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。济南画册印刷期间出现重影的原因有多种，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 double image is that the image printed by a printing plate is staggered, and the double and triple images can be seen on the printing plate. There are many reasons for duplication during Jinan album printing, such as paper, teeth, roller, blanket, 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。

① Print twice, observe the overprint accuracy, check and adjust the side gauge paper pulling force, paper feeding, paper pressing wheel and paper pressing machine.

②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。

② Check the tension of the rubber blanket. The new rubber blanket is easy to relax. Pay attention to tighten it in several times, but do not tighten it too much.

③检查滚筒包衬和印刷压力。

③ Check the cylinder lining and printing pressure.

④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。

④ Check the paper suitability. The suitability of the paper is poor, especially the paper with waves at the mouth is easy to duplicate, so it should be checked.

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。

⑤ Reduce the viscosity of the ink. The ink viscosity is high, and the paper can not peel off the blanket smoothly, which makes the trailing part of the paper unstable, thus producing ghosting. The viscosity of the ink can be appropriately reduced.

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。

⑥ Adjustment of teeth. The bad adjustment and improper maintenance of the teeth in the mouth are the main reasons for the ghosting. Therefore, the adjustment, maintenance and inspection of the teeth should be done regularly to keep them in good working condition.
