Die-cutting Process

Die cutting is the post process section of the printing process. By applying mechanical pressure to the template, the printed matter is pressed into a certain shape to produce an indentation line, which is folded into a beautiful outer package.

The traditional post printing production technology of cigarette label includes concave convex and die cutting, that is, the same printed matter can be completed only after two times of equipment pressure. For a long time, starting from the common point of concave convex and die cutting technology, the concave convex plate is attached to the die cutting plate, and the traditional two-time technology - concave convex and die cutting is completed through one-time pressure of the equipment. After a long time of testing and technical training, the production cost is reduced and the utilization rate of the equipment is improved. The basic requirements are as follows:

   1、 The pressure should be balanced. That is, under the same pressure, both die-cutting forming and concave convex effect can be achieved, which is the key to the implementation of "concave convex + die-cutting" technology. Adjust the concave convex pressure based on the die cutting pressure. Do not lower the version when the die-cutting pressure is too heavy or too light, otherwise the previous efforts will be wasted even if the concave convex effect is achieved.

   2、 The color level should be balanced. That is, the two color levels shall be unified during version adjustment or production. Do not ignore the head and tail, and operate the die-cutting and concave convex color levels independently. During version adjustment, the concave convex effect must be adjusted when the die-cutting color level is accurate.

   3、 The mass should be balanced. That is, during production sampling, its quality inspection scope should be the sum of concave convex and die-cutting.

Of course, not all products can be completed by "concave convex + die cutting" one-time pressure. It requires that the concave convex on the same printed matter is far away from the knife and line. Otherwise, it will not only affect the forming effect of the cigarette box, but also cause defects such as weak three-dimensional sense of concave convex and unclear layers.
