Abstract
In the practical work of identifying the authenticity of document seals and seals, various types of highly imitated seal seals have emerged in recent years, which have the characteristics of multiple imitation methods, low cost, and high difficulty in identification. This poses a huge challenge to the authenticity identification of seal seals and seals. Traditional imitation methods such as using 1) manual carving; 2) Covering and piecing together single words; 3) Photographic plate making; 4) Computer scanning laser engraving [2]; 5) Forgery methods such as printing and copying. Document appraisers must be proficient in the characteristics of various types of high imitation seals in order to distinguish the authenticity of seals, perform outstanding appraisal work, maintain judicial fairness, and protect the legitimate rights and interests of parties involved. The author is based on a case of injection molded high imitation seal seals encountered in practical work. This type of seal imitation method is a new type of forging method, which has the characteristics of injection molded seal production, high simulation degree, and high difficulty in inspection. To address the identification needs of such high imitation seal seals, gypsum powder, silicone, and plastic raw materials are used to make gypsum models from real seals, By using a silicone [1] and A-B mixed hard glue reverse molding machine to carve ox horn seals and rubber seals, comparing and inspecting the gypsum mold with the real seal, the silicone seal with the rubber seal, the A-B mixed hard glue seal with the ox horn seal, the silicone seal with the A-B mixed hard glue seal, and summarizing the similarities and differences between the silicone and A-B mixed hard glue seal with the real seal, The analysis results can provide a theoretical basis for the inspection of this type of high imitation seal imprint.
