Because of the continuous running of equipment, workers for uploading and downloading wont be idle during color switch. 6. Low producing cost per ton. Because of the continuous running of equipment, the use ratio of workers, heat energy and electric energy is extremely high, thus the loss of every link comes extremely low.
