In order to ensure the stability of the printing material before entering the printing unit, the unit type flexo printing machine often adopts automatic correction device. It can detect the deviation of the lateral position of a certain edge of the printing material and correct it in time, with an accuracy of up to 0.5mm. Generally, for opaque materials such as paper and aluminum foil, photoelectric sensors are often used; for transparent materials such as films, ultrasonic sensors are used. Once the printing material enters the printing area and the die-cutting rewinding area, the stability of its transverse position is guaranteed by the processing and installation accuracy of the machine itself and the parallelism between the rollers.
