First, the basic requirements for the use of official documents: for official documents with seals, the date of writing is generally arranged in the right space, and the seal is red. Blank seals are not allowed. When writing for a single organ, the signature of the issuing organ is generally arranged in the center above the written date, which shall prevail. The signature and written date of the issuing organ are pressed down in the center, so that the signature and written date of the issuing organ are in a lower position in the center of the seal, and the top of the seal should be within a line from the text (or annex description). When writing jointly, the signatures of the issuing authorities are generally arranged in the corresponding positions according to the order of the issuing authorities, and the seals are in one-to-one correspondence, which is correct and centered on the signatures of the issuing authorities. The last seal is correct, and press the signature and written date of the issuing authority in the center. The seals shall be arranged neatly, without crossing or tangency, and both ends of each row of seals shall not exceed the center of the edition. The top of the first line of the seal should be within one line of the text (or annex description). For an official document without seal, when a single organ writes, the signature of the issuing organ should be arranged in a blank line under the text (or annex description), and the date of writing should be arranged in a blank line under the signature of the issuing organ, and the first word should be shifted to the right than the first word signed by the issuing organ. If the writing date is longer than the signature of the issuing authority, the writing date shall be arranged in a blank line, and the number of words of the signature of the issuing authority shall be increased accordingly. When writing a joint article, the signatures of the host organ should be arranged first, and the signatures of other issuing organs should be arranged downwards in turn. For the official document stamped with the signer's signature, when the official document issued by a single organ is stamped with the signer's signature, the signer's signature is stamped with the words "two lines, right space" and "four words" below the text (or annex description), and the word "signature" is left space to mark the signer's position, which is arranged in the upper and lower middle based on the signature. Write a written date under the signer's signature stamp, with one line on the left and four words on the right. When writing jointly, the issuer's post and signature seal of the host organ shall be given priority, and the issuer's post and signature seal of other organs shall be arranged downwards in turn, aligned with the issuer's post and signature seal of the host organ; Only one issuer's position and one organ's signature seal are arranged in each row; The position of the issuer shall be marked with the full name. The signature stamp is usually red. Second, the specific requirements of document paper type: document paper type refers to the format size of document paper. According to the provisions of Article 12 of the Regulations on Handling Official Documents of Party and Government Organs, the paper format of official documents adopts the international standard A4, that is, 297mm×2 10mm (length× width). The paper format of special official documents should be determined according to actual needs. The expression form of the main sending organ and the labeling and arrangement of the cc organ in the official document teach you to become a master of official document writing.
