The local tax invoice has the following anti-counterfeit signs: first, the invoice is printed on watermarked paper, and the watermark pattern is Diamond, marked with SW in the middle. Second, the invoice supervision seal and invoice number are printed with colored fluorescent (Security anti-counterfeit) ink. The printing color is large red and orange red is displayed under the ultraviolet light.
========================================================== ========================================================== =====
How to identify true and false invoices, professionals say, there are three basic methods: one is to look at paper; the other is to look at the financial seal; the third is to look at the quality of printed tickets.

Because the real invoice uses special counterfeit paper, hand-sensing is more flexible, and the diamond watermark is visible from both sides of the front and back, its lines are not printed by external force, visible through the light is more transparent, the lines are round; the fake ticket is smooth, hard, and brittle. The diamond watermark is drawn from the light as if using a line. It has no passthrough effect. from the back of the paper, the lines of the diamond mark have external force suppression marks. In addition, the operator usually does not include a financial seal that matches the business name on the fake ticket. The stamp is rather vague and intentionally hard to identify.
