What does the printing die-cutting machine do?

Generally speaking, if the printed product is rectangular, the finished product can be cut directly with a paper cutter. But if it is not rectangular, then you need to use a knife version (knife die) to card (die-cut) molding. Die cutting machine (box cutter) is the person who completes this process. In addition, when the printed matter needs indentation, this process also needs die cutting machine to complete. In some printing plants, the die-cutting machine needs to take into account both the broken line (dotted line) and the serial number (serial number on printed matter) (operating the disc machine).
