Method for identifying seal and print formation mode based on microcosmic trace point characteristics

Abstract

The invention relates to a method for identifying a seal and print formation mode based on microscopic trace point characteristics and belongs to the technical field of document examination. The method mainly comprises the following steps: (1) carrying out macroscopic examination on seal and print based on objective facts and living knowledge; and (2) deeply analyzing the seal and print by utilizing the microscopic trace point characteristics, wherein the microscopic trace point characteristics includes ink mark characteristics, ink point characteristics and dot characteristics; the seal and non-plate-making printing print are identified by adopting the ink mark characteristics and the ink point characteristics, and the plate-making printing print is identified by adopting the dot characteristics; and when no dot characteristic exists, whether the seal and print are sealed or printed in a non-plate-making way or formed by a woodblock and a metal plate in letterpress printing is judged, and when the dot characteristic exists, whether the seal and print are formed by the plate-making printing print is judged. The method provided by the invention has the beneficial effects that print production method identification utilizing the trace point characteristics is high in examination accuracy and convenient in operation and thus is a nondestructive and fast identification method.

Description

technical field [0001] The invention relates to a method for identifying the formation mode of seal imprint, in particular to a method for identifying the formation mode of seal imprint based on microscopic imprint features, which belongs to the technical field of document inspection. Background technique [0002] Since the 1940s, the content of seal identification, typewriter identification, and forged document identification has been enriched, forming the traditional content of document inspection technology. The seal formed by hand-stamping has always existed in social activities as a form of seal formation that is generally recognized and trusted by the society. With the development of electronization, automation and informatization of printing technology, the process, technology, equipment and materials of color printing are constantly changing. We are facing a "color revolution" that is popular in the global printing industry. As a sign of legitimacy in modern society...

Problems solved by technology

This type of pattern identification method and idea began in the 1950s and 1960s and continues to this day. Among them, the understanding and utilization of dot characteristics have always remained in the inspection and identification of overprint documents of the three primary colors in lithographic printing, and the dot microstructure has not been considered. As the basis for the distinction of various versions, it is applied to the level of document inspection and identification
