The principle of printing and using valuable tickets (vouchers) should be based on

1. Printing and ordering must entrust professional companies with safety management.

2. When designing a ticket (voucher) pattern, a complex pattern (color gradient, microtext, relief effect, manual pattern encryption, etc.) should be used, and the original regular pattern should be changed to a random pattern to prevent imitation.

3. 1 The special security and anti-counterfeiting papers (watermarked papers, patterns can be customized as required) or dry carbon paper should be selected. 2 The raw materials should fully reflect its physical properties (bronzing, concave and convex surface treatment), chemical properties (colorless ink, fluorescent ink, photochromism, transparency, temperature change, magnetic ink, etc.).

4. Codes should be magnetic code and special numbering machines (fonts can be chosen).

5. Time Limit (Lifetime): Any anti-counterfeiting has a time limit, and it must not be changed in order to avoid imitation.

6. Ease of identification: Although any security ticket (voucher) has been produced with tighter anti-counterfeiting measures, it is more necessary for users to easily identify it.

7. Establish a rigorous protection concept: All processes should be treated with the same care as banknotes in order to prevent problems.
