模切壓痕工藝是根據(jù)設(shè)計(jì)的要求，使印刷品的邊緣裁切或沖壓成為各種形狀，在印刷品上增加某種特殊的藝術(shù)效果，及達(dá)到某種使用功能，把承印物沖切成一定形狀工藝為模切；利用鋼線通過壓印，在承印物上壓出痕跡或留下利于彎折的槽痕的工藝稱為壓痕。
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.
模切用的印版稱為刀版或軋刀。常用的刀具是帶鋒口的鋼線，在夾具上彎成各種所需要的形狀，再組成印版。圓壓圓殂式的模切裝置又稱輪轉(zhuǎn)模切機(jī)，其使用的模切壓痕版分為兩種，種是用完整的材料雕刻而成的，這種刀具的制作需要專門的設(shè)備，成本較高，但經(jīng)久耐用；第二種是模切壓痕版，做在一個(gè)薄的鐵皮上，再包在滾筒上面而制成的。壓痕線的版材也是鋼線，只是比刀線略低，沒有鋒口，特殊圖形的無縫刀具用整塊鋼版制成的。
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.
平面形的模切壓痕版的制作，大致分為兩個(gè)階段：階段先做好底版，第二階段將鋼線剪好，按切線軌跡彎制成各種刀型，排放在底版內(nèi)。
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.
模要壓痕底版有金屬底版和木板底版兩種。金屬底版有澆鉛版、鋼型版等幾種。木板底版有膠合板、木板、鋅木合釘板等種類。我國目前模切壓痕版主要采用多層木膠合板。就是把拼版設(shè)計(jì)圖轉(zhuǎn)移到厚度為15-22mm的膠合板上，在線條和鉆洞鋸縫，再把模切刀和壓痕線先按照每段盒型刀線的長度將模切刀和折縫線嵌到木板上，制成模切板。用來對(duì)模切刀的壓痕加工的專用設(shè)備方根有刀片裁切角機(jī)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.
