印刷是一個(gè)大家耳熟能詳?shù)墓に嚕窃谟∷⑦^程中，都會(huì)出現(xiàn)各種各樣的問題，其中，包括印刷雙影，這是印刷生產(chǎn)過程中常見的問題之一，那么，印刷中出現(xiàn)雙影應(yīng)該怎么辦呢？濟(jì)南印刷包裝廠家為您講解問題點(diǎn)。

Printing is a familiar process, but in the printing process, there will be various problems, including printing double shadow, which is one of the common problems in the printing production process. Then, what should be done if double shadow occurs in printing? Jinan printing and packaging factory will explain the problems for you.

印版的字跡筆畫過此，產(chǎn)生雙影的原因很多，但直接的原因細(xì)字跡筆畫表面不平滑、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 when the handwriting of the printing plate is painted here, but the direct reason is that the surface of the fine handwriting is not smooth and uneven, or the printing is caused by pressure. In order to achieve a satisfactory printing effect in production due to factors such as poor ink transfer of the plate, it is required that the technical equipment, printing plate, cardboard, ink and auxiliary materials of the workers be properly matched.

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。上壓過大和下壓過大印出的效果是不同的。

The pressure here is divided into upper pressure and lower pressure. The upper pressure refers to the gap between the anilox roller and the printing wheel, and the lower pressure refers to the gap between the printing wheel and the printing press wheel. When the pressure is high, the clearance is small; when the pressure is low, the clearance is large. The effect of overpressure and overpressure is different.

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)在字跡筆劃周圍，便是上壓過大造成的，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。

When double shadows appear, it is necessary to carefully observe the printing effect. If double shadows appear around the handwriting 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. The direction of paper feeding should prevail. If double shadows appear below the direction of paper feeding, it is caused by excessive downward pressure. To reduce the press down properly, that is, to increase the gap between the printing wheels, the effect will be improved.

在實(shí)際的生產(chǎn)過程中，經(jīng)常會(huì)遇到實(shí)地版和小字版面的情況，印刷過程中，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。

In the actual production process, we often encounter the situation of the field version and the small print. During the printing process, if we want to print the field version flat and full, the pressure must be appropriately greater, but at the same time, the small print will have a double image.

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 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 the effect of bright color, fullness 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, it still cannot fundamentally avoid the possibility of double shadows.

要想制作出來精美的印刷產(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，以上就是對印刷雙影的問題的方法，印刷時(shí)要多加注意，更多內(nèi)容了解就來我們網(wǎng)站http://buiy.cn咨詢吧。
