Description
본 발명은 옵셋인쇄 방법으로 실크인쇄처럼 나타낼 수 있는 옵셋 인쇄방식에 의한 에칭인쇄에 관한 것이다.The present invention relates to an etching printing by an offset printing method which can be represented as silk printing by an offset printing method.
옵셋인쇄방식은 도 1에 도시된 바와 같이, 급지장치, 인쇄장치, 습수장치,잉크공급장치, 배지장치로 이루어진 인쇄기 사용하는 것으로 판면이 볼록하거나 오목한 부분은 없지만 인쇄판상에 화선부로서 잉크에 친화성이 높은 부분과 비화선부로서 잉크에 친화성이 낮은 부분을 만들어 판면에 물과 잉크를 서로 묻혀줌으로서 감지성 화선부에는 잉크가 부착하고, 비화선부는 물의 엷은 층(축임물, 습수)으로 보호되기 때문에 잉크는 부착되지 않는다. 이와 같이 물과 기름이 서로 반발한다고 하는 성질을 이용해서 인쇄하는 방법인데, 이렇게 해서 인쇄판의 화선부에 묻은 잉크를 일단 탄력성이 있는 고무를 붙인 실린더(블랭킷)에 옮기고, 도 2와 도 3에 도시된 바와 같이 다시 여기로부터 인쇄용지로 전사하는 방식이다.The offset printing method uses a printer consisting of a paper feeder, a printing device, a wet water device, an ink supply device, and a discharge device, as shown in FIG. This high part and the non-flammable part make the part with low affinity for ink, so that water and ink are buried together on the plate surface so that the ink adheres to the sensitive fraud part, and the non-flammable part is protected by a thin layer of water (condensate, damp water). No ink is attached. In this way, the water and oil repel each other and print using the properties. In this way, the ink on the wire portion of the printing plate is transferred to the elastic rubber-coated cylinder (blanket), which is illustrated in FIGS. 2 and 3. As described above, the printing paper is transferred from here to printing paper.
옵셋인쇄방식은 잉크 전달량이 적어 명확한 윤곽은 형성하지 못하나 부드러운 느낌의 인쇄물을 재현할 수 있고, 밑판부분의 잉크 부착이 좋으며, 인쇄판을 만드는 것이 다른 판식에 비하여 용이하고 안정성이 있고, 망점재현성이 양호하여 칼라 인쇄가 용이하다는 장점 때문에 현재에는 옵셋인쇄방식이 일반화 되어 있다.The offset printing method does not form a clear outline due to the small amount of ink delivery, but it can reproduce the printed material with a soft feeling, and the adhesion of ink on the bottom plate is good, making the printing plate easier and more stable than other plates, and the dot reproducibility is good. Because of the advantage of easy color printing, offset printing is now commonplace.
에칭인쇄는 인쇄면에 엠보싱을 형성하여 손으로 만져보면 오돌토돌한 느낌의 인쇄물을 얻는 것으로, 주로 양주, 의약품, 화장품의 패키지용으로 고급감을 주기 위해 금색이나 은색으로 많이 사용되고 있으며 지금까지는 실크스크린 방식으로 이루어지고 있다.Etching prints are embossed on the printed surface to obtain a print that feels as if touched by hand. It is mainly used in gold or silver to give a sense of quality for the packaging of liquor, medicine, and cosmetics. It is done.
그러나, 실크스크린 방식에 의한 에칭인쇄에서 실크에칭잉크는 과다한 잉크 사용과 그로 인한 건조지연, 기계 운전속도 저하 등으로 생산성 저하와 비용증가가 발생하며 충분한 작업시간과 작업공간을 가져야 한다.However, silk etching ink in the silkscreen etching printing has to reduce productivity and increase cost due to excessive ink use, delay in drying, and lowering of machine operation speed, and have sufficient working time and working space.
그래서 에칭인쇄로 대량생산과 원가 절감을 하기 위해서는 실크 스크린 방식이 아닌 옵셋 인쇄와 동시에 건조가 이루어지는 자동건조방식을 적용할 수 있는 옵셋인쇄방식을 이용하여야 한다. 즉 자동인쇄건조방식은 UV 에칭잉크를 사용하여 인쇄와 동시에 자외선을 비춰 순간적으로 인쇄면을 경화, 건조시켜 뒷묻음이 생기지 않게 하는 장식으로 옵셋인쇄 방식에서만 사용할 수 있다.Therefore, in order to reduce mass production and cost by etching printing, the offset printing method that can be applied to the automatic drying method that is dried at the same time as the offset printing rather than the silk screen method should be used. In other words, the automatic printing drying method can be used only in the offset printing method as a decoration that hardens and dries the printing surface by irradiating UV light at the same time using UV etching ink to prevent backing.
