An Experimental Study On The Sequence Of Paper Crease And Typewriting And Handwriting

In the judicial authentication of documents,in addition to the test of pertinence,the examination of the sequence of paper crease and handwriting is a kind of auxiliary test.In the forged document inspection and document identification in time,and the sequence of handwriting creases can play a supporting role,from the more subtle point of view to prove whether the file is formed in the normal order,in accordance with the normal order of documents are reliable.Especially in the identification of practice,when the limit conditions of samples for inspection is difficult to get an expert opinion,the inspection of multiple angles and nuances should be paid more attention.This paper is divided into four chapters.The first chapter introduces three elements that influence the sequence of handwriting and crease,which are handwriting,paper and crease.Among them,three handwriting tools and three printing machines are chosen finally.The six forms of writing can be divided into attachment type and penetration type,and there are different forms of the formation of creases and handwriting.The second chapter is the specific introduction of the materials for the preparation of experimental samples,as well as the experimental instruments and testing methods.The third chapter is the key part of this paper,which is divided into three parts.It includes the display,description and summary of the experimental samples by two instruments using microscope and instrument.There are different apparent features,and the different handwriting tools will also have different appearance characteristics.The microscope and VSC are focused on differentinstrument functions,so the observation of handwriting phenomenon on the crease will have their own emphases and advantages.All in all,the third part summarizes the observation phenomena of the two kinds of instruments.The fourth chapter,combined with case practice,introduces the role of crease and handwriting sequence in practice and the role it can play.Appeared with the development of science and technology,more inspection technology and the method can be used.The single inspection technique and method are not sufficient to provide sufficient basis,and the expert opinion is not strong enough.The sequence of handwriting and creases is a kind of auxiliary test method,which lacks a comprehensive theory summary.This paper describes phenomena in a variety of angles,such as strokes of integrity,ink form,paper fiber changes,crease change.By using different instrument to observe,compare and induce the apparent differences,it will help the practice test related documents through experimental research methods.
