There are 5 offset printing machines in UDN. All of them are 6 color printing machine with UV system. The characters of our printing machines are:

1. 100% print without head. Under this circumstance, we can print over the shoulder and aline the head with the artwork. Furthermore, we don’t need to cut the junk head to have the oval tube after printing.
2. 100% fire treatment. We don’t use crona to make the surface treatment to prevent the defect of sealing.
