一是印刷紙張的定位，即印刷機械規(guī)矩部件問題所造成的印刷套印印刷不準；二是印刷紙張在傳遞還有交接的時候，因為交接的不穩(wěn)，造成印刷紙張相對位置發(fā)生了較大變化從而使套印印刷不準確。另外，印刷紙張在滾筒上面被剝離的時候，因為受到粘附力還有張力影響，如果叼紙不能克服剝離力的時候，就會使印刷紙張發(fā)生抽動，出現(xiàn)位移情況。
First, the positioning of printing paper, that is, the inaccurate overprint caused by the problems of regular parts of printing machinery; Second, when the printing paper is transferred and handed over, the relative position of the printing paper has changed greatly due to the unstable handover, which makes the overprint printing inaccurate. In addition, when the printing paper is peeled off on the drum, due to the influence of adhesion and tension, if the paper can not overcome the stripping force, the printing paper will twitch and displace.
針對書刊套印印刷精度不良的原因，應該采取一下相應的控制措施，來達到印刷套印的準確目的。對印刷印版進行烘烤處理，在校版的時候一定要進行規(guī)范操作，印刷印版夾位置應該居中，印刷印版上正，然后把夾版螺絲緊固好。
In view of the reasons for the poor printing accuracy of book overprint, we should take corresponding control measures to achieve the accurate purpose of printing overprint. The printing plate shall be baked, and the standard operation must be carried out when checking the plate. The position of the printing plate clamp shall be centered, the printing plate shall be aligned, and then the clamping screw shall be fastened.
