After receiving the customer's film, it will be sent to the prepress department to make a Plate, followed by printing, after the bottom and the surface are printed, it will need to undergo high temperature compounding (a plastic card is composed of four layers of plastic, divided into two layers and two layers on the bottom surface) Protective layer), after compounding, the fine card beer will be discharged.
Every process in production needs to go through quality testing, and to the last general test, the quality is not up to standard.
Tape card smart card has another process
The tape on the tape card is attached to the protective layer before compounding, that is, it is different from the ordinary plastic card. The tape is added before compounding, and other processes are no different.
As for smart cards, the previous part of the process is the same as above. After the printing of the card body of each smart card is completed, it is the process of mounting the chip, reading, writing and testing.
Before loading the chip into the plastic card, it will be tested whether it is intact; then a small hole will be carved in the card body, the chip will be embedded in the small hole, and the chip will be added with appropriate information after installation.
Some credit cards are sent to other departments to add holograms after the card body is printed.
Pay attention to the temperature during the printing process
Undoubtedly, printing a high-quality product requires careful attention to each process, but there are always some parts that need extra attention. Printed plastic cards will pay special attention because of the temperature and pressure involved in compounding. The temperature and pressure during compounding must be controlled properly, otherwise the plastic card will expand or contract, or even the four-layer plastic compounding is not firm.
In addition, the pattern design of the card surface should also try to match the effect that its printing technology can achieve.
