印刷是一个大家耳熟能详的工艺，但是在印刷过程中，都会出现各种各样的问题，其中，包括印刷双影，这是印刷生产过程中常见的问题之一，那么，印刷中出现双影应该怎么办呢？济南印刷包装厂家为您讲解问题点。

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.

印版的字迹笔画过此，产生双影的原因很多，但直接的原因细字迹笔画表面不平滑、不均匀，或印是压力造成的。要在生产中达到一个满意版对墨的转移性不良等因素，都可能出的印刷效果，就要求作人员的技术设备、印版、纸板、水墨、辅助材料搭配得恰到好处。

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.

这里的压力分为上压和下压，上压是指网纹辊和印刷轮之间的间隙大小下压是指印刷轮与印刷压轮之间的间隙大小。压力大则间隙小，压力小则间隙大。上压过大和下压过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.

出现双影的时就要仔细观察印刷效果，如果双影出现在字迹笔划周围，便是上压过大造成的，要将上压适当减少，也就是网纹辊和印刷轮的间隙适当放大一些，以进纸的方向为准，如果双影出现在进纸方向下方的话，那就是下压过大造成的。要将下压适减小，也就是将印刷轮之间的间隙调大一些，效果就会有所改善。

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.

在实际的生产过程中，经常会遇到实地版和小字版面的情况，印刷过程中，要想实地版印得平实，饱满一些，压力就要适当的大一些，但同时又会使小字产生重影的现象。

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，还有其它因素，如水墨本身的转移性不良，纸板不平整，抗压强度不均等。在印刷时，要达到一个颜色鲜艳、饱满、覆盖力好的效果，考虑的就是调整设备的参数，包括压力。虽说用衬垫能很好地起到缓冲的作用，但依旧不能从根本上避免产生双影的可能。

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.
