The size of private printing is not specified, and it is about 1cm-2cm. Stamps are used as stationery printed on documents to indicate identity or signature. Common seals should be dyed with pigment before printing. If you don't touch the pigment, there will be bumps after printing on the plane, which is called steel seal. Made of metal, wood, stone, jade, etc.

The role of private seal:

1. The private seal is valid to the outside world, and sometimes it can replace the signature of the legal representative.

2. Financially, some bank bills must have a personal seal when they are used, and they should be backed up at the bank where they are opened.

Many companies generally have two personal seals, one of which is used for business, such as issuing a power of attorney and signing a contract. One is for financial purposes.
