Printing is a well-known topic. No matter in the discount season of enterprises, retail businesses, supermarkets and so on, you can see that there are beautiful folding albums distributed on the advertising billboards on the shelves of shopping malls. The beautiful albums on the surface also have many processes. Let me know how to solve some double shadows in printing.

在印刷過(guò)程中,都會(huì)出現(xiàn)各種各樣的問(wèn)題,其中包括印刷工藝、印刷油墨、印刷生產(chǎn)等各種問(wèn)題,印刷雙影是現(xiàn)在要解決的問(wèn)題,印刷字跡筆劃邊沿呈反翹狀,印刷出現(xiàn)雙影,這是印刷生產(chǎn)過(guò)程中常見(jiàn)的問(wèn)題之一,下面我們就來(lái)解決一下印刷雙影的問(wèn)題。

In the process of printing, there will be various problems, including printing process, printing ink, printing production and so on. Printing double shadow is the problem to be solved now. The stroke edge of printing handwriting is inverted, and printing double shadow occurs. This is one of the common problems in the process of printing production. Let's solve the problem of printing double shadow.

一：檢查印版

1： Check the printing plate

印版的字跡筆畫(huà)過(guò)此,產(chǎn)生雙影的原因很多,但直接的原因細(xì)字跡筆畫(huà)表面不平滑、不均勻,或印是壓力造成的。要在生產(chǎn)中達(dá)到一個(gè)滿意版對(duì)墨的轉(zhuǎn)移性不良等因素,都可能出的印刷效果,就要求作人員的技術(shù)設(shè)備、印版、紙板、水墨、輔助材料搭配得恰到好處。

There are many reasons for the double shadow caused by the strokes on the printing plate, but the direct reason is that the surface of the fine handwriting strokes is not smooth and uneven, or the printing is caused by pressure. In order to achieve a satisfactory printing effect due to factors such as poor transfer of printing plate to ink, it is required that the technical equipment, printing plate, cardboard, ink and auxiliary materials of the workers should be properly matched.

二：調(diào)整壓力

2： Adjust pressure

這里的壓力分為上壓和下壓,上壓是指網(wǎng)紋輥和印刷輪之間的間隙大小下壓是指印刷輪與印刷壓輪之間的間隙大小。壓力大則間隙小,壓力小則間隙大。上壓過(guò)大和下壓過(guò)大印出的效果是不同的。出現(xiàn)雙影的時(shí)就要仔細(xì)觀察印刷效果,如果雙影出現(xiàn)在字跡筆劃周?chē)?便是上壓過(guò)大造成的,要將上壓適當(dāng)減少,也就是網(wǎng)紋輥和印刷輪的間隙適當(dāng)放大一些,以進(jìn)紙的方向?yàn)闇?zhǔn)，如果雙影出現(xiàn)在進(jìn)紙方向下方的話,那就是下壓過(guò)大造成的。要將下壓適減小,也就是將印刷輪之間的間隙調(diào)大一些,效果就會(huì)有所改善。

The pressure here is divided into up pressure and down pressure. Up pressure refers to the gap between anilox roller and printing wheel. Down pressure refers to the gap between printing wheel and printing pressing wheel. Large pressure leads to small clearance; small pressure leads to large clearance. The effect of overpressure is different from that of overpressure. In case of double shadow, it is necessary to carefully observe the printing effect. If the double shadow appears around the writing strokes, it is caused by excessive upward pressure. The upward pressure should be appropriately reduced, that is, the gap between the anilox roller and the printing wheel should be appropriately enlarged, subject to the paper feeding direction. If the double shadow appears below the paper feeding direction, it is caused by excessive downward pressure. To reduce the press down, that is, to increase the gap between the printing wheels, the effect will be improved.

三：版面設(shè)計(jì)

3： Layout design

在實(shí)際的生產(chǎn)過(guò)程中,經(jīng)常會(huì)遇到實(shí)地版和小字版面的情況,印刷過(guò)程中,要想實(shí)地版印得平實(shí),飽滿一些,壓力就要適當(dāng)?shù)拇笠恍?但同時(shí)又會(huì)使小字產(chǎn)生重影的現(xiàn)象。除了上面的因素外,還有其它因素,如水墨本身的轉(zhuǎn)移性不良,紙板不平整,抗壓強(qiáng)度不均等。在印刷時(shí),要達(dá)到一個(gè)顏色鮮艷、飽滿、覆蓋力好的效果,考慮的就是調(diào)整設(shè)備的參數(shù),包括壓力。雖說(shuō)用襯墊能很好地起到緩沖的作用,但依舊不能從根本上避免產(chǎn)生雙影的可能。

In the actual production process, we often encounter the situation of field edition and small print edition. In the printing process, if we want to make the field edition smooth and full, the pressure should be appropriately large, but at the same time, it will cause the small print to have a double image. In addition to the above factors, there are other factors, such as poor transfer of ink itself, uneven paperboard, and uneven compressive strength. When printing, to achieve a bright color, full and good coverage, the first consideration is to adjust the parameters of the equipment, including the pressure. Although the cushion can play a good role in cushioning, the possibility of double shadow cannot be fundamentally avoided.

要想制作出來(lái)精美的印刷產(chǎn)品，就要在印刷時(shí)注意很多，當(dāng)然不僅是要在印刷時(shí)注意，在設(shè)計(jì)時(shí)也需要注意，以上就是對(duì)印刷雙影的問(wèn)題解決的方法，印刷時(shí)要多加注意。

If you want to produce exquisite printing products, you should pay attention to a lot during printing, not only during printing, but also during design. The above is the solution to the problem of double shadow printing. You should pay more attention during printing.
