling by giving an embossed texture to a printed area such as a luxury business card or a cosmetic package.

인쇄물에 에칭 효과를 발현하는 방법은, 종래에는 예컨대 한국공개특허 제 10 - 2003 - 0025994 호에 공지된 바와 같이 옵셋인쇄기를 구조 변경하여 잉크가 묻혀지는 판통과, 판통과 접하면서 잉크가 전이되는 블랭킷과, 블랭킷과 접하면서 인쇄용지를 이송시키는 압통을 포함하고, 블랭킷의 외주에 양면테이프를 부착해 외주에 수지판이나 후렉소판을 부착하여 블랭킷을 에칭잉크를 전달하는 인쇄판으로 사용되는 옵셋인쇄기에 의한 에칭인쇄 방법이 사용되었다.The method of expressing the etching effect on printed matter is conventionally, as known in Korean Patent Laid-Open Patent No. 10-2003-0025994, by changing the structure of an offset printer to a plate tube where ink is embedded, and a blanket in which ink is transferred while contacting the plate And, it includes a pressure cylinder that transfers printing paper while in contact with the blanket, and attaches a double-sided tape to the outer periphery of the blanket and attaches a resin plate or flexo plate to the outer periphery. An etching printing method was used.

다른 예로서, 한국공개특허 제 10 - 2005 - 0064970 호에는 UV잉크와 아크릴 레진의 비드를 혼합하는 혼합공정과, 혼합공정을 거쳐 혼합되어진 혼합액을 유리, 아크릴, 폴리카보네이트 등의 각종 판재에 실크스크린 인쇄하는 인쇄공정과, 실크스크린 인쇄 후 자외선으로 건조하는 건조공정으로 이루어지는 실크스크린 인쇄를 이용하여 에칭이 표현되도록 한 판재 제조방법을 구성한다.As another example, in Korean Patent Laid-Open No. 10-2005-0064970, a mixing process of mixing a bead of UV ink and acrylic resin, and a mixed liquid mixed through the mixing process are silkscreened on various plates such as glass, acrylic, and polycarbonate. A method of manufacturing a plate material is constructed so that etching is expressed by using a silk screen printing consisting of a printing process of printing and a drying process of drying with ultraviolet rays after silk screen printing.

한국공개특허 제 10 - 2003 - 0025994 호 (2003.03.31)Korean Patent Laid-Open Patent No. 10-2003-0025994 (2003.03.31) 한국공개특허 제 10 - 2005 - 0064970 호 (2005.06.29)Korean Patent Laid-Open Patent No. 10-2005-0064970 (2005.06.29)

종래에는 주로 실크스크린 방법을 이용해 기존 인쇄 부위에 에칭용 잉크를 인쇄하여 에칭 효과를 발현하는 방법이 사용되었으나, 인체에 유해한 유기 용제형 잉크를 사용함에 따른 문제점으로 인해, 최근에는 자외선 경화형 UV잉크를 사용하는 UV옵셋인쇄가 널리 이용되고 있다.Conventionally, a method of expressing an etching effect by printing an etching ink on an existing printing area using a silk screen method was mainly used, but due to the problem of using an organic solvent type ink that is harmful to the human body, recently, ultraviolet curable UV ink UV offset printing used is widely used.

일반적으로, UV옵셋인쇄기를 이용하여 인쇄물에 에칭 효과를 발현하는 방법은 4원색 UV잉크를 인쇄하는 단계와, 에칭용 UV잉크와 바니쉬를 하이브리드판으로 인쇄하는 단계를 거친 후, UV램프로 건조하는 방식으로 이루어진다.In general, the method of expressing the etching effect on prints using a UV offset printer is to print four primary color UV inks, print the etching UV inks and varnishes on a hybrid plate, and then dry them with a UV lamp. Done in a way.

그러나, 종래의 UV에칭에 사용되는 에칭용 UV잉크 및 하이브리드판은 비용이 고가이므로 원가 상승이 야기됨은 물론, 공정 소요시간이 장시간 소요되므로 생산성을 저하시키는 문제점이 있다.However, the conventional UV inks and hybrid plates for etching used in UV etching have a problem of lowering productivity because the cost is high and thus the cost increases, as well as the processing time required for a long time.

상기 바니쉬층형성단계(S20)를 거쳐 4원색 일반잉크층 및 바니쉬층(104)이 형성된 인쇄물(101)에 UV램프를 조사하여 UV코팅(105) 및 UV에칭(106) 반응을 촉발하는 자외선반응단계(S30)를 포함하여 구성함으로써 별도의 UV잉크 및 하이브리드판의 사용을 배제하고 일반잉크를 이용하여 인쇄물에 UV에칭 및 UV코팅 효과를 발현할 수 있는 목적 달성이 가능하다.UV reaction to trigger the UV coating 105 and UV etching 106 reaction by irradiating a UV lamp on the printed material 101 on which the four primary color general ink layers and the varnish layer 104 are formed through the varnish layer forming step (S20) By including the step (S30), the use of separate UV ink and hybrid plate is eliminated, and the purpose of expressing UV etching and UV coating effects on printed materials using general ink can be achieved.

본 발명은 UV옵셋인쇄기를 이용한 하이브리드 인쇄에서 에칭 효과를 발현하기 위해 종래에 UV잉크 및 하이브리드판을 사용하는 공정을 배제하는 UV에칭코팅 방법을 제공한다.The present invention provides a UV etching coating method that excludes the conventional process of using a UV ink and a hybrid plate to express an etching effect in hybrid printing using a UV offset printer.
