An Empirical Study On The Identification Of Steel Seals

Seal,also known as seal,stamp.The seal of China has a history of thousands of years.It can be traced back to the Xia and Shang dynasties.It is a unique culture of China.From the beginning,it represents the declaration of ownership,and later used by the painters,and even developed into a unique art,the seal has an indispensable position in our lives.At present,the seal is widely used in various instruments,which is an recognition of its authenticity and effectiveness.Steel seal is a kind of seal.Compared with the traditional metal engraving seal,rubber seal and photosensitive seal,its application range is relatively narrow,but it often appears in special documents such as graduation certificate,degree certificate,marriage certificate,and some legal documents.With the increasingly fierce market competition and the severe employment situation,the state's emphasis on talents has led to the emergence of illegal cases such as forged academic qualifications and degree certificates,which inevitably leads to the forgery of the seals.Therefore,it is of great significance to carry out research on the impression of steel seals.At present,the research on the impression of steel seals is still in its preliminary stage,and there are few references.The author hopes to further explore the characteristics,influencing factors and the same identification of the seals on the basis of existing research,and deepen the understanding of the seals.The content of this article is divided into six parts.The following sections briefly introduce the contents of each part.The first chapter is an overview of the steel seal and the impression of steel seals.This part describes the design of the stamp and the process of making the stamp,and introduces the formation of the stamp.The second chapter is the classification of the characteristics of the impression of steel seals,from the characteristics of the stamps to the characteristics,and a simple comparison with the traditional stamps.The third chapter is the experimental research on the influencing factors of the characteristics of the impression of steel seals.This chapter is one of the key points of the thesis.It is divided into four parts: the purpose and principle of the experiment,the experimental scheme,the experimental results and the analysis,and the experimental summary.Mainly from the changes of stamping pressure,the change of the number of stamped papers,the change of paper type,the different specifications of the same kind of paper,the effects of the change of stamping conditions on the characteristics of stamped characters are discussed.Through this chapter,we can have a deeper understanding of the characteristics of the stamp and seal,which is conducive to the subsequent identification work.The fourth chapter is the identification of the identity of the impression of the steel seal.It mainly introduces the identification of the identity of the impression of the steel seal,what is included,the theoretical basis of the identification,the procedure of identity identification and the specific identification method.Although there is no big difference between the identification of traditional seals,there is a unique place in image processing.At the same time,in the way of printing the seal,the author encountered a simple stamp,summed up the characteristics and identification points of the stamp.The fifth chapter is the identification of homologous steel seals,which is another focus of this paper.It is also a major difficulty in practice.This paper comprehensively analyzes the theoretical basis of the identification of homologous steel seals from the production of steel stamps,material differences,processing of stamps and the use of stamps.The inscriptions between the four identical seals were carefully analyzed to prove the correctness of the theory.It was finally found that apart from the two seals and the identically identical seals,the other two could be distinguished and the causes analyzed.The last chapter is the conclusion,which is a summary of the full text.The whole research process will be sorted out,the research results obtained will be summarized,and the existing deficiencies will be reflected to accumulate experience for better research and improvement in the future.This paper introduces the systematic impression of steel seals,from the production of printed manuscripts to the characteristics of printed characters,to the identification of the homologous seals,and summarizes the identification points,hoping to help judicial appraisers..In the future,it is necessary to study the impression of steel seals and forged seals on paper with content,and to construct a complete theoretical system.
