一是印刷纸张的定位，即印刷机械规矩部件问题所造成的印刷套印印刷不准；二是印刷纸张在传递还有交接的时候，因为交接的不稳，造成印刷纸张相对位置发生了较大变化从而使套印印刷不准确。另外，印刷纸张在滚筒上面被剥离的时候，因为受到粘附力还有张力影响，如果叼纸不能克服剥离力的时候，就会使印刷纸张发生抽动，出现位移情况。
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.
针对书刊套印印刷精度不良的原因，应该采取一下相应的控制措施，来达到印刷套印的准确目的。对印刷印版进行烘烤处理，在校版的时候一定要进行规范操作，印刷印版夹位置应该居中，印刷印版上正，然后把夹版螺丝紧固好。
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.
