The die-cutting and indentation process is based on design requirements to cut or stamp the edges of printed materials into various shapes, add a special artistic effect to the printed materials, and achieve a certain functional use. The process of punching and cutting the substrate into a certain shape is called die-cutting; The process of using steel wire to press marks or leave groove marks that are conducive to bending on the substrate is called indentation.

模切用的印版称为刀版或轧刀。常用的刀具是带锋口的钢线，在夹具上弯成各种所需要的形状，再组成印版。圆压圆殂式的模切装置又称轮转模切机，其使用的模切压痕版分为两种，种是用完整的材料雕刻而成的，这种刀具的制作需要专门的设备，成本较高，但经久耐用；第二种是模切压痕版，做在一个薄的铁皮上，再包在滚筒上面而制成的。压痕线的版材也是钢线，只是比刀线略低，没有锋口，特殊图形的无缝刀具用整块钢版制成的。

The printing plate used for die-cutting is called a knife plate or a rolling knife. The commonly used tool is a steel wire with a sharp edge, which is bent into various desired shapes on a fixture and then formed into a printing plate. The circular pressure circular die cutting device, also known as the rotary die cutting machine, uses two types of die cutting indentation plates. The first type is carved from complete materials, and the production of this type of tool requires specialized equipment, which is expensive but durable; The second type is a die-cutting indentation plate, made on a thin iron sheet and then wrapped on a drum. The plate material for the indentation line is also steel wire, which is slightly lower than the blade line and has no sharp edges. The seamless cutting tool with special graphics is made of a whole steel plate.

平面形的模切压痕版的制作，大致分为两个阶段：阶段先做好底版，第二阶段将钢线剪好，按切线轨迹弯制成各种刀型，排放在底版内。

The production of flat die-cutting indentation plates can be roughly divided into two stages: the first stage is to prepare the base plate, and the second stage is to cut the steel wire and bend it into various knife shapes according to the tangent trajectory, which are placed inside the base plate.

模要压痕底版有金属底版和木板底版两种。金属底版有浇铅版、钢型版等几种。木板底版有胶合板、木板、锌木合钉板等种类。我国目前模切压痕版主要采用多层木胶合板。就是把拼版设计图转移到厚度为15-22mm的胶合板上，在线条和钻洞锯缝，再把模切刀和压痕线先按照每段盒型刀线的长度将模切刀和折缝线嵌到木板上，制成模切板。用来对模切刀的压痕加工的专用设备方根有刀片裁切角机等。

There are two types of impression plates for molds: metal plates and wooden plates. There are several types of metal base plates, such as cast lead plates and steel type plates. There are various types of wooden boards, such as plywood, wooden boards, and zinc wood nail boards. At present, the die-cutting indentation plate in China mainly uses multi-layer wood plywood. It means transferring the assembly design drawing to a plywood board with a thickness of 15-22mm, sawing the lines and drilling holes, and then embedding the die-cutting knife and crease line onto the wooden board according to the length of each box shaped blade line using the die-cutting knife and crease line to make the die-cutting board. The specialized equipment used for indentation processing of die-cutting knives includes blade cutting angle machines, etc.