이러한 실크스크린 방식에 의한 에칭인쇄는 소량생산, 잉크의 과다사용과 작업시간이 길어지는 단점이 있다.Etch printing by the silk screen method has a disadvantage in that a small amount of production, excessive use of ink and a long working time.
본 발명은 전술한 바와 같은 문제점을 해결하기 위한 것으로, 인쇄 소재에 에칭잉크를 전달하는 전이소재를 개발하여 인쇄장치의 일 구성부인 블랭킷을 인쇄판으로 하는 옵셋인쇄기와 상기 옵셋인쇄기에 의한 에칭인쇄 방법을 제공함에 있다.The present invention is to solve the problems as described above, to develop a transfer material for transferring the etching ink to the printing material by using an offset printing machine and the offset printing method using a blanket as a printing plate as a component of the printing device.

이하, 첨부된 도면을 참조하여 본 발명을 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
도 5에 도시된 바와 같이, 본 발명에 따른 옵셋 인쇄기는 기존과 마찬가지로 급지장치, 인쇄장치(판통, 블랭킷, 압통), 잉크공급장치(잉크롤러), 배지장치로 구성된 인쇄기에 있어서, 인쇄장치를 구조변경하여 에칭인쇄를 가능하게 한다.As shown in FIG. 5, the offset press according to the present invention, as in the prior art, includes a paper feeder, a printing device (plate, blanket, presser), an ink supply device (ink roller), and a discharge device. The structure is changed to enable etching printing.
인쇄장치는 잉크를 이송시키는 잉크롤러에 의해 잉크가 묻혀지는 판통(12)과 상기 판통의 잉크가 전이되는 블랭킷(14)이 감겨진 블랭킷통(13)과 상기 블랭킷통(13)과 맞물려 회전하는 압통(16)으로 구성되어 있다.The printing apparatus is engaged with the blanket cylinder 13 on which the ink is buried by the ink roller for transferring ink and the blanket 14 on which the ink of the sheet is transferred, and the blanket cylinder 13 wound thereon to rotate. It consists of the impression cylinder 16.
종래 판통(12)의 외주에는 화선부와 비화선부로 구별되어 인쇄형상이 도안된 부식판(인쇄판)이 감겨져 있고 물과 기름의 반발작용으로 선택적으로 잉크가 묻혀지지만 본 발명에서의 판통은(12) 화선부와 비화선부로 구별하지 않고 모두 비화선부가 되어 전체적으로 잉크가 묻혀진다.The outer circumference of the conventional plate 12 is divided into a wire line and a non-wire line, and a corroded plate (print plate) in which the printing shape is designed is wound, and ink is selectively buried by the repulsive action of water and oil. Irrespective of the fire line and non-fire line, all of them become non-fire line and the ink is buried as a whole.
상기와 같이 판통(12)의 인쇄판에 묻혀진 잉크는 판통의 회전에 의하여 블랭킷(14)에 전이되는데, 종래의 블랭킷(14)의 구조는 외주에 고무판이 감겨져 형성되어 있으므로 고무 블랭킷이라고도 하였지만, 본 발명에서는 도 4에 도시된 바와 같이 블랭킷(14)의 구조는 외주에 고무판이 아닌 수지판(22)이나 후렉소판(22)이 감겨져 이루어진다.The ink buried in the printing plate of the plate 12 as described above is transferred to the blanket 14 by the rotation of the plate, the structure of the conventional blanket 14 is also referred to as a rubber blanket because the rubber plate is formed around the outer periphery, In FIG. 4, the structure of the blanket 14 is formed by winding a resin plate 22 or a flexo plate 22 instead of a rubber plate on an outer circumference thereof.
본 발명에 따른 블랭킷의 구조를 좀 더 자세히 설명하면 도 4에 도시된 바와 같이, 블랭킷(14)의 외주에 양면 테이프(18)를 붙이고 그 위에 수지판(22)이나 후렉소판(22)을 감아서 접착시킨다. 여기서 수지판(22)이나 후렉소판(22)에는 에칭에 의한 인쇄형상을 도안(화선부와 비화선부로 구별)시켜 종래의 판통에 감겨진 잉크가 묻혀지는 인쇄판(전이소재)의 기능이 된다.Referring to the structure of the blanket according to the present invention in more detail as shown in Figure 4, the double-sided tape 18 is attached to the outer periphery of the blanket 14, the resin plate 22 or flexo plate 22 is wound thereon Glue them together. Here, the resin plate 22 and the flexographic plate 22 design the printing shape by etching (divided into a line portion and a non-line portion) to serve as a printing plate (transition material) in which ink wrapped in a conventional plate is buried.
