Research On Identification Of The Forming Method Of Stamp Impression

The seal plays an important role in daily life.Since ancient times,the seal has been praised as a symbol of power and identity.In the scene of signing documents and confirming matters,it is often affixed with official seals or chapters to confirm and have legal effect.It is precisely because of the important position of the seal that the seal is easily forged by criminal suspects to engage in illegal and criminal activities.The author believes that there are two reasons for the phenomenon of forging seals: Firstly,the seal is easily forged.After the criminal suspect obtains the seal and the printed master,he or she can create a new seal or seal by forging a seal or forging a seal to carry out illegal legal activities.The cost of making fake seals is low,which provides a convenient condition for forging seals.Secondly,the legal cost of forging a seal is very low.China already has strict regulations on the style of seals,but for illegal activities of forged seals,the statutory penalty is lower and the cost of illegal crimes is very low.The seal and seal identification is one of the common identification items in the practice of documentary judicial identification.The seal and seal identification mainly includes: the identification of the formation of the seal,the same identification of the seal and the seal,the identification of the seal formation time,and the identification of the sequencing.As a basis for the identification of seals and seals,the formation of seals has important significance for its research.At present,China’s research on the seal identification of seals mainly focuses on the research on the same identification of seals,seal formation time,sequencing and other test methods,and there are also a large number of such cases in the practice of identification,which is the identification of seals.The research provides practical experience and research ideas,and continuously promotes the development of seal printing and identification identification and identification technology.However,few people lack systematic research on the specific formation of the seal.The seal seal identification mainly depends on the original specimen.If the stamp printed on the original specimen is not stamped,the authenticity of the document is also doubtful.At present,the academic circles have less research on the formation of Indian languages and mainly focus on the research of conventional testing methods.Based on the objective analysis of the routine test method of the formation of the seal,this paper proposes a new method through theoretical research and experimental research.This article contains the introduction,which is divided into six chapters.The details are as follows:In the introduction,first of all,the author expounds the research background and research significance of the formation of the seal.Secondly,it summarizes and sorts out the literature and monographs on the formation of Indian seals at home and abroad,and clarifies the current status of research on the formation of Chinese Indian seals and the space for further research,which indicates the direction of this study.Again,explain the specific research methods used in this article,the inter-frame structure of the article,and the innovations and deficiencies.The first chapter is the theoretical support for the formation of Indian seals.Starting from the concept of the formation of the seal,the essential difference between the characteristics of the stamped and printed seals is clarified.From the perspective of academics,the reasons for the differences are discussed,which provides theoretical support for the following experimental research,and clarifies the significance and direction of the research on the formation of seals.The second chapter is the design of the experimental plan for the formation of the seal.The design of the experimental scheme is the most important part of the whole experiment.This chapter is based on the practice of the seal and seal identification and inspection.The experimental samples are often encountered in the practice of the inspection,and have guiding significance for the experimental research..The selected experimental methods and equipment are methods that areoften used in the case of inspection and have typical representative significance.The author mainly obtains the relevant scientific facts about the formation of the seal by the design and operation of the experiment,and further analyzes the generated data and pictures under the selected experimental conditions.The third chapter is the analysis of the inspection and identification techniques of the formation of conventional seals.Based on the experimental analysis of the second chapter,the objective test method is objectively evaluated.This chapter mainly deals with three conventional testing methods,namely microscopic test,video spectroscopy and laser Raman spectroscopy.The characteristics of each test method are analyzed by analyzing the collected test pictures and maps.Objective evaluation.Through the microscopic test method,the characteristics of the different types of printed characters are mainly observed,and the characteristics of the ink-jet characteristics,the support frame features,the printed surface features,and the oil-injection marks unique to the stamping and printing are mainly concerned.Through video spectroscopy,focus on the fluorescent,ultraviolet,and infrared characteristics of the printed text,as well as observing whether there are traces of oily substances,trace characteristics of laser printers,and so on.The Raman spectroscopy was obtained by laser Raman spectroscopy.It was found that the Raman spectroscopy of the stamped and printed ink samples was inconsistent with the laser-printed and ink-jet printed Raman spectra.Finally,the objective evaluation of various test methods is carried out,which lays a foundation for the system to construct the inspection and identification method of the seal formation method,and provides powerful scientific support for the problem of the formation of the seals encountered in the identification practice.The fourth chapter is to explore the formation of new techniques in the form of printing.This chapter is the innovation of the full text,mainly involves the exploration of two new testing techniques,namely the use of 3D shape profilometer and static voltage tracer to identify the formation of stamps.The 3D shape measuring instrument is used for statistical analysis from the aspects of morphology and mathematical statistics,from the traditional two-dimensional space to the three-dimensional space,providing a more intuitive scientific basis for identification.The static voltage tracer is used to investigate the effect of material materials on the visualization,and the scientific and stability of the method is verified.In order to ensure that the printing form inspection technology can be more accurately applied in the identification practice,through the mutual verification between differentinspection techniques and the empirical consideration and statistical analysis of the formation of the seal in the practice,the seal identification activity is guaranteed,scientific and reliable.The fifth chapter is the empirical study on the formation of seals.It selects the2013 seal and seal identification test plan project,and carries out inspection and analysis on the printed seals.It verifies the scientificity and stability of the new technology in practice and examines the case.The case of the formation of Chinese and Indian languages is summarized,and the proof effect of the appraisal opinions on the facts of the case is enhanced.
