In the printing process, there will be various problems, including printing process, printing ink, printing consumption and other issues. Printing double shadow is the problem to be dealt with now. Printing handwriting edge is inverted warping, printing double shadow is one of the common problems in the process of printing consumption. Here we will deal with it. The problem of printing duplicates.

一：檢查印版

First: Check the printing plate

印版的字跡筆畫(huà)過(guò)此,產(chǎn)生雙影的緣由很多,但直接的緣由細(xì)字跡筆畫(huà)外表不平滑、不平均,或印是壓力形成的。要在消費(fèi)中到達(dá)一個(gè)稱(chēng)心版對(duì)墨的轉(zhuǎn)移性不良等要素,都可能出的印刷效果,就請(qǐng)求作人員的技術(shù)設(shè)備、印版、紙板、水墨、輔助資料搭配得恰如其分。

There are many reasons for the double-shadows of the printed handwriting and strokes, but the direct reason is that the appearance of the fine handwriting and strokes is not smooth, uneven, or the printing is formed by pressure. In order to achieve a satisfactory version of the transfer of ink and other elements in consumption, the printing effect may be produced, the technical equipment, printing plate, cardboard, ink, auxiliary materials are requested to match appropriately.

二：調(diào)整壓力

II. Adjusting 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。呈現(xiàn)雙影的時(shí)就要認(rèn)真察看印刷效果,假如雙影呈現(xiàn)在字跡筆劃四周,便是上壓過(guò)大形成的,要將上壓恰當(dāng)減少,也就是網(wǎng)紋輥和印刷輪的間隙恰當(dāng)放大一些,以進(jìn)紙的方向?yàn)闇?zhǔn)，假如雙影呈現(xiàn)在進(jìn)紙方向下方的話(huà),那就是下壓過(guò)大形成的。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 upper pressure and lower pressure. The upper pressure refers to the gap between the screen roller and the printing wheel. The lower pressure refers to the gap between the printing wheel and the printing wheel. When the pressure is large, the gap is small, and when the pressure is small, the gap is large. Over-pressure and over-pressure printing have different effects. When presenting double shadows, we should carefully observe the printing effect. If the double shadows appear around the handwriting strokes, they are formed by overpressure. We should reduce the overpressure appropriately, that is, to enlarge the gap between the screen roller and the printing wheel appropriately, taking the direction of paper feeding as the criterion. If the double shadows appear below the direction of paper feeding, they are overpressure. Yes. The effect will be improved if the lower pressure is reduced, that is, the clearance between the printing wheels is increased.

三：版面設(shè)計(jì)

3: Layout design

在實(shí)踐的消費(fèi)過(guò)程中,經(jīng)常會(huì)遇到實(shí)地版和小字版面的狀況,印刷過(guò)程中,要想實(shí)地版印得平實(shí),豐滿(mǎn)一些,壓力就要恰當(dāng)?shù)拇笠恍?但同時(shí)又會(huì)使小字產(chǎn)生重影的現(xiàn)象。除了上面的要素外,還有其它要素,如水墨自身的轉(zhuǎn)移性不良,紙板不平整,抗壓強(qiáng)度不均等。在印刷時(shí),要到達(dá)一個(gè)顏色鮮艷、豐滿(mǎn)、掩蓋力好的效果,思索的就是調(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,但照舊不能從基本上防止產(chǎn)生雙影的可能。

In the process of practical consumption, we often encounter the situation of the field version and small print. In the process of printing, if we want the field version to print smoothly and fuller, the pressure should be more appropriate, but at the same time it will cause the phenomenon of duplication of small characters. In addition to the above factors, there are other factors, such as poor transfer of ink itself, uneven cardboard, uneven compressive strength. When printing, in order to achieve a bright color, plump, good masking effect, the first consideration is to adjust the parameters of the equipment, including pressure. Although cushioning can play a good buffer role, but still can not basically prevent the possibility of double shadows.