그리고 상기한 수지판(22)이나 후렉소판(22)은 블랭킷(14)의 외주 전체에 걸쳐서 부착할 수 있고, 필요에 따라 일부분에만 부착할 수도 있다.The resin plate 22 and the flexo plate 22 can be attached over the entire outer circumference of the blanket 14, and can be attached only to a part of the sheet as needed.
상기와 같이 부착된 수지판(22)이나 후렉소판(22)은 그 두께를 기존의 판통에 감겨지는 인쇄판의 두께 보다 두껍게 제조되어 있으므로 수지판(22)이나 후렉소판(22)에 형성되는 에칭 깊이도 깊게 할 수 있다. 따라서 수지판(22)이나 후렉소판(22)에 의해 찍힌 인쇄용지(20)들은 실크스크린 에칭인쇄와 같은 실제적인 효과가 나타난다.Since the resin plate 22 or flexo plate 22 attached as described above is manufactured to have a thickness greater than the thickness of the printing plate wound on the existing plate, the etching depth formed on the resin plate 22 or the flexo plate 22. You can also deepen. Therefore, the printing paper 20 imprinted by the resin plate 22 or the flexographic plate 22 exhibits practical effects such as silk screen etching printing.
상기와 같이 수지판(22)이나 후렉소판(22)에 의해 인쇄를 진행한 상태에서 기존과 마찬가지로 UV 자동건조방식을 사용하여 옵셋인쇄방식의 UV 에칭인쇄물을 얻는다.As described above, in the state of printing by the resin plate 22 or the flexographic plate 22, a UV etching printed matter of the offset printing method is obtained by using the UV automatic drying method as before.
본 발명에 따른 옵셋인쇄기에 의한 에칭인쇄과정을 살펴보면 도 5에 도시된바와 같이, 잉크롤러에 의해 판통전체에 잉크가 묻혀지고, 상기 판통 전체에 묻혀진 인쇄판이 설치된 블랭킷의 화선부에 잉크가 전이되며, 상기 블랭킷의 화선부에 전이된 잉크가 블랭킷과 압통사이를 통과하는 인쇄용지에 찍혀진 후 상기 잉크가 전이된 인쇄용지를 UV 자동건조방식으로 건조시켜 완성된다.Looking at the etching printing process by the offset printing machine according to the present invention as shown in Figure 5, the ink is buried in the whole plate by the ink roller, the ink is transferred to the line portion of the blanket is installed, the printing plate buried in the whole plate, After the ink transferred to the line of the blanket is printed on the printing paper passing between the blanket and the tender, the printing paper on which the ink is transferred is dried by UV automatic drying.
전술한 바와 같이 기존에는 판통을 인쇄판으로 사용하던 것을 본 발명에서는 블랭킷을 인쇄판으로 사용하여 기존 옵셋인쇄에서는 인쇄용지면에 오돌토돌하게 형성되는 에칭인쇄면의 높이가 0.4㎛ ~ 0.6㎛ 정도로 구현할 수 있었으나 본 발명에 따른 옵셋인쇄에서는 약 10㎛의 에칭인쇄면의 높이를 얻을 수 있다. 즉 기존의 실크스크린 인쇄와 같이 에칭인쇄면의 높이를 20㎛까지 향상시킬 수는 없었지만 약 10㎛까지 높이면서 인쇄속도에 있어서는 옵셋 인쇄의 장점인 신속한 인쇄로 인하여 수배의 생산성 향상을 가져왔다.As described above, in the present invention, a plate is used as a printing plate. In the present invention, a blanket is used as a printing plate. However, in the conventional offset printing, the height of the etching printing surface which is formed on the printing surface is about 0.4 μm to 0.6 μm, but the present invention can be realized. In offset printing according to the above, the height of the etching printed surface of about 10 μm can be obtained. In other words, it was not possible to improve the height of the etched print surface up to 20㎛ like the conventional silkscreen printing, but it has increased productivity to several times due to the rapid printing which is the advantage of offset printing in printing speed while increasing to about 10㎛.
