How to distinguish seals?

If it is a seal made by computer software, it will be absolutely horizontal, while manual stamping is generally not absolutely horizontal, and there will be a certain degree of inclination. Moreover, the seal printed by the computer will completely cover up the uniform color of the ink below, while the seal with inkpad will reveal the characters with uneven ink color and irregular seal edge below. In addition, the font of the official seal is generally Song Ti and imitation Song Ti. If it is another font, it is not necessarily a fake seal, but pay attention.

The following is a network reference.

First of all, identify from the seal font and name arrangement direction. According to the regulations, the seal is printed in Song Dynasty and simplified characters promulgated and implemented in the State Council; The seal of the people's government of the ethnic autonomous region shall be in both Chinese and the local commonly used national languages. The name of the seal shall be the legal name of the organ, organization, enterprise and institution. There are too many words printed on the seal, so you can use a commonly used abbreviation appropriately. Seal arrangement should be around the central symbol, along the inner side of the circle line outside the official seal, and the names of functional institutions or offices of each unit should be arranged horizontally from left to right perpendicular to the unit name. Printed fonts should be arranged neatly and beautifully, with the same font length and size, equal spacing, appropriate density and consistent height. If the seal is found to be under any of the following circumstances, it can be judged as a fake seal. ?

1, the seals of ethnic regional autonomous areas do not use ethnic languages, or use ethnic languages that are not commonly used by local governments; ?

2. The seal font uses simplified characters that have been explicitly abolished in the State Council or private simplified characters that have not been officially used by the state; ?

3. The seal font uses non-Chinese characters; ?

4. The name of the seal is illegal or uses a non-common abbreviation; The name of the seal should be crowned instead of crowned; ?

5. The seal font arrangement order is not in conformity with the provisions; ?

6. The font size in the printed text is different, the high and low backgrounds are different, the density is different, or the font is skewed but inconsistent with the direction of the radius line. ?

Second, identify from the position of the seal. In documents such as certificates, certificates and contracts, it is necessary to affix seals, and the position of seals in them also has certain rules. If one of the following conditions is found, it may be a fake seal. ?

1. There is no seal on the certificate photo or the seal on the photo does not match the external seal of the photo; ?

2. Important documents to prove identity, such as work permits and diplomas of government officials, are not stamped with steel seals on their photos; ?

3. The seal on the document is undated or obviously stamped first and then dated; ?

4. The seal appears too off center or even upside down. ?

Third, identify it from the effect of the outer circle line of the seal. All seals have excircle lines, and the excircle lines of real seals should be circles with uniform thickness, and the printed words appear smooth and clear with uniform thickness. On the contrary, the fake seals privately carved by criminals have uneven thickness, non-round, intermittent, light and heavy, rough lines and blurred lines.
