[0056] Then the material of the traction component 80 is guided by a plurality of unwinding guide rollers; after the paper path is corrected by the first deviation correction component 11; it enters the workstation position of the digital printing component 40 for printing.

[0057] After the processing is completed, it enters the detection component 50, and the camera conducts real-time detection on the printed material; if defects are detected in the material printing, an alarm is given to remind the operator to troubleshoot the faults; if no defects are detected in the material, it enters the next process.
