Signature fonts include image signature, combination signature, flower signature, vertical signature, anti-counterfeiting signature, digital signature, letter signature and reverse signature.

Vertical sign is a top-down signature, and the name is vertical sign. Vertical signing is the earliest form of signature in China, and it is also one of the most basic forms of signature in modern times. Vertical signature is mainly used to sign the signed object with vertical text content, which is widely used in calligraphy and painting works and can also be used for the signed object without text content.

Anti-counterfeiting signature is a special signature text designed to prevent others from forging. Its style and layout are meticulous, the schema is changeable, and the transformation and generation methods are diverse, which intentionally increases the writing difficulty of some strokes, or makes some anti-counterfeiting arrangements in some strokes, which is difficult to imitate.

Digital label, letter label and reverse label are the other two forms of anti-counterfeiting label. The signer skillfully uses numbers or letters to change the name into a string of numbers or letters, which looks like numbers or letters, but it is actually Chinese.
