How to test the authenticity of the official seal?

1, look at the font

Company seals, including the official seal, contract seal, financial seal and legal person seal, must be made in the engraving company designated by the Public Security Bureau. The state also has standard requirements for the font of official seals. For ordinary companies and enterprises in China, the most common one is Song Style or Imitation Song Style. Although it is not absolute, if you use other fonts, please be suspicious and alert. The following two fake seals are not in Song Dynasty.

2. Look at this color

Generally speaking, from the computer, the color of the official seal inkpad is dark red. The most important thing is that there are many irregular spots in the color, either small black spots or small gaps. This is because the real seal is carved on the surface of the object after all, and the surface of the seal blank cannot be absolutely smooth. In the process of printing with inkpad, the white paper and the desktop below cannot be absolutely smooth because of uneven ink and inconsistent strength.

Computer-made fake seals are generally very uniform red, and the whole seal has no color difference, impurities and blanks.

Step 4 look at the angle

Refers to the angle of stamping. Although most people want to stamp correctly, there will always be some deviations, especially the circular seal is more difficult to grasp.

However, when a computer makes a seal, 100% must be a positive number by default. Let's take a look at the comparison of the true and false seals above. Although the correctness of the seal cover cannot judge the authenticity of the seal, as a clue to distinguish the fake seal, please use it comprehensively.

Step 5 look at the location

See if the official seal is stamped on the blank space of the agreement or on the text. Generally speaking, the real seal is stamped on the company name, while the shoddy fake seal likes to be stamped in the blank, because the fake seal is made by computer, and if it is stamped on the text, it will block the text behind.

But in order to look more authentic, fake seals with higher production level will also be stamped with words. At this time, you need to carefully look at the overlap between the words on the seal and the words printed on the paper. If the real seals overlap, the words behind can still be displayed by ink; The fake seal made by the computer will completely block the following words.
