Traditional die-cutting is a cutting process of post-processing of printed matter. Die-cutting technology can make printed matter or other paper products into die-cutting knives according to pre-designed patterns for cutting, so that the shape of printed matter is no longer limited to straight edges and right angles. Traditional die-cutting tools are combined into die-cutting plates according to the patterns required by product design, and under the action of pressure, printed matter or other plate-like blanks are rolled into the required shapes or cuts. Indentation technology is to press the line marks on the plate with a line knife or a line die under the action of pressure, or to roll the line marks on the plate with a line roller, so that the plate can be bent and formed at a predetermined position. Usually, the die-cutting and indentation process is a process of combining the die-cutting knife and the line pressing knife in the same template, and simultaneously performing die-cutting and indentation processing on the die-cutting machine, which is referred to as die-pressing. If you think about it, you can go to the die-cutting world, where all the materials are before die-cutting!
