The printing effect of flexographic printing machine is a problem that people are more concerned about, so in the actual production process, how to ensure the printing effect of flexographic printing machine?
1. Tension control part
The unwinding part needs to be done during unwinding: the film roll is large and the tension is small; the film roll is small and the tension is large. The receiving part requires: the film roll is small and the tension is small; the film roll is large and the tension is large. That is to say, the tension of the unwinding film should be small, and as the film roll decreases, the tension should gradually increase. When the rewinding film is unrolled, the tension should be small, and as the film roll increases, the tension will gradually increase. When printing, the printed matter is the paper or film of the printed matter, and the tension must always be kept constant. The tension of the paper or film is stable when discharging, and the tension of the receiving paper or film is also stable. The printed matter will not run off the edition, in order to maintain the accuracy of the edition.
2. Transfer guide roller
Numerous threading guide rollers not only require smooth and flexible rolling, but also require excellent dynamic and static balance processing. Just imagine that if each guide roller passes through a little resistance of the printed matter, it is difficult to ensure the accuracy of the printed matter due to the asynchronous resistance and static electricity that occurs during the printing of the printed film.
