所谓重影就是用一块印版印出的图像错移,在印张上能够看到双重、三重的图影。济南宣传单页印刷厂家提示我们,造成重影的原因有多种,比如纸张、叼牙、滚筒、橡皮布、印速、油墨黏度等各种因素非常复杂。可以采用下述方法来检查原因并处理。
The so-called duplication is to use a plate to print the image offset, in the printing can see double, triple images. Jinan Publicity sheet printing manufacturers remind us that there are many reasons for duplication, such as paper, teeth, drum, rubber cloth, printing speed, ink viscosity and other factors are very complex. The following methods can be used to check the causes and deal with them.
①检查滚筒包衬和印刷压力。
Check cylinder liner and printing pressure.
②查看纸张适性。纸张适性不良,特别是在叼口部位起波浪的纸张,容易发生重影,故要进行检查。
Check the paper suitability. Paper with poor adaptability, especially the paper with wavy mouth, is prone to duplication, so it should be checked.
③检查橡皮布的张力,新的橡皮布容易松弛,注意分次收紧,但也不可过于绷紧。
(3) Check the tension of rubber cloth, new rubber cloth is easy to relax, pay attention to tightening step by step, but not too tight.
④印刷两次,观察套印精度,对侧规拉纸力,进纸、压纸轮、压纸机件进行检查调节。

(4) Printing twice, observe the overprint accuracy, check and adjust the side gauge drawing force, feed, press wheel and press parts.

⑤降低油墨的黏度。油墨黏度高,纸张不能顺利剥离橡皮布,使纸张的拖梢部分不稳定,从而产生重影。可以适当降低油墨的黏度。
Reduce the viscosity of ink. Ink viscosity is high, paper can not peel off rubber cloth smoothly, so that the end of the paper is unstable, resulting in ghosting. It can reduce the viscosity of ink appropriately.
⑥叼牙的调节。叼牙的调节不良和保养不当,是造成重影的一大原因。因此应定期做好叼牙的调节和维护检查,使之经常保持良好的工作状态。
Adjustment of teeth gripping. Poor regulation and improper maintenance of teeth are one of the major causes of duplication. Therefore, the regulation and maintenance of teeth should be done regularly to keep them in good working condition.
