在印刷过程中，都会出现各种各样的问题，其中包括印刷工艺、印刷油墨、印刷生产等各种问题，印刷双影是现在要的问题，印刷字迹笔划边沿呈反翘状，印刷出现双影，这是印刷生产过程中常见的问题之一，下面我们就来一下印刷双影的问题。

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.

调整压力

Adjust pressure

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。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。

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, and 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.

版面设计

layout

在实际的济南印刷生产过程中，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。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 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.

要想制作出来精美的印刷产品，就要在印刷时注意很多，当然不仅是要在印刷时注意，在设计时也需要注意，以上就是对印刷双影的问题的方法，印刷时要多加注意。更多问题就来网站www.xinfengyinshua.cn咨询吧！
