Cutting is also an important aspect of post-processing of digital printing. The first is the cutting of paper. Like traditional printing, digital printing also uses a paper cutter to cut the paper or finished product into the required size and shape. At present there are various paper cutters on the market, both manual and computer-controlled full-automatic types. The cutting specifications of single-sided knife cutters are mostly in the range of 52-150cm. Generally speaking, a paper cutting machine with a cutting width of 78cm is more suitable for digital printing. If possible, a computer-controlled paper cutting machine can better cooperate with digital printing because it can store a certain amount of data.
        In this way, if you cut a job that has been processed, you only need to call up the original program from the computer, which can fully save the time of tuning. In the use of the paper cutter, in order to protect the sharpness of the blade and extend the life of the paper cutter, the thickness of the paper to be cut at a time should not exceed 40mm, and the pressure of the paper cutter on the paper should be appropriate. Generally, soft paper The required pressure is higher, and the harder materials require relatively less pressure.

        It is critical to maintain the sharpness of the blade when using a computer cutter. Pay attention to the proper maintenance and use of the blade. Once the blade is blunt, the blade should be reground, otherwise it will affect the cutting accuracy. In addition, care must be taken to keep the ambient temperature at 19 to 23 ° C and the relative humidity at 50%. Under such conditions, the characteristics of the paper are relatively stable, which is conducive to the correct use and maintenance of the cutter, because the determination of many cutting parameters depends on the paper being processed.
