Carving gravure of business card printing and membership card making production and offset business card printing and membership card making, and so on are very different, first of all the manuscripts submitted to approx 10 times, the perimeter line by hand is decisived on top of a piece of zinc tablet with a smaller machine to get an outside line back into the original large carved in a piece about an inch of eight brass, and copper strip it is some anticorrosive toppedwith films, because of copper strip is triggered from the perimeter line, so the rough body by hand for the film, when removed, and then use the medicine to the erosion of deep water, and proto-end knife with a magnifying glass and, thetolerant to the edge, sharp corners repaired, such as location on a layer of chrome, it's a printing plate.

雕刻凹版的制卡和会员卡制作制作与柯式制卡和会员卡制作等有很大的分别，首先把来稿放大约十倍，把外围线用手工刻划在一块锌片之上，再用一部缩细机械把外线缩回原大刻在一块约八份一寸的铜片上，而这件铜片上是涂有一些防腐蚀薄膜的，因为铜片只是勾上字的外围线，所以要用手工将粗身地上的薄膜刮去，然后用药水将印纹蚀深，最后仍要用放大镜及雕刻刀，耐性地将线边、尖角等位置修好，再镀上一层铬，这印版便大功告成。
