Gravure press is not discharge on down during the mode of production, the per-color business card printing and membership card after harvest cylindrical insertreleased, offline after the subject with a single eyefor a cross-cutting machine rolled business card printing and membership card making for easier and more precise printing long broken sected collection, and then set the broken sected collected leaflets business card printing and membership card making products in spinons convex, indentation, die-cutting, waste, collection, testing, packaging; business card printing and membership card making products for stamping or compact label positioning easy-care, and the increase in the operation, the disadvantage is that the above process, the operation covers an area of large plant, to make more, and sometimes the drum to the materials offline operation in cross-cutting precision |interrupted Zhang superstandard, it will be a large number of categorizing people and a large area of the workspace.

凹印机是采用上料下料不停机的生产方式，进行逐色制卡和会员卡制作后收成卷筒状取下，离线后通过一台识标横切机把卷状制卡和会员卡制作品以单幅印长断切收集，再将断切收集来的单张制卡和会员卡制作品进行棘凸、压痕、模切、剔废、收集、检验、包装；制卡和会员卡制作品如需要烫金或镭射标定位烫，还需增加工序，以上工艺缺点是工序多，占地面积大，使用机台多、人员多，有时卷筒印材离线作业在横切过程中断张精度超标，还需大量的分检人员和大面积的工作空间。
