作者:admin 来源:http://www.sdhzyw.com 发布时间:2016-8-23 15:38:46 浏览次数:392
用平版印刷机印刷,在滚筒每次滚压中,滚筒之间产生微小位移,相对应的质点不相重合,橡皮布上一次转移所剩余的墨层,不能与本次转移的墨层完全重合,除本次转移的墨层外,还同时画册印刷呈现剩余墨层的浅淡印迹,木相重合的深浅墨迹,同时呈现在承印物上,便形成了重影故障。
Lithographic printing machine printing. In each rolling drum, drum produce micro displacement, corresponding to the particle does not coincide, blanket on a transfer the remaining ink layer, not with the transfer of ink layer completely overlap, except the transfer of ink layer also printing pictures presented residual ink layer shallow imprinting, wood coincide with the shades of ink, also present in the substrate, they formed a doubling failure.
重影故障多发生在开始印刷时;滚筒合压和滚筒离压时;印版滚筒与橡皮滚筒的印刷面相接触和相分离时;橡皮滚筒和压印滚筒的印刷面相接触和相分离时;印版滚筒与传纸滚筒交接纸张时;靠版胶辊开始接触印版或脱开印版时及印刷速度变更时。

重影的类型,按照重影的方向,分为纵向重影、横向重影和A、B重影三种。
The type of shadow, in accordance with the direction of the shadow, is divided into three types: longitudinal, transverse, and A, and B.
纵向重影,也叫上下重影。网点的虚影在原网点的上、下端,与滚筒轴向垂直的方向上,其位置固定。
Vertical heavy shadow, also called up and down. The virtual shadow of the dot is arranged on the upper and the lower ends of the original network, and the direction of the axial direction of the roller is fixed.
横向重影,也叫来去重影。网点的虚影在原网点的左右侧,与滚筒的轴线方向平行或成一定的角度,虚影有轻有重,其位置固定。
Horizontal heavy shadow, also called the shadow. The virtual shadow of the dot is in the left and right sides of the original network, which is parallel to the axis of the roller or a certain angle, and the virtual shadow is light and heavy.
A、B重影,网点的虚影,有的在原网点的上、下侧,有的在原网点的左右侧,其位置不固定。A、B重影有时是每一印张上均有,有时却是隔一张或几张才有。
