济南印刷出现双影的解决方法是什么?

来源:http://www.xinfengyinshua.cn/   发布时间:2020-09-11
印刷是一个大家耳熟能详的话题,不管是企业还是零散商家,超市等打折季,都能看到商场的货架上进门的广告宣传栏上都发放有精美的折页画册等,济南印刷厂表面看上的精美画册实质上也有很多工艺的。下面我来知道了一些印刷当中出现的双影该怎么解决。
Printing is a well-known topic. Whether it's enterprises or scattered businesses, supermarkets and other discount seasons, you can see that there are exquisite folding picture albums on the shelves of shopping malls and the advertising billboards at the entrance. The exquisite picture books on the surface of Jinan printing factory also have many crafts. Now I'll know how to solve the double image in printing.
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,印刷双影是现在要解决的问题,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,下面我们就来解决一下印刷双影的问题。
In the printing process, there will be a variety of problems, including printing technology, printing ink, printing production and other problems. Printing double image is the problem to be solved now. The edge of printing handwriting is inverted, and there is double image in printing. This is one of the common problems in the printing production process. Let's solve the problem of printing double image.


一:检查印版
1: Check the plate
印版的字迹笔画过此,产生双影的原因很多,但最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 image of the printing plate, but the most direct reason is that the surface of the thin handwriting is not smooth and uneven, or the printing is caused by pressure. In order to achieve a satisfactory printing effect, such as poor transfer of printing plate to ink and other factors, it requires that the technical equipment, printing plate, paperboard, ink and auxiliary materials should be properly matched.
二:调整压力
2: Adjust the 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 the anilox roller and the printing wheel, and the downward pressure refers to the gap between the printing wheel and the printing roller. The larger the pressure, the smaller the clearance; the smaller the pressure, the larger the clearance. The effect of overpressure and overpressure is different. When the double image appears, you should carefully observe the printing effect. If the double image appears around the handwriting stroke, it is caused by excessive overpressure. The up pressing should be appropriately reduced, that is, the gap between the anilox roller and the printing wheel should be appropriately enlarged, subject to the direction of paper feeding. If the double image appears below the paper feeding direction, it is caused by excessive down pressing. To reduce the press down, that is, to increase the gap between the printing wheels, the effect will be improved.
三:版面设计
3: Layout design
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。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,首先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 the field version and the small type layout. In the printing process, if we want to print the field version flat and full, the pressure should be appropriately greater, but at the same time, it will cause the phenomenon of small print reproduction. In addition to the above factors, there are other factors, such as poor ink transfer, uneven paperboard, uneven compressive strength. In printing, to achieve a bright color, full, good coverage effect, the first consideration is to adjust the parameters of the equipment, including pressure. Although the cushion can play a good role in buffering, it can not fundamentally avoid the possibility of double shadow.
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解决的方法,印刷时要多加注意。
If you want to produce exquisite printing products, you should pay attention to a lot in printing. Of course, you should pay attention not only to printing, but also to design. The above is the solution to the problem of printing double image, and more attention should be paid to printing.
