In addition to its practical value, plastic cards are also easy to carry. In addition to the improved technology for manufacturing I.C. wafers, the chips can be small enough to be buried and used in plastic cards, which enhances the I.C. card as a medium for computer systems.
General plastic card printing process
After receiving the order, it will depend on the customer's request or which printing method the product is suitable for. It means that the product can be obtained by using offset printing or screen printing (the advantages of offset printing and screen printing). For the desired effect, one of the printing methods is implemented.
After receiving the customer's film, it will be sent to the prepress department for plate making, followed by printing, the bottom and the surface are printed, then the high temperature composite is required (a plastic card consists of four layers of plastic, divided into two layers and two layers Protective layer), after the compounding, the fine card beer will be discharged.
In each process of production, quality testing is required, and the final total test is taken out, and the quality is not taken out.
Tape card smart card another process
The tape on the tape card is attached to the protective layer before the compounding, that is, the difference with the ordinary plastic card. The tape is added before the compounding, and the other processes are not different.
As for the smart card, the previous part of the process is as described above. After the card body of each smart card is printed, it is the process of embedding the wafer, reading, writing and testing.
Before the wafer is loaded into the plastic card, it will be tested first. It will be carved into a small hole in the card body, and the wafer will be embedded in the small hole. After the device is installed, the wafer will be properly loaded.
Some credit cards are sent to other departments and holograms after they are printed.
Pay attention to the temperature during the printing process
Undoubtedly, printing a high-quality product, each of which requires careful attention, but there are always some parts that need extra attention. The printed plastic card will pay special attention to the temperature and pressure involved in the compounding. The temperature and pressure during compounding must be controlled just right, otherwise the rubber card will expand or shrink, and even the four-layer plastic compound will not be firm.
In addition, the design of the card surface should also be matched with the effect that its printing technology can achieve.
Quality control by guidelines
For Toppan information cards, they regard each employee as a technician and have sufficient skills and experience to cope with the work. The staff responsible for quality testing selects and analyzes the "bad card" every day. After an order is completed, it will distribute the detailed results of the analysis to different departments, so that the departments can understand that they can improve. The place.
Of course, there will be different requirements for different orders. Therefore, before making each order, the department head will pre-list the chart to indicate where the order should be noted or at what angle, and the staff can follow the guidelines. Do your part.
