在印刷过程中,都会呈现各种各样的问题,其中包括印刷工艺、印刷油墨、印刷消费等各种问题,印刷双影是如今要处理的问题,印刷字迹笔划边沿呈反翘状,印刷呈现双影,这是印刷消费过程中常见的问题之一,下面我们就来处理一下印刷双影的问题。
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:检查印版
First: Check the printing plate
印版的字迹笔画过此,产生双影的缘由很多,但直接的缘由细字迹笔画外表不平滑、不平均,或印是压力形成的。要在消费中到达一个称心版对墨的转移性不良等要素,都可能出的印刷效果,就请求作人员的技术设备、印版、纸板、水墨、辅助资料搭配得恰如其分。
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:调整压力
II. Adjusting 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。呈现双影的时就要认真察看印刷效果,假如双影呈现在字迹笔划四周,便是上压过大形成的,要将上压恰当减少,也就是网纹辊和印刷轮的间隙恰当放大一些,以进纸的方向为准,假如双影呈现在进纸方向下方的话,那就是下压过大形成的。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 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:版面设计
3: Layout design
在实践的消费过程中,经常会遇到实地版和小字版面的状况,印刷过程中,要想实地版印得平实,丰满一些,压力就要恰当的大一些,但同时又会使小字产生重影的现象。除了上面的要素外,还有其它要素,如水墨自身的转移性不良,纸板不平整,抗压强度不均等。在印刷时,要到达一个颜色鲜艳、丰满、掩盖力好的效果,思索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,但照旧不能从基本上防止产生双影的可能。
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.
